Quick clone question

Hey ya'll! I received 4 clones about a week and a half ago and was wondering how long I should veg them for? They are under 20 hours of light now. When should I switch to 12/12?

When they are about half as tall as you want the final plants to end up being. They go BOOM when you flip them.

usally about after they are 12'' or so, could you provide more info on your grow set up? maybe some pics of em?

Yeah, in terms of Time Wise there are a lot of varying factors. I grow in water. Took my first plants over 5 weeks to get to the height I wanted them. Now that I have the system dialed, the second batch got to that height in about 2 weeks.

you don't have to wait at all, you can do it anytime you like.

I will get some pics up tonight or tomorrow. They are Headband, Blue Mystic, Cheese, and Ice. All are about a foot tall and have significant new growth since I transplanted them a week and a half ago. I am growing in soil in a 4x4 tent under a 1,000 watt MH. Temps are in the eighties lights on, so a little high, but not bad.

How much height do you have where you are going to flower? That is the determining factor for me. When all is said and done I max out at 3 feet plant height and I mean I am maxed at that.

I have about 5 feet or so.
