You could be looking at it all wrong.
Having high ceilings is way better than not high enough.
You have options.
Perhaps look into vertical growing.
Grow em nice n tall around a cage with a light or two hanging in the center.
i do not want to grow vertical as i do not want to experiment i want to crop! lol would it is very hard to find threads about indoor soil with high ceilings
You don't have to do vertical!
It was a suggestion, u won't find many people complaining about to high of a grow area because most people would rather a high ceiling then a low one.
Just run longer chains or yoyos and grow regularly.
The extra height is helpful for getting the excess heat away from the ladies.
