Soil, soiless, making ur own super soil and teas? How u plan on growing lst, scrog etc? Lots of variables. But I'd say ud get a good amount if u know what ur doing, and scrog especially with just a CFL. Nice even canapoy and spread to hit the buds. Could get a couple ounces if done right, shouldn't be a problem to achieve .5g/w
I'm hoping for at least .2g per watt from my 500w cfl grow. That would be 100grams for me.. I'm week 4 flower now. .2g per watt for 135w would be 26g but I think you can get more under good conditions
