Get a few buckets. Turn them upside down and place them around lamp's radius. Set some of the plants on the buckets so they are above the main canopy. That way, the higher plants get all the light that is escaping from the sides.

Rotate the plants up and down every week or so.
Perp Reviewed by Perp on . help! how can my plants benefit from my HPS, pics! Hi guys, I have a small problem with my plants right now... I started off with 11 plants during my veg cycle, thinking i would get like 5-6 females... just switched the lights to 12/12 about a week ago and now i ended up with 10 out of 11 plants being females!! this is great news but I am having trouble fitting them all comfortably under my 400 HPS. and im worried that they will run out of space as they continue flowering 4 of the plants have been vegging for 2 months and the others Rating: 5
