Benzelsanswered grow question 2 years ago Dont waste your money on a whole host of products unless you have a REALLY nice light that throws out ALOT of light. Then its worth trying diff products to see if you can get the most out of the lights potential. Your limited by your light, not by the products you use. If you have a cheap basic light that is low on watts, then it wont matter what high end nutes or additives you use, the plant isnt getting enough light to take advantage of them to grow any faster. Does that make sense??
Humic/fluvic Acid is the best additive to add to your normal nutes to get the best out of the ones your already using. If your not using it, then HumiBoosta by Hygen is the one I use, and I love it.
So unless you have something like a 600W LED or higher for a 4x4 tent or a minimum of 300W for a 3x3 then its not worth the money on fancy nutes. Save up and buy a stronger light first and stick with cheap nutes and Humic/fluvic Acids to get the most out of them.
