I am going to purchase a greenhouse this year, but I am debating which way to go. Of course like all people, at least us common folks, money is quite an issue. I have been following the HFGH readings and I am impressed about the modifications and low cost of the initial unit. Yes, I have read about the couple,and I do mean couple of bad reviews that the unit has gotten, but there is a lot more positive reviews. I have noticed that the unit is now around $700, so it must be getting popular. The way I have it figured is that even at the new price, you could probably have a good GH set up for around $1500. That would include heater, vents, openers, venilation, etc. That wouldn't include the foundation, wireing, plumbing, etc. Now the other unit that is reasonably priced, Ha, is the Rion unit. I haven't found alot of negative about it, except for one really bad post on it being made out of plastic. The plastic is the part that bothers me. I have some plastic resin figurines in the garden area that are starting to look really cra--y after a couple of years and I am thinking that the same thing will happen to the Rion. Most of the post on it are from people who have just set thier up and how pretty it looks, but what about three years down the road.
Also, with either one of these units, is it feasible to do a cinder block wall 32" tall (four blocks) and then set the GH ontop of it. I think that it would look better, and it would protect the panels from flying projectiles set free by the weed eater or lawnmower.
