I have maybe 6" above my tent but can't really do anything due to a ceiling fan. So its stuck where it is for now. Not much I can do with that 4x4 tent in the spare room with the bed in it LOL.
Honestly I don't spend much time at all in the flower tent. When the plants go in there, most of my work is all done other than a defoliation after about 3 weeks and watering them. Most of my tinkering is in the veg area. I have some thoughts in my head of grow shelves that I can pull out that will raise up.
My dad is a former NASA engineer and can build anything. He is coming out in a couple weeks and I am going to run my ideas by him and see what he can come up with for a plan. Essentially when I pull the shelf out....I will either raise it or lower it (my idea has two levels.....so the top level would come up, then out, and then down to about waist level. For the bottom level, it would come out and then up to about waist level. When I get done watering and training, I just drop it right back down under its lights.
