With the weather starting to change in Jerusalem, I need to improvise soon. My plants aren't fruiting as fast as I'd hoped. Basically, I'd like to set up some sort of a miniature green house. I didn't measure my balcony, but, I'd say I've got about 3 1/2 ft width X 7 ft length to work with for 10 plants. The temperature right now is okay, with 60s-70s in the day and 50s in the night, but, I know by the middle of next month it might well dip to near freezing in the nights. I'd prefer to avoid exposing my plants to anything like that. Can anyone recommend me something good for a DIY projec to set this up? I think the most crucial element for this kind of thing would be having a heat sink that can warm the space at night. Preferably a non-electric heat sinks.
Thanks in advance!
