HandyTecanswered grow question 5 years ago I have been experimenting with everything I had available to me. Even picked up a large cardboard box (free) from a furniture display item at Costco. Dried inside the cardboard box with just a small fan inside and lifted it up once a day at night to get an air exchange. I know, really low tech but it worked.
Then I built a 4x4 (tent) out of some pvc pipe and some 1" insulation panels I picked up at Lowes then made a door from some faux leather upholstery material from the fabric store and stuck it all together with duct tape. A small hygrometer and a small oscillating fan. Not beautiful, but the best drying space ever! (also works for the baby clones as it is really humidity controlled.
Your setup looks good to me.
