And then, because we cover it with solex, which only transmits 71% of the light, we get to grow cool weather crops like kale and lettuce in intense summer sun. Without it, they just bolt. Permaculture for food is kind of tough in the high desert mountains, unless you live on pinon nuts! And, to reduce water use (a VERY big deal for us), we use Sub-Irrigation Planters (see globalbuckets.org). Really simple, clean, productive, and successful for us so far...

My own limited experience with greenhouses (closed plastic ones) is that they get infested with all kinds of mildew etc. I understand you have to create a healthy environment and give the plants space, but it gets sooooooooooo hot and humid in there................... The companies who sell the greenhouses also sell them together with a "kit" of chemical fertilisers; chemical pest control and GMO seeds, so we have a long way to go!!
Does anyone have any useful tips for me for growing veg in greenhouses a) where it averages 90 - 100+ degrees most days and b) where there is no shade (no trees!). thanks
