Can't give you advice on the HF, but I can tell you if you do a bit of research, there are forums dedicated to HF greenhouses. For many people that own them, they are almost a cult. These folks love to talk about fixing, repairing and improving their HF greenhouses. I'm sure you could get some good advice in one of those forums, not that the two above haven't offered good advice that can work, but you really need to speak with HF owners. It is one of the least expensive, most popular gh's on the market, despite its many flaws, and long-time HF owners have become very adept at keeping it all together and making it work for them.
