Is this the same as Bubblelicous? They look great.
One thing that confuses me though, is that you said you just switched to 12/12, but the plants are already flowering...??? Or did you just recently switch out the MH bulb for the HPS?
I've had the light close enough & the grow space is a budbox 75x75, im using an ordinary pc fan for outake and desktop fan for intake, im using canna coco nutes & growing medium.
ahh, your fans are weaker. im using the stanley squirrel box fan to run my cool tube, which is a little noisy, but with the fan also in the veg area circulating, i can put my lights closer...
