Oh dear, I hope not. Of course, the sides will roll up but only as far as I have insect screening. Running a few fans for air circulation will be done if necessary. I've read, though, that breezes passing over such a design as mine have a tremendous "sucking" ability, not to mentione the convenient fact that hot air rises. Most desigs that I've seen are of the tunnel type, so mechanical removal of the hot air is a must. So I will have two out of the three necessary items you mention. Fingers…

<p>Most greenhouse ventilation controls are a combination of wind up side curtains (shade cloth screened), stirring fans, and extraction fans (an/or roof vents)...</p>

Hello Cris,<br />
<br />
I sort of made it up after reading everything I could about "tropical greenhouse design" and variations of the same, so you are correct. You also have to take into consideration how the insect screens worsen ventilation. I think it is something like a 30% lessening of ventilation compared to no screens at all. You should check that, though. I would have gone with more insect screen area but I don't want to buy two rolls. If this design works I'll do the same next in Vientiane then…
Hello Cris,<br />

I sort of made it up after reading everything I could about "tropical greenhouse design" and variations of the same, so you are correct. You also have to take into consideration how the insect screens worsen ventilation. I think it is something like a 30% lessening of ventilation compared to no screens at all. You should check that, though. I would have gone with more insect screen area but I don't want to buy two rolls. If this design works I'll do the same next in Vientiane then in Thailand. Same design but much, much more ventilation. Mostly left open at night, I would think. The fish will love the warmer temps so it might be geared more to fish production than veggies. I'm really trying to use locally available, cheap materials. The hoops will just be PVC water pipes with rebar inserted into them for some more rigidity and springiness. Both materials are cheap here. The water pipes are smooth so gentle on the greenhouse plastic. I'm getting high quality greenhouse plastic,as well as good PVC pond lining material for the hydroponic troughs (about 30cm deep). I'm not worried about uv so much as they will have the rafts over them at all times. The divisions between the three troughs will be made with earthbags. Just plain rice bags full of dirt, tamped down, and covered with replaceable burlap bags to protect from sunlight. These can be walked on and are as wide as the usual paths between rice paddy fields, so while I might stumble and fall in my workers should be right at home. The upside down tomatoes might prove a bit of an obstacle, however. I'll keep people posted as to how it works but there will be more details in my normally self-depricating style on my website at <a href="http://www.wrongwayhome.com" target="_blank">www.wrongwayhome.com</a>.<br />
