  1. Thank you for this information! I’m hoping to start growing some vegetables in my house and found this very helpful.
    I might be limited to a radiator shelf for the vegetables though and am wondering if the extra heat would be damaging to them. The radiator is directly beneath a window that gets lot of good light, but it’s a big radiator. If I used a humidity tray do you think that would help the vegetable plants tolerate the heat? Or should I just avoid growing veggies over a radiator completely?
    Thanks again for your advice!
