Cogo's Original Cannabis Formula is so pure, I am in disbelief still. I've only been growing for a year, and using Cogo's has been my best move. My last grow I decided to "push" the plants a little. I monitored my PPM and increased by 50PPM each watering. By the last week of flower My plant was up to 3000 PPM. NO Burn, and the results were incredible!! 38 Ounce Harvest!! 1 Plant, 1 Light (i did us a T8 as supplemental lighting) Thank you Mr. Cogo for your incredible product.

As novice growers, we were suckered in by all the expensive nutrients sold in the grow shops. The balance of chemicals, water, time, headaches and expensive made growing ANYTHING a pain. With COGO, everything is simple! There are only two simple and inexpensive nutrients to mix with any water, even well water (we were running our R.O. system dry, as well as the R.O. system at the local grocery store), adjust your PH level and you are ready to make miracles happen! "COGO SAYS GROW" is the saying around our garden when we look at our healthy, strong and robust plants. From bud to growth to flowering to harvest...COGO works! To all you novice researchers of plant nutrients, if you know about COGO and still try the other nutrients, you are throwing money and time down the drain. It is simple...It works better than anything else we have tried and we tried just about everything. COGO SAYS GROW!!!

This nutrient is hands down the best for cannabis as well as other herbs and veggies but by far no other company can give me cannabis cup quality and results in there product. Not to mention the money saved now that I am not polluting my water with coslty ineffective additives, and inferior not “Ionic” availability. It has kept my hydro equipment very clean, and kept my garden even happier, fully letting the garden complete the kreb cycle. The aroma, of vegging garden is stronger than dispenary med jars. NO BULLSHIT. Only crap is in the cheaply made nutrient lines out there, and the overpriced hydroponic stores. I have been a do it my self kinda guy and what cogo’s cannabis formula does for my plants even I can’ not duplicate with any other product out there than Cogo’s. So thanks for taking the mixing headaches away, and giving a product that is better than ever expected. Sincerely, Brodie

Simply amazing!!! My Plants are four to five times bigger than the plants I cloned them from using techna flora nutrients. No ten to twelve bottles of junk to mix. My tanks are very very clean!!! :) And the tomatoes that I fertilize with the waste water from the water changes are already five foot tall first day of summer. Thank you!
