Better, yes, but some folks grow all the way through using just an HPS light. If I have one to spare, I throw it on vegging plants too (along with some blue CFLs), and while the HPS light isn't optimal for veg, it still helps some. I've got 10 clones growing under eight blue CFLs plus a 400w HPS light at the moment, and they appreciate the extra lumens, even if it's redder than they need at the moment.
jamstigator Reviewed by jamstigator on . Ventilation for veg/clone chamber in grow cab I've built a grow cab that is 7x4x4 and have allocated 2ft of space for the veg/clone/mother section and 5ft for the flower. I have a 600w hps with a cooltube and will use a 6 in inline fan expelling air throught the carbon scrubber. I was thinking about adding another 6in inline on the opposite side of the cab with an additional scrubber. is this overkill? My main concern is getting fresh air into the whole cab. Any recommendations on how I do that considering the flower and veg Rating: 5
