Hey Q dude! Looks like you’ve got a nice place of business there.
The main problem I’ve seen with greenhouse grows in the uk is bud rot due to humidity. I’ve known peeps to rig up PC fans to car batteries to blow a bit of air around, but that’s not a problem yet.
I like to do mine totally al fresco. They get wet but the air circulation sorts it pretty well. Used to grow them in my back garden until some friendly police officers moved in next door, then I had to go guerrilla styleee!
Best of luck with the grow bud, I’ll tag along if I may...
