Adding Light and Temperature regulation:
This link shows how to include photoresistors and 10K  thermistors as analog inputs. Using these tools you can regulate the light and temperature of the greenhouse.

  1. Nice project! I’m working on something similar (moisture and timer controlled watering of 10 pepper plants with an Arduino-based board, as well as watering some fruit trees). Have you had any issues with using nails as moisture sensors? I’ve tried a few types of nails, but they all seem to corrode due to light electrolysis or just rust.

    • No problems yet. After how long have you noticed rust forming on your nails?

      • It took about a week before rust was really noticeable, after a couple of weeks one of the nails was really rusted out (the +5v nail, maybe?) while the other nail looked just fine. I was thinking that aluminum tent stakes might work well, although they can’t be soldered to.

    you are using galvanized nails right? also you might try just exposing some length on the end of the wire run to dig into the ground. the copper will corrode but should rust away like an iron nail. means less soldering too.

    • personally I would suggest dipping the nails in flux followed by a tin bath, coating the nails in tin or lead should prevent a build up of insulating oxides, aluminium oxidates quite quickly as well, and its coating is impervious to moisture or oxygen. but if you want to try you can always use a screw connection on the tent pegs.

    hi! my english is not so god , so i will try to do my best.
    first of all congratulation, exelent job!, im trying to do it, but i cant find the sketch, do you shear it or not?

    for the moisture sensor i used another way to do it:

    for the electrolysis problem here are a solution but without slektch
