I'm getting my first ever greenhouse for my birthday next month! It will have to be small, as our upper limit will be around £250, but after careful thought I think it will be polycarbonate. The neighbours all around have toddler boys, and I'm going to need something that will (hopefully) endure repeated accidental football assaults without hitting them or me in the wallet. I don't have the faintest idea yet what to start with, but I have grown tomatoes previously on a window ledge so am hoping to try them next year. Any ideas, tips or suggestions would be very gratefully received. I am ridiculously excited!
