About a foot, two at the most (maybe a bit more for seedlings)
The light is about 20 inches from the tallest plant. How many plants can you scrog in a 2foot X 4 foot screen?
how long would vegging be on 4 plant scrog about 5-6 weeks?
Thanks for the info. This hole grow they are going to stretch because my light isn't fully adjustable. Was thinking about scrapping them and doing the light correctly and start over. Don't want to waste another 2 months on flowering if it is nothing but a waste of time.
Plants are stretching like crazy. Have 3 plants over 30 inches tall. Hope to start seeing male plants soon so I can get some room in there. Let me know how they are looking to you guys.
Has anyone tried the CMH lights for flowering? http://advancedtechlighting.com/cdmed18.htm
Yep, I have one of the Philips CMH's. Its the 250w, 4000k temp. It works great. It's one of my side projects, you can see in my pic album or journal. Been growing great, seems to have a lil less stretch then the HPS...and if you run it in an open hood, you get some UVB on the plants too, which is supposed to help increase thc output in trichomes. Based on the fact that equatorial sativas typically have higher thc content, equitor = high uvb. Anyhow, biggest they come is 400w...and they run on HPS ballasts. Got my 250 for about $60.
