Hi Guys, I'd like to invest in a hot house to grow my seedlings. I've been using a 4 foot flouro light propped up on bricks and covering the pots with gladwrap until the seeds germinate, then in a few weeks time moving them to a cheap $60 plastic greenhouse that's about 2' x 1.5' x 5' high. This is really impractical and is really holding me back! I'd like to buy a decent sized hot house where I can grow enough seedlings to plant up my 1/4 - 1 acre! I have no idea on prices or where to look. What are the size, lifespan and practical differences between plastic or glass? I'm in Vic. Cheers!
