My wife and I have been searching forever for a greenhouse that we can use in the mountains of Colorado to grow vegetables year round. We finally found the Juliana Premium greenhouse. It's great EXCEPT it will cost us over $5,000 to purchase! (not in this lifetime!). We continued our search and found the exact same greenhouse design including 10mm twin wall polycarbonate panels, wider doors, the steel base was included and the roof vents (4) came with auto openers. It has a 10 year unconditional warranty on the entire greenhouse and it has a dark green powder coated aluminum frame. Attached to the base are vertical members that will inset into concrete footers which we like as it gets quite windy where we are. Amazingly it is only $2,035.00 Delivered. The only catch seems to be the delivery time which is the first week of March due to so many back orders. Well, if we can save about $3,000 we're willing to wait! Anyway, we don't want to start growing until March anyway. If anyone would like their web address, just let us know. We checked the prices of raw materials used in the Juliana and it only comes up to around $1,400, so someone is making a lot of money at our expense. It's just absurd that they are selling that greenhouse for over $5,000. Anyway, just thought we'd share our experience. We're looking forward to our greenhouse and will post pics as soon as it arrives.
