I was a brand newbie 18 months ago, started with AN's GMB base in Ocean Forest and pulled about 1gpw, over that time I worked my way up to the Grand Master level and saw the representative increases in yield with the same three strains, where I am now consistently pulling at least 1.5gpw dried/trimmed/cured using a MarsHydro TS1000 for each of the 3 plants in my 5'x2.5'x80"tent. I just switched from the GMB base to SensiGrow/Bloom but haven't had a full run yet. For someone brand new I just followed their feeding chart like cooking from a recipe and didn't have to know much about growing or reading the signs, so for me it was worth the premium cost. I've been watering every day, 1/2 from the top and 1/2 from the bottom via the plant drip trays each 5 gal bag sits in, with the recommended nutes per their chart so I could probably drop my costs 50% by watering less, or nuting every other day, but I'm a little nervous about messing with success.
