I've done extensive research and this is one of the "cleanest" bloom boosters for mari jane. The components that "stress" the plant into early ripening are Ammonium Phosphate & Ammonium Sulfate which are both in this product, those are the only 2 differing ingredients from the Koolbloom liquid. Personally I use the product @ +100 ppm (500 scale) weeks 2 through 4 and then weeks 4 through 8 I apply at full strength 200 PPM on top of my base feed. Results are amazing. The product gives your plants a boost of Phosphorus, Potassium, Magnesium & Sulfur.
Sulfur helps in the terpene oil production and definitely provides stronger smelling flowers. The different forms of Potassium & Phosphorus really assist in bulking up the flowers.
DO NOT EXCEED +200 PPM OF THIS PRODUCT you will get a counter-effect where it actually stunts buds. Start low and monitor plants for a few days before increasing strength. Feed normal base nutrients as you would and just add 100 ppm of this product.
General Hydroponics did an excellent job making this a dry measure product, weighing in teaspoons really works perfectly. For 1/2 strength you will use 1/4 teaspoon per 2 gallons of water or 1/8 teaspoon per gallon. Full strength is 1/4 teaspoon per gallon.. I would not recommend exceeding that.... More won't make the buds bigger it will just stress your plants out and make the product harsh.
I recommend discontinuing the use of koobloom and just use normal fertilizer for the last 7-10 days prior to harvest. There is no EXACT way to use it though so trial & error is your friend.
IMPORTANT: do not exceed 200 PPM or 1/4 teaspoon per/gallon of this product. It will just cause adverse effect..
This product will lower your pH of your nutrient solution, you will need to increase your pH up a little to account for it. I personally just increase how much Potassium Silicate (silica) I add before mixing. Tinker with it until you get it down.
Thanks General Hydro for great products.

The most amazing results I have seen. The amount you use is 1/4 t. per gallon. You will get flowers so heavy they bend down, and will even rip away from the stalk if not supported. I would recommend using a silica supplement to help strengthen the branches, they will need the help. Start with the liquid and finish with the dry. The liquid helps the plants form extra bud sites. When done right, the branches will fill out to be solid spears. Your stuff will look better than sugary, it will look salty, like it has been rolled in course salt. Make sure to be ready for copious amounts of scent too. I run these products at 1500 ppm with a starting hard water reading of 200ppm. I usually begin at a weaker 800ppm reading for the first week of flowering. My preference for ph rating is in the high 5 range. The stuff even likes to be used with plain tap water. General Hydro does it again.

Started using the General Hydroponics Flora fertilizers recently and was happy with the results but decided to try out the Kool Bloom supplements. These products work great, they are like steroids for plants. Also the package is 1kg not 2.2 oz, it only takes a small amount and the bag should last quite a while. One thing I do is to mix the dosage in a liter of hot water to make sure it totally dissolves. I am extremely happy with this product and highly recommend it along with the Kool Bloom liquid. Funny thing I tried buying the Kool Bloom powder at my local grow store they said it was back ordered and had no idea when they would have stock, but found it here at a premium, still happy.

in the last few weeks of flower this will help your ladies put on some serious weight. i use it the last 2-3 weeks before flush and i have noticed a big difference using this in the last few weeks over the liquid cool bloom. the fact that they can in fact add so much more bulk when you think they are done is quite intriguing. I am by now means a master grower nor to i claim as such but i am experienced and i know when i am wasting my money on a product, i have tested many different lines of nutrients and my go to regiment is consisted of several different brands. this is now a permanent part
use it you will not regret it

Even the astronauts use this for it's superior Ph stability & guaranteed high performance. Most of all your fertilizers on the market do not contain Calcium, Molybdenum, or Cobalt. This does. So, if you want your tomatoes, peppers, squash, aloe, baby's breath, lavender, watermelons, and whatever else you want to grow to thrive; then look no further. This is a "Micro" formula which must be used with a "Macro" fertilizer as well. For Vegetative growth I use Sea-Grow 16-16-16 and Sea-Grow 4-26-26 for flowering, fruiting, nutting, & budding growth along with the FloraMicro :)

This stuff works amazing for the last week or 2 before flush, this stuff shocks the plant into producing ridiculous amounts of resin and trichomes (ie cannabinoids and terpenes) DO NOT USE MORE THAN RECOMMENDED. Like i said, this stuff is MADE to shock the plant, increasing it will not turn out the way hope it will. Use too much and (if your plant survives) it will be greatly stunted and all your buds are now FULL of nutrients. Some of them are immobile nutrients which means no amount of flushing will get rid of them.

I love how well this brand worked with an auto watering system. It's not thick. But that's it. Down side, the container is messy. It's all but impossible to not drip and spill while shaking and/or pouring. I should at least be able to shake the container like the directions say, and not worry about wasting a mix worth to make a mix. I make 4-5 gallon mixes. Pouring into a measuring glass is just as fun. The nutes flow in the glass and down the bottle to the sink at a 90 degree and below..the waste is unreal.

I’ve seen great results my first time using this. It does everything it says it will do. However, I am using max lighting and noticed I can up the nutrients 3x the recommended dose. (I do not recommend doing a 3x dose unless you’re very experienced.)
I upped the dose by 1/4 teaspoon over 10 waterings and still the plants wanted more (yellowing a bit prematurely.) I had to flush before I got the dosage raised the proper amount, so I may consider adding it in top of the liquid kabloom next time.

This gives your plants an extra high dose of phosphorus and potassium and a small amount of Nitrogen during the end of the flowering period. If your skeptical learn about NPK, this fertilizer is what "tomato" plants want in its final weeks.
YOU WILL NOT BE DISAPPOINTED. ROCK HARD SWOLLEN MONSTER "TOMATOS"..... HUGE NIGHT AND DAY DIFFERENCE FROM LAST YEARS. FOLLOW INSTRUCTIONS ITS VERY SIMPLE. You cant go wrong and will buy again.

This stuff is the butter to your bread. I've never used anything else and brother, my basil is some of the strongest and tastiest in the seven kingdoms and beyond. All anyone needs is this and the pretty pink stuff and you can make your plants go "kerboomkaplow" in no time, huge vegetative growth and consistent yields is what any farmer needs. This is the basic tool, your pencil to paper, it's a must have for any serious grower.
