Hiya all,
An acquantance of mine in the mountains of southern Spain asked me this question...
He wants to grow vegetables (carrots, beans etc), as well as capsicums, peppers and some other stuff. He is in a very hot climate, and wanted to know how to protect his seeds from the blazing sun whillst germinating.
He mentioned a polytunnel, and I commented that he could line it with sheeting to further cut down the glare. However, it would get fiendishly hot, even with the doors and 'windows' open. (it can get 40 degrees even in the shade outdoors).
But.. would seeds CARE about the sun, providing that their soil is kept moist ?
(I should point out that we are talking about plantpots/containers here).

Black netting or strips, as they absorb some of the heat before it reaches the plants. They grow capsicums in Spain, thus protected. Get him to ask a local grower.

Ahhh.... right... gotcha. Sooooo.... he could go ahead with his idea of a polytunnel, but then 'clad' it (inside or out) with the black netting ? (and leave the doors/windows open) Would white bedsheets have a similar effect ? I guess we're looking at a simplified version of erani's shade-house ? |

Roofus, he definitely needs an Erani type structure.

OK... thanks for that. Moving on, and all other things being equall, is it possible to grow things like lettuce in these temperatures, assuming appropriate shading and ample water ? Or would the heat kill them, regardless ?

Roofus, if you get the conditions right then you can grow anything, anywhere.  |

I live in phil were the temperature varies from 25-40 at max. All you need is a shadehouse. Dont go for a plastic film, it will just suffocate your plants, ive tried it. We use coconut leaves for the roof, and about 1 meter high bamboo wall.then fine mesh net all over the shade house, it mus be dark in color, i recommend green. If you have a very big area, i recommend installing sprinklers, and water your plants 2x a day. At 40 deg they wont survive if youll just water them in the morning specially if youre growing in containers, i recommend planting tree like plants around your shade house.its very tasky planting in hot regions. But once you achieve a good soil it will be easier, it wont get dried out easily. Never use chemicals, it will dry ur soil. Never leave the area empty. It will make the temperature rise again. Thats how we grow our food. But, our area were not that big. So i dont know if this will help. Hehe
We have almost 20 varieties of sunflower, 20+herbs, salad garden with 5 diff types of lettuce,raddish,carrots,beet, kale, cabbage, diff types of berries etc. More than 50 flowers, and a lot more. Its all in small quantity. But everything we need was there. There were plants thats too hard to grow in our climate but you can grow almost everything.
