Going Vertical: Construction of a Monster

hey what do you use for medium by the way?

hydroton or rockwool, but anything can be used

Hey there FLoJo Id just like to ask what type of wood planks did you use? It looks like pine.
Also how did you manage to keep the setup stable? By looking at your pics you didnt mount the frame on to a wall.

Lastly how did you find the sweet spot distance of where to place the plants for best penetration without burning them in early flowering?
