I know this is an old thread but i grow with CFL (autos only) and get good results.
I have just started my 6th grow.
Grow number 4 was 4 x DP StarRyder, using 2L pots and organic compost/nutes.
The CFL i use is a Plug and Grow, 250 watts (real power use 190-200), red spectrum, 19,500 lumens.
Cabinet is DIY 2x2x3 feet high, 4,750 lumens per square foot and 78 lumens per watt.
I got 4oz, 3oz of main buds plus 1 of small stuff :
The only problem i have is lack of potency.
From a single harvest, some buds will knock me for six and other won't have any effect at all.
The only strain i've grown that is consistently strong is AKR.
My growbox is low humidity, i made it from chipboard (which sucks moisture).
Anyone know much about CFL/Auto and potency ?
Cheers,
nibs.
