I have feedback... you have stumbled upon a rule of 2-room systems.... Three times the watts and space that you used in VEG should be used in FLOWER for high efficiency! :thumbsup: Nice call on the switch from 2:2 to 1:3.

I also think your extra veg time idea is good. Remember if you aren't doing this already, cover the 2-liter bottles with tinfoil or black spray paint. Roots that are exposed to light both function poorly and I suspect may not 'take off' quickly after a transplant.
