you can drop the light some as long as the temps are ok at the top of the plants it shouldnt be a problem.
bejay Reviewed by bejay on . Seedlings under an HPS Hey guys, Last time I grew I started my plants out under fluoros but now I have my 1 day old seedlings under a 400w HPS. Do you think this is this going to work out, I mean the HPS is at 1 meter above the seedlings and the temperature is exactly 26°C (79°F) but I was afraid that the light would be too strong for them. Has anyone had any experience with seedlings under an HPS? Could I maybe intensify the light by bringing the HPS down even further as long as I keep the Temp constant? I Rating: 5
