Hydroponics in cold weather?
I was wondering if anyone could provide some insight on growing hydroponically in an unheated garage in NJ.
The garage is attached to my home on 2 sides and the basement is somewhat heated so there is some warmth lost to the garage.
With addition of a 1000 watt MH lamp, I am sure that it will not get below freezing, however I wouldn't count on anything much above the high 30s. I could also heat the space with a cheap unvented natural gas heater but this brings up moisture concerns among other things.
For lighting, I do not plan on skimping. I was thinking a 1000 watt MH lamp covering a relatively small area of about 16 sq ft (Is this overkill? It's about 62 watts per square foot) on a AeroFlo 36 Aeroponic System (or something similar?).
Can I grow anything such as claytonia, kale, arugula, spinach, or a hardy lettuce WELL under these conditions (fair amount of light, not a lot of heat). If so, what sort of yield could be expected assuming proper nutrients.
I do not plan on re-selling, but consuming and giving away the rest to friends/family. I know lighting bill on 1000 watts * 16 hours a day will cost me $90 a month so this has to be considered.
Any recommendations on different lights or systems?
