Light distance and wattage.

Discussion in 'Growing Marijuana Indoors' started by Clinton Kong, Jul 15, 2017.

  1. Hello all! Hope you're having a good weekend? Got my 4 critical Kush (3 weeks old) and 1 sour diesel (two weeks old). Transplanted into bigger pots today and change from CFL to hps. Is 600w too much straight away? Also I know the light is too far away in the picture. Will be moving it tomorrow.....what distance would you guys recommend? Thanks in advance[​IMG][​IMG][​IMG][​IMG]

  2. My light (600 HPS) is probably 14-18" above canopy. Just set your hand on the top of the tallest plant and feel how hot it is.

  3. 14" will be good. Lowered the the light earlier then went to my girlfriend's for a few hours then come back to check temps. Tent had positive pressure, when I opened to tent I had realised I had split the ducting when I lowered the light. Will definitely be getting some better ducting
