Thank you for the link with the tips, good stuff!

Yes, good eye noticing the stretching. It seems rather hard to avoid for me. I can raise the plants with my 3D printed stackable containers, but too close to the lights will burn them. I have to run some experiments I think :D

A good counter method to stretching is the pin down method.

Maybe I will make a post on that..

A continually pinned down stretched plant will open up the nodes to more light exposure (good), and will maintain a low profile for the tent. It's also super cool looking when releasing the pin downs during flowering. It looks like a spiraled bonsai of sorts.
