What kind of hood? Be careful w/ MH bulbs. I don't even use em. Yes, the spectrum is better for veg, but what you lose in spectrum, you gain in lumens w/hps. For mothers, I use an 8 bulb t5, then (if I'm gonna veg at all, I'll go w/hps).
Here's my one plant scrog still early in flower. I know the real cut of Chocolate Diesel is pretty much impossible to get anymore, but I can't say enough about it. Check it in a 1 plant scrog under a 600 41/2 x 41/2. If I don't pull over 1.25 gpw, I'll be shocked.
Chocolate D is the good pt of GG#4. I can only tell the difference in the yield w/choc.
Send a pic or 2. Wanna see how she's coming along, and see if I have any suggestions for ya.
