Sup pplz just bought some koobloom for my gals, was wondering if I should add it every res change or every topping??? And also I'm doing DWC bubblers, how do I flush during the last week or 2?? just with tap water instead of adding nutes? Thanks

you can only use it like once or twice in last weeks of flower before you flush

actually koolbloom has two parts, a liquid and a powder. they are used at different times. One towards the beginning, one towards the end.

Koolbloom is just a P/K booster, it can be used whenever during a grow. I just don't recommend you keep it in the mix all the time. Currently for me my rez will see koolbloom 14 days total during flower. I mix it into the rez during week 3 and also during week 5. Rez gets cleaned and refilled every week except first 2 weeks.

Thanks guys.
Jm, Well I'm 48 days in its past the hermes stage no?? On my next round ill look into using the liquid kb then
Tokin, do u use anything else to boost? I'm not looking to put too many additives in the res until I get everything dialed in. I just want to stick with some good benes and a good booster for a couple of runs.

Use KB powder very sparingly, at less than half package strength to start with.

I believe the KB will likely kill most benes in your system? Can anyone validate this? I remember reading about high P concentrations killing microflora.
 
Running bennis in a chemical drip i have found them much harder to kill then most people seem to think.....

Even the bayer tree and shrub doesnt effect the thick mat of bennis over everything...

They do fine with monsterbloom, and the FF boosters, they got to be as strong if not stronger then koolbloom...

Good to know thx desertsquirrel. In any event KB powder is quite strong 2-45-28 so use sparingly until you know how it will affect your particular strain.

Here's how I use it. I just started using it and it is EFFECTIVE. Mix your nutes. Mix 'em well and make sure you do NOT go over 1200PPM on the .5 conversion ok! Do not go over 1200PPM on the .5 remember this!! Now add the KoolBloom to the prepared nutes. The KoolBloom cannot exceed 200PPM from you already prepared nutes. Now thats 1400PPM on the .5. You're done. Now wait a few minutes and adjust pH. pH liquids will rise your PPM but to not pH till nutes are mixed well. 2 days later you will see then busting very white pistils. These are new growth points. In a week you should see possible fox tailing from buds growing on buds. LoL Its really sick!! To be used in last half of flowering.

Remember too much will kill your plant or cause bad hermies!! Use only 200PPM over set prepared nutes. YOU NEED A PPM METER! If you do not use a PPM METER you will most likely mess something up by adding too much. A pinch of this stuff may be too much it it SUPER CONCENTRATED! No need for liquid KoolBloom.

foaf thinks that liquid koolbloom is more than "just a p/k booster". GH describes as "Enriched with stress reducing vitamins and nutrient transporting acids". on the MSDS sheet the odor is described as a musky vitamin odor. GH does not list the exact composition of liquid KB, but foaf can smell vitamin B for sure. it would be nice to know what is exactly in it. foafs guess is that they have also added vitamin C, maybe L-Ascorbic acid 2-phosphate magnesium ester, and possibly some amino acids.unfortunately all we can do is guess until GH gives us the full compositions of their plant enhancement lines. somebody could at least find the elemental NPKMgS by sending a sample to a lab.

this is what GH says about koolbloom.as foaf understands they only list where the formula is derived; meaning the NPK is derived from that source. foaf thinks there is probably a little magnesium and sulphur they are not listing.
"The chemical identity of the compounds and exact proportions used
in the mixture are a trade secret. Liquid KoolBloomTM Ripening Formula is derived from
magnesium phosphate, potassium phosphate, and potassium sulfate."

what foaf is wondering is when they say "derived from", if they are just adding a specific ratio of magnesium phosphate, potassium phosphate, and potassium sulfate to make the 0-10-10 NPK, or if they can remove the amount of magnesium and sulphate ions in solution?
what do you guys think, is there more than just P and K? is there Mg and S in the liquid KB?

http://en.wikipedia.org/wiki/Monopotassium_phosphate

Monopotassium phosphate -- KH2PO4 -- is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium. It is also a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level.

Fertilizer grade MKP contains the equivalent of 52% P2O5 and 34% K2O, and is labeled 0-52-34. MKP is often used as a nutrient source in the greenhouse trade and in hydroponics.

The liquid is just watered down, and since they dont list a % of Mg or S you cant read too much into it. I agree there is probably more Mg and S than the minimum listed.

MPK 0-52-34 is awfully similar to Powder KB 0-45-28.

52/45 = 1.1555
1.5555 x 28 = 32.4 (close to 34).

Understand?

^ NPK?

not to be a stickler :scripture:

It confused me for a second cuz we were just talking about Mag.

EDIT: Apologies. The MPK is in reference to the Wiki article above. My bad.

So bottom line.. the liquid is just watered down from the powder?

Sorry for busting in on your forum. I use soil but rock Lucas and KoolBloom. With some extras.. Same nutes as i ran in Ebb and Flow back in the day. ...old habits.

Results ok i guess.

I have used this product several times in the powdered form, always half strength...no hermies.

Liquid koolbloom has a pH of 6.1; not very acidic-if you don't believe Indo put your pH pen in the bottle.

firstimer76-how can it drop pH to dangerous levels if the pH of the liquid KB is 6.1?
 
Rezz uses as much as 5 teaspoons per gallon in addition to his 6/9 doesn't he? I agree with the 200ppm because more is over kill but i wouldn't be too worried about it causing herms or anything.

Nope, my girls get GH flora 3 part and koolbloom. Sometimes I'll add in a little extra cal-mag if they are starting to look Mg deficient. Nothing other than that, pretty simple and quite effective.
