i currently have 3 LowRyder #2 plants flowering under 8 42w 2700k clf's in a mini fridge. its getting pretty warm and i was wondering what would happen if i turned on the firdge? would that kill the plants? is there such thing as a timer that would only keep the fridge on when it gets above a certain temperature?
I would rig it as such: fridge to a timer. Find out what works and monitor temps. Try something like 2 min on, 10 off.
Sure, you can run the cooling system to cool off your plants. Keep in mind the cold coil will condense humidity and you may wind up with a pool of condensation in your box over time. The refrigeration system is sealed (unless you have leaks). Running the fridge to a timer will work fine, just be sure you allow 2-3 minutes in between cycles.
i found an online store that sells plug in thermostats for window airconditioners. it will keep the fridge on as long at the temperature goes above 28 degrees. now i just need to find a way to keep the humidity down
