Looking for ways to keep the energy consumption down for a small 1 maybe 2 plant stealth grow... basically I need it to run off of a motorhome style leisure battery. Could probably dedicated 100Ah so ideally 12v power fed LED would be good. 230v+ i'd have to invert which isn't as efficient.
Any ideas what the lowest wattage lighting I could get away with for a decent enough yield, about 2oz total, to last grow to grow.
Thanks
