try finding an old sheet of glass, go to garage sales or stores where they recycle house parts from renovation jobs, maybe and older relitive has some older glass without filters.
Chronic Chrissy Reviewed by Chronic Chrissy on . Using glass as a ceiling I was wondering if I could use a rectangle piece of glass to limit the hight the plants can reach to avoid getting burned. I'm planning on putting it 2 inches below the bottom of my 30 watt CFLs. I want to do a SCRoG type method and have the wire a few inches below the glass so I can get maximum light efficiency but not burn. I was wondering if anyone had any advice on my idea. -Dr. Hashman Rating: 5
