The time has come that I need to get my heater/swamp cooler for my greenhouse. It's a greenhouse for nepenthes and other tropical plants. I'm hoping to keep it 50F at night in winter and 70F during the day, if possible. When it's 70F outside and there are no clouds (it can get up to 100F in the summer), it can get up to 100F inside the greenhouse. Will a swamp cooler actually help cool the greenhouse down while maintaining humidity? It seems kinda like a long shot... It's a harbor freight 6x8 greenhouse, nothing fancy. I just want something cheap to get to a place where I can keep my nepenthes outside in the greenhouse.
Does this work for a heater?
Anyone have suggestions as to which swamp cooler I should get? Preferably less than $150, but capable of cooling down my greenhouse quickly and efficiently. What do you guys use in your greenhouses?
Oops, also forgot to ask... What thermostat do you guys use in your greenhouses? Looking for something that works well but is not pricey. Just need something that can turn my heater on when the temperature drops before 50F and turn the swamp cooler on when the temperature goes above 85F.
