For max effect use 4 foot full service mag ballast and full service cool white 38 watt bulbs. Change bulbs out every 4 months max.
With wattsavors you might want to change bulbs out every month. I tried one once lasted almost 3 weeks, used it hold down the trash can till the trash man picked it up.
But a picture is worth a 1000 words, or 32 clones, 32 prebloomers.

oldsanclem Reviewed by oldsanclem 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
