Hey cruzer, what's the height between the screen and the cool tube glass? After this run of mine is done I am going scrog and I'm curious to see how much of a shelf I'd create.
Good idea.
As you noticed height is not what you want for a large yield under lights.
What you want is your screen about 10 inches above the center plants curving up on the sides to about 24 inches.
Before you add the screen arrange the pots in the center close together while starting your grow to get the most amount of light. Once they get 13 to 14 inches tall move the plants farther apart leaving a space in the center.
Add the screen at 10" center height and let the plants grow through the screen until they are about 4 or 5 inches above the screen. Thats when ya start training. I always make my bends right before the light goes on. That way the plant has a whole light cycle to get that top to curve up towards the light. If you bend it too far and dont pay attention to this the plant will choose another branch to send the growth hormones to and you lose control. Make sure the tip of the bend is at a 45 not pointing down and the wire or string you use is securing the plant to she screen about halfway up the bend. humm. gonna paint it.
That way to keep the top growing. You can point it in any direction. grow from right to left and left to right to get the max amount of stretch under control.
If you dont the side branches do get larger like SCROG grows are suppose to do but the difference isnt worth losing a main cola.
This is how I do it because if I dont get the stretch I can untie the wire and let it flower closer to the light. Another way is to keep pushing the top under the screen, if you go that route, when you make the bend make sure you have enough stem to thread back up.
