I just got it, haven't gone through winter yet but so far, HELL YES! Even with modifications, accessories etc. which do add up, because the starting price is so low, it made it possible.
I was surfing Garden Web, actually was looking for potting shed info but found greenhouse info instead. I read about the HFGH and ran out and told Bob how cheap they were and that hundreds of people had them around the US and Canada. He asked me if I wanted one for my birthday.
NEVER would he have made that offer if the starting price for the greenhouse alone was $1500 which had been the lowest I could find for a 6 x 8 greenhouse, previously.
YES, almost any $1500 greenhouse is a better greenhouse BUT it would still be at the store!
I've wanted a greenhouse since highschool. (25 years ago, my reunion is next week)
