Insulating and humidity-proofing shed

I'm looking for some advice on how to go about insulating and humidity-proofing my shed with the hope of going on to turning it in to an indoor tropical rainforest type of thing with pineapples, figs etc and maybe even fish at some point (in Scotland) .

It was a pigeon coop/house and I've cleared it out, redone the outer walls and currently drying it out. I've also bought enough double skin polycarbonate sheet to double layer the 2 window spaces boarded up in the pictures.

Help!?! 29066565_10214474651516339_272659444666466304_o.jpg 29066773_10214474651436337_3356238550633807872_o.jpg 29101120_10214474652156355_7677354771467993088_o.jpg 29133250_10214474651036327_1853720211509739520_o.jpg

Needs lots of light. Are you going to give it a glass roof? Walls? Or daylight-replacement lights like the canabis farms use?

Re insulation, just lots of insulation boards everywhere that isn’t glazed (from seconds & co), not forgetting the floor, and draightproof the door.
If it's going to be that humid and warm I think you'll need to externally insulate it, otherwise you'll risk getting interstitial condensation. You'll need to pay very close attention to thermal bridging, you'll find any thermal bridge will get wet very quickly.
