So im hoping this is a good place to write a quick review about a new product most people haven't herd of yet. I herd about it from my buddy that's owns my local supply store. I walked in and he asked me if I have ever herd of GT. I hadn't at that point but I have a thing with him where I try to test anything I can before he makes a large supply order. First of this shit so far is awesome. The product is supposed to replace all additives so that you use only base nutrients and raise PPM to 1300 then add GT. It is not yet OMRI certified but I was told from their rep that they are in the process of getting it certified. This stuff smells awesome too like molasses. It is derived from Potassium Sulfate with lots of good stuff in it. NPK ratio is 0-0-2.25 but it makes a big difference with greening up your ladies. Mixing ratio is 2ml/gl during veg and 5ml/gl during bloom. One of the biggest things I noticed was how my leaved stand straight out nice and perky. we all like our ladies being perky right? haha I was skeptical at first but after about 5-6 days using it twice I started noticing changes for the better. I am using it both with just base nutes and also with nutrients but cutting back additives like voodoo piranha etc I have not used it late into bloom so far as I am only in about 3 weeks with some of them. I am using it in both my soiless mix and DWC. In DWC the only thing I don't like is the root staining from the molasses but no big deal. I noticed a big jump in new vegative growth with it also. I will keep updating my experience with this product but as of right now I would recommend it to anyone with any style of growing. I got a gallon of it for 260.00 usd and it goes a long ways especially if you was to eliminate all additives that's a lot fo cash saved. I posted a link below to check their site out and they also will send you a free sample bottle ''about 100ml''. I ordered a sample and gallon and they got to me in 4 days. Great customer service and fast shipping was a plus. They also do bulk discounts too.. Here is the link http://humboldtssecret.com/ if you want to ask more ?'s about my experience with it just ask away and I will tell you what I can but like I said its new to me until I complete a grow with it. On a side note I am running Advanced Nutrients with it but also running GH in hydro with it both with great results....
