hi meema, my greenhouse is heated too, ive lined the greenhouse around the bottom with bubble wrap, i bought a big roll from focus, wilkinsons should stock it, i have a propergator too, quite a big one, thankfully was given to me, because they are expensive. when i was setting up i went round gardencentres to see if they had any pots,trays. tubs. you"d be surprised how much they have, i know some recycle. but its worth a try it worked for me and ive save quite a lot of money. i grow plants for customers, and i need 6 cell trays or 9s, which i save on my rounds, if your neighbours/friends have bought plants ask them to save the pots.
have fun hope it helps
