    Heating outdoor greenhouses

    My terrarium is getting to look very small, so now I am planning on making a PVC greenhouse. The weather in my area is pretty mild year round, with lows at night in the lower 40's and highs in the low 90's. I wanted to make a lowland greenhouse outside for my collection, and have solved everything but this:
    Where will I get outlets?
    My dad says the outdoor outlets are all 24v AC, much too low for my purposes. I will be hooking up at least 3 humidifiers, plus a heater, and possibly some kinfd of house fan. I thought I could run a power strip inside the greenhouse and hook it up to the outdoor outlets, but the low voltage is going to be a problem. How should I go about this?

    I would get a licensed electrition to run a main line into the greenhouse from your home's panel. (If you have the capacity remaining for it)

    I'm in agreement with boxofrain on this: do it right, and hire an electrician.

    Just a thought: can you run a quality extention cord from a higher volt outlet inside the house (if you have one)? Otherwise, an electrician is probably a good idea.

    I personally would also look into other methods not requiring electricity. For example, raise humidity using several trays of water and half submerged rocks (which increases evaporation rate), and/or hosing down the floor of the greenhouse a couple times a day. I personally couldn't stand the thought of running humidifiers all the time and always having to refill them. But maybe that's just me

    Although there may be a outlet nearby, I'd go with what everyone else says and hire an electrician to see to it. You wouldn't want the outlet to short out on a below 30*F night.


    In addition to growing plants, I design and build RC planes powered by Tesla batteries. Check out my progress at www.chargedplanes.com

    I would consult with some other folks w/ greenhouses in your area (ie: Brokken), I suspect (& may be wrong) that the amount of heat required to keep a greenhouse in LL conditions is quite significant.

    I need a heater at night because I need really warm temps. About 30* higher than outside the greenhouse.
    I can't hire an electrician because that would cost cash, and i have to pay for it. I can't afford to splurge $300 on an electrician job.
