So I began my R&D with GHSC Powder Feeding. I have started 4 Green Crack and 4 Tranquil Elephantizer, a privately developed strain using only Hybrid and chealated Calcium. I have only just put them into the veg room so to date, I have nothing to report. I am photo/video documenting my results for use at my Hydroponic supply store . This way I can confidently recommend these products to my customers. Here's hoping the hype surrounding these nutes are factual.
