I'm looking for a greenhouse for a gift for my wife. This is will be her first greenhouse and I'm thinking of something that is either 6x8 or 6x10. We live in the Philadelphia area, so we have hot summers and cold summers, with snow. I want to spend less than $1,000. I want something that is durable and can withstand the weather. So far, it seems like the greenhouses that have been recommended are the Rion EcoGrow and the Juliana Basic. Any insights, comments, or other suggestions? Thanks.
