But the benefits don’t stop there! Along with giving you earlier flowers, more flowers and bigger flowers, Bud Blood bloom stimulator also:

Reduces crop losses
Increases flower size and number
Stimulates stronger, larger root systems for faster growth and bigger flower formation
Provides instantly available, high quality nutrition for more vigorous growth/production
Reduces production costs by shortening crop cycle length
Increases flower appearance, aroma, & taste for higher value crops

What’s more, Bud Blood provides these benefits in ways that cannot be duplicated. Bud Blood is the only all-in-one formula that gives you such impressive gains in your garden.

Accelerated crop cycles have long been a goal for you and other gardeners. But before Bud Blood was available for you, there really was no reliable way to force crops to go into flowering earlier and be ready for harvest sooner.

Before Bud Blood, some growers cultivated specific types of plants known to be short-season crops. Other gardeners settled for shorter vegetative cycles so they can flip their plants into flowering sooner.

BUD BLOOD GIVES ME THE LARGE HARVESTS I WANT “I was using the best hydroponics nutrients and a bloom booster or two. I got some good results but not like I saw in magazines, not those huge buds that other people were getting. I also started to notice that my crops were taking longer to be ready for harvest than what they were supposed to. Like when the seed catalogue said they were supposed to be ready for harvest in 45 days, but it was taking mine about 60 days, or even longer, and I really wasn’t getting the huge yields I expected, especially for that long of a growing season. I used Blossom Blood, but it didn’t make any difference. Then somebody told me to use Bud Blood, and when I did, I noticed that the flowers developed sooner. I saw that I was getting larger flowers and I also was glad to see that my harvest cycle was shortened so that my 60-day crops were ready at 45 or 50. This allowed me to pack in more grow cycles, which saves me money on lighting, electricity, time and other costs, and gives me bigger total harvests. Thanks for making a formula that actually does what it says. Blossom Blood didn’t do nothing, but Bud Blood really works good for me because it gives me the larger harvests I want, and sooner.”
- David K, from Lakeland, Florida

They’d prematurely switch their light cycle to 12 hours and then wait what seems like forever for plants to flower. In some cases, the plants were just too young to properly flower, so they’d exhibit stress symptoms- including tiny, malformed flowers.

These typical methods have loss attached to them: they result in smaller yields. And guess what? In about 50% of the situations, these methods don’t even result in shorter seasons.

With Bud Blood, you don’t have to use these outdated methods. You just feed Bud Blood to your crops, and then enjoy the larger, earlier harvests you get.

What Is Your Present Level Of Harvest Costing You...?

BIGGER AND FASTER HARVESTS SAVED THE DAY! “I planned an 8 week bloom cycle in my grow room and everything was on track. But then my 6-year-old son was diagnosed with leukemia and we were told we had to move to another city to be close to a specialist hospital and doctor, so I needed to end the bloom cycle as soon as possible. I asked your tech advisor if there was anything I could do to speed up the bloom cycle and he said to use Bud Blood to get the flowers as fast as possible and make them as big as possible before I had to shut the system down. Bud Blood did make the flowers develop faster and they grew bigger faster, so even though I shut down early, I still had a good harvest. Your stuff saved the harvest, and the really good news is that my son was able to overcome the disease.”
- Bob, from Topeka, Kansas

Bud Blood bloom enhancer gives you harvest-boosting, time-saving benefits because it contains an exclusive mix of specialized hydroponics ingredients chosen by scientists who’ve studied floral triggering and development.

You can check out our list of scientific references below, but a quick explanation is that Bud Blood contains superior forms and perfect ratios of potassium, phosphorus,sulfur and other key bloom-enhancing ingredients. Bud Blood has a combination of nutrients and other ingredients that few hydroponic nutrients have.

What’s more, Bud Blood contains the bud-boosting power of kelp-derived gibberellins. These substances are a potent stimulator of flower and fruit development. They increase the size, weight and quality of flowers and fruits by turning on the plant’s regulatory system that makes it produce larger harvests. Better yet, Bud Blood contains a proprietary form of two kelp-derived gibberellins that we’ve tested extensively in hydroponics gardens.

What’s this mean for you? It means bigger, heavier, earlier harvests because these ingredients feed plant systems and processes responsible for bloom timing and formation.

It also means safer, stronger plants because these ingredients have been scientifically proven to help plants resist stress from improper pH, nutrient deficiencies, water problems, and oxidation.

Are Your Flowering Buds Getting Control Over You, or Are You Controlling Them?...

USE IT FOR A SHORT TIME AND SEE LARGER HARVESTS “One thing I noticed about your Bud Blood is that I don’t have to spend much time with it. It mixes easy with other additive and the hydroponics nutrients program. I only used it for about 3 weeks. I could see that the flowers popped out on the plants a lot quicker. And also I could see that later on they were bigger. So this is what I wanted when I bought it and I am glad it came through for me.”
- Rob C., from Glastonbury. England

The bottom line is that using Bud Blood bloom stimulator allows you to “push a botanical button” that turns on flowering earlier while creating larger, better-formed, more valuable flowers.

And this happens real easily. You’ll be glad to know how convenient it is for you to bring Bud Blood’s many benefits into your garden. Bud Blood mixes quickly. No mess, no bother.

It blends perfectly with your base fertilizer and with other additives. Better yet, it does its magic even though you only use it during the initial transition when you switch your plants from early growth to bloom phase.

Many people mistakenly think of Bud Blood as just another “bloom booster.” While it’s true that Bud Blood causes blooms to swell up, its ingredients and effects extend far beyond those offered by bloom boosters.

For example, Bud Blood strengthens roots and enhances their performance so they take in nutrients faster and more efficiently. This results in better floral growth, as well as lower fertilizer costs.

Another great thing that Bud Blood provides you is increased quality of your flowers. You’ve already found out that Bud Blood makes your plants flower earlier and have more budding sites. You’ve already learned that Bud Blood makes flowers bigger.

Bud Blood Gives You Faster Harvests, Bigger Harvests, and Higher Quality Harvests

But along with those benefits are other plusses. Bud Blood stimulates production of floral and fruit substances that make your harvests have better aroma and taste. It also makes fruits and flowers look better, so they have higher market value.

The good news keeps on growing. Bud Blood protects your larger, more numerous and higher quality buds by protecting plants against stress-related problems, heat and drought. It also helps plants defend themselves against diseases.

Phosphorous
Phosphate appears to play an important role in the flowering of Lemna paucicostata 6746, a short-day duckweed. Phosphate and calcium partially remove the inhibitory effect of sucrose on photoperiodic flowering in 1/50 strength Hutner's medium (Posner 1969) and also partially reverse the inhibition of photoperiodic flowering caused by transfer to distilled water for short periods of darkness (Haraban and Hillman 1970). A recent study (Mori 1984) found that iron and phosphate could enhance flowering in. 1/10 Hutner's medium under uninterrupted darkness.

Potassium
In the above experiments, the efficiency of fruit setting, i.e. the percentage of the total number of flowers which produced fruit, fell significantly in conditions of potassium deficiency (Table 3), and was less than 66 per cent when the nutrient feed contained concentrations less than 2.3 me K+/1. Since both the final flower number and fruit setting efficiency were reduced under these conditions, the number of fruit produced per plant was also lower at the lower potassium treatments. The total yield of fruit per plant reached a maximum with the 5.03 and 10.23 me K+/1 treatments.

Maximum fruit yield without the production of excessive foliage was associated with 5.2 i 0.8 g K+/100 g dry weight in the whole leaf (3.8 ± 0.6 and 8.1 =h 1.1 in the laminae and petioles, respectively).

Phosphorous
G3 does not flower in NH4+-free 0.5 H medium (Tanaka et al. 1979), but increasing the phosphate concentration from 1.15 mti to 12-20 mM results in substantial flowering (Cleland and Tanaka 1986). The results suggested that flowering may be inhibited by the decrease of phosphate concentration even in E medium. Flowering was induced in standard E medium with 5 mM phosphate but suppressed by lowering the phosphate concentration in the medium (Fig. 1), confirming our results that a high concentration of phosphate is required for the induction of flowering in Lemna gibba G3 (Cleland and Tanaka 1986).

Bud Blood Increases Your Yield and Quality

Potassium
The application of an adequate supply of potassium to tomato plants is important in vegetative growth and in the production of fruit of good quality. A change in the availability of potassium to the plant significantly affects the composition of both the foliage and the fruit.
“Effect of Potassium Nutrition on Tomato Plant Growth and Fruit” in Plant and Soil. 1975. 42: 395-412

Phosphorous
Ten days of phosphorus deficiency results in a decrease in the number of flowers that develop on the first truss of tomato plants. This effect on flower number is accompanied by a decrease in the cytokinin activity of the root exudate. The involvement of cytokinins in flower development is further implicated by the fact that application of kinetin to the growing medium increased the number of flowers produced by the seedlings.
Australian Journal of Plant Physiology, vol.3 (1976)

Potassium
Total dry weights of 6-wk-old plants grown in sand were maximal when the nutrient feed contained 0.53-5.03 me K+/1, although plants receiving 10.23 me K+/1 retained more water in the foliage and therefore had the greatest foliage fresh weight. Both peduncle length and height of the basal truss were increased by K in the feed up to 10.23 me/l, the highest concentration used. Flower development was retarded below 0.53 me K+/1, and fruit setting efficiency was reduced below 2.03 me K+/1. Fruit ripened faster on plants receiving low concentrations of K. Maximum fruit yields were produced on plants grown ill sand receiving 5.03 or 10.23 me K+/1.

Phosphorous
Results show a significant yield response to super-phosphate. Long-term applications of ammonium sulphate resulted in severe reduction of vine growth and yield, and a significant lowering of soil pH. No direct response to potassium sulphate was obtained except in one year, but a positive interaction between potassium and phosphorus occurred in some years. An analysis of the components of yield in 1964 showed that the increase in yield with superphosphate was due to an increase in the number of berries per bunch.

Potassium
Plants receiving K fertilization yielded more than plants that did not receive any K… The lint yield increased an average of 9% during these 2 yr… In 1996, the 112 kg K/ha plants produced bolls 8% heavier compared with the 0 kg K/ha treatment. This larger boll mass could be attributed to more seed per boll, greater seed mass, and more lint/seed (lint index) found with the 112 kg K/ha treatment compared with the 0 kg K/ha. In 1997, the production of 4% more bolls per unit of ground area was the principal yield component contributing to the yield increase observed with the 112 kg K/ha treatment. In addition, the 112 kg K/ha treatment had a 4% greater seed mass than the 0 kg K/ha treatment in 1997.

Bud Blood increases production of isoflavones

Increases flower structure and pigment (attractiveness)
Improves flavor and aroma

[Isoflavones] are thought to contribute to the healthful effects of soybean in human and animal diets. …isoflavones in soybean seeds possess functions of antiestrogens, antioxidant, and tyrosine protein kinase inhibitors.

“Potassium Fertilization Effects on Isoflavone Concentrations in Soybean [Glycine max (L.) Merr.]” in Journal of Agriculture and Food Chemistry. 2002. 50:3501-3506

Two classes of the major nutraceutical components studied in fruits include flavonoids and isoprenoids. Flavonoids such as quercetin and catechin are strong antioxidants and powerful inhibitors of calcium (Ca) second messenger function. Isoprenoids such as lycopene and carotene are also strong antioxidants.

Potassium
Significant and positive responses of daidzein, genistein, and total isoflavone to direct deep-banded K or residual surface-applied K were observed on low-K soils. Potassium application and placement effects on isoflavones were sometimes significant on medium- to high-testing soils... In addition, appropriate K fertilization practices were more beneficial to isoflavone concentrations than changes in other management factors such as tillage systems and row widths.

Potassium
K is well known as an essential activator for many enzymes in various metabolic pathways in plants. It is possible that the observed K fertilization effects on isoflavones were due to the stimulation of some specific enzymes involved in isoflavone synthesis, as was suggested for lycopene synthesis in tomato.

Phosphorous
Both the flavonoid biosynthetic pathway and the isoprenoid pathway are heavily dependent on phosphorus (P)-containing metabolites such as ATP, NADPH, and sugar phosphates derived through the pentose P pathway. Thus, P fertilization may have a direct effect on the levels of these metabolites, and potentially in the levels of the end products such as flavonoids and lycopene.

Bud Blood stimulates a stronger, more extensive root system

Faster, more efficient nutrient absorption
lower fertilizer costs

Phosphorous
Exposure of parts of the main seminal roots (axes) to high concentrations of phosphate caused a localized promotion of the initiation and subsequent extension of both first and second order laterals, compared with zones receiving very low concentrations of phosphate.
“Comparison of the effects if a localized supply of phosphate, nitrate, ammonium and potassium on the growth of the seminal root system, and the shoot, in barley.” In New Phytologist. 1975. 75(3): 479-490.

Potassium
In contrast to the other ions studied, potassium supplied to a single zone enhanced lateral growth throughout the root system although potassium-deficient plants (treatment 3) had a poorly developed system of lateral roots. Our results therefore, broadly support Wiersum's conclusions (1958) that nitrate and phosphate are more important in stimulating lateral root initiation than potassium.

Phosphorous, nutrient ratios
localized placement of nitrogen and phosphorus fertilizers in a nutrient-deficient soil promoted root proliferation only when both nutrients were present in the same rooting zone: that is, omission of a single essential nutrient has marked effects even in the presence of ample concentrations of all others.

Potassium
“Summer squash” (Cucurbita maxima var. zapallito (Carr.) Millán) is a monoecious species and the reproductive stage starts with female flowering. A male to female flower ratio lower than 10:1 results in greater fruit setting and yield. This relation is controlled by environmental factors, growth hormones and nutrients. The aim of this study was to evaluate the effect of the N:K ratio on sex expression, fruit setting, earliness and yield on the summer squash.
“Summer Squash (Cucurbita maxima var. zapallito (Carr.) Millán) Earliness and Yield as Affected by the Nitrogen:Potassium Ratio”. In Agricultura Tecnica. 2003. 63(4): 428-435

Potassium
The number of flowers was greater for the relations 50N:50K and 50N:100K than for 50N:0K. The increment in the K fertilization did not affected the number of male flowers, but decreased the male to female flower ratio due to higher female flower production. The number of fruit set was lower at 50N:0K, without significant differences between 50N:50K and 50N:100K. The highest early yield was obtained with 50N:50K and 50N:100K, with respect to 50N:0K. The highest marketable yield was obtained with 50N:100K because of a greater marketable fruit number, since there was no significant fruit weight difference with fertilization.

Bud Blood reduces damage due to drought

Potassium
The percentage of live roots was reduced by drought stress at all K levels, but the largest reduction in percent live root occurred at K0 (Figure 3). Drought stress caused 44% reduction in the percent live root of Hibiscus plants at K0, compared to 26% and 20% reduction at K2:5 and K10, respectively.
“Effect of potassium on drought resistance of Hibiscus rosa-sinensis cv. Leprechaun: Plant growth, leaf macro- and micronutrient content and root longevity” in Plant and Soil. 2001. 229: 213-224

Potassium
All the treatments were fertilized with Hoagland’s nutrient solution, modified to supply K as K2SO4, at 0 mM K (K0), 2.5 mM K (K2:5), and 10 mM K (K10), under two irrigation regimes (drought stressed [DS] and non-drought stressed [non-DS]). ... At K0, plants were K-deficient and had the lowest leaf K, Fe, Mn, Zn, Cu, B, Mo and Al, and highest Ca concentrations. Although the percentage of live roots was decreased by drought stress, K2:5 and K10 plants (with similar percent live roots) had greater root survival ratio after drought treatment than the K-deficient plants. These observations indicate that adequate K nutrition can improve drought resistance and root longevity in Hibiscus rosa-sinensis.
