Jam, The Huts are not hard to put together, it just took me awhile because I had ordered a whole bunch of new grow gear and I was playing with it along the way. You'll get it up in an hour or two I'm sure.

One thing I am a little worried about though is that the passive air intakes are not completely light proof, particularly not during the day (which is the dark period for me since I like to run the lights at night to balance the temperature variations. I'll be looking at ways of addressing that - maybe fishing weights on the flaps??

BlueBear: thanks for your comments too!! I don't mean to only chat up with Jam, but he is going to run a hydrohut too and wondered about his experience with it. I've read a lot of your threads and you dispense great advice and creative solutions!!
