I'd rather stick with the MH versus the HPS. Lumens is a humen-eye measurement weighted at 555nm and means nothing to plants. The MH is much closer to sunlight and offers far more PAR PPFD than an HPS ever could.
khyberkitsune Reviewed by khyberkitsune on . Is it time to force flower yet??? Unknown Indica looking strain. It is 20 inchs tall and has decent growth. Growing under flouresents. Might be female, has 2 whispy looking hairs on side of each stalk next to leaf branch growths. (expand pictures) Has been 24/7 lights for 5 weeks. Wondering if its time to turn off the lights and flower? Thank you. Rating: 5
