1 tsp per 5 gallons. I used it every other watering with great results. I still used my original nute formula, just added that a little under label instructions. Good luck!
I use a product called Crazy Bloom and I find it works good also. I think they are basically the same - I use a little under what the label reads also. 1 tsp per 5 gallons. I find the plants go through water a little quicker when I use this stuff.
I've used monster bloom for about five years and have always had fantastic results. I credit it for the sticky icky nasty sappy buds i get when used in conjunction with high-phosphorous bat guano. When you check the ppm's at full strength, as per the jars instruction, it was between 750-800, you could probably run this double strength in hydro; i never have, I just ran it per instructions in hydro and had some incredible buds. I've been using slightly more than the jar says for the last 2 years-1/4 teaspoon per gallon as opposed to 1/5 teaspoon, which i don't have. Feel free to use other bloom products with this stuff, I wouldn't use it without guano though. I totally recommend it for anybody who wants the dankness in their garden...oh, makes a fantastic foliar at 1/4 strength(110-180ppm).
Im running it in soil, and can see a difference between the plants that have had it and the ones that didnt, well I could until I said LETS and gave it to them all.
I've been mixing 1/4 tsp per 3L of water without any problems
I fucked up...it's +-1100 ppm's at 4x strength....i just put this strength batch on some 1 gal. SOG style plants and they look great. It's +- 250ppm's as per the jars instructions. Sorry for any inconvenience.
