My first scrog, I had 2 plants under a 2'x4' screen. One sprouted nanners, was a bitch getting it out of the screen. I only do one under a screen now. Here is my second attempt
I live in Ohio. Growing outside here is difficult because the weather is crazy. All over the place. It'll be 70° and sunny one day and 40° and snowy the next so I've never tried.
Im in Canada. I get frost in mid august every year.
I can do auto flower plants outside. Just need to watch the weather all the time. Get them under cover if it gonna be nasty
