Hi Oporto and Merry Christmas. I have never made or used Super Soil. I don't have time (or I'm just too lazy), but I'd like to comment on fertilizers in general. Fertilizer is generally sold by NPK (Nitrogen, Phosphorus, Potassium) values in the mix, as a percentage of the whole. So a 7-4-3 fertilizer is 7% Nitrogen, 4% Phosphorus, 3% Potassium. 4-7-6 would be 4% N, 7% P, 6% K. The rest is mostly filler. For vegging cannabis you'd want a higher percentage of N, lower percentages of P and K. In bloom, less N and more P and K. Manufacturers add all kinds of other stuff they'll tell you is necessary, but NPK is the most important. As for your particular fertilizer, it seems to have everything you'd need to grow healthy plants, but the maker doesn't list percentages of NPK or any other ingredients. If you use it, follow instructions exactly... Regarding what seems to be this fertilizer's claim to fame...the crab and lobster shell, which he makes a big deal of...those will give you some long term calcium release. I think when he talks about chitin and killing bugs, etc., he's just saying that the sharp edges of the shell irritate bugs. Generally when trying to keep those sorts of pest at bay one would use diatomaceous earth sprinkled on the plant and/or the soil. So, Oporto, I don't think I'd use this. I would either make a mix using the real Super Soil recipe or I would use a good potting soil/perlite mixture (70/30) and fertilize sparingly with your favorite brand of fertilizers. I grow outdoors, dirt in 10 gallon pots. Seedlings, after they get 2 or 3 leaf sets, I give a small amount of 2-4-2. Veg I use 7-2-2 or 7-4-2 or in that range. Flower I use 2-7-2 or 4-10-7 or similar organic nutes. I don't usually use any supplements. Everyone else I know that grows adds stuff like guano,, mushroom compost and other stuff I can't pronounce or spell. They all have superior yields and giant fat colas that I don't get, but my weed doesn't ever taste like chemicals. One last thing. My wife insists on organic smoke, most of you out there probably use inorganic fertilizers. Inorganic ferts are chemically derived in labs. Organic ferts are derived from natural sources...manure, blood, bone, etc. Hope you found this useful. Have a happy and safe New Year.
