Hello I have a grow room in a basement whit 2 hps 600w each one.
I had one cycle whit 20 plants (21days veg), I use advanced every time I give water to my plants, is it right?
The result was 500g in total and I use 1200w
The temperatures was like 24/28 grade Celsius, but I only had one air extractor (1000m3) maybe for this the result was not 1g/w?
Now I have 10 plants in veg(10 days) under one cfl 250w, and I plan to use only one lamp HPS 600w and I add one air extractor for the entrance of air that goes evry 15 min while the other is not going

For fertilizer, go by what the nute manufacturer says to do. They've done the research as far as what gives the best results.
