I have ph and ec meters and four 15 liter buckets, the two plants I have growing are keep in 22 c temps. Any lower my electric bill would cost well over $100 US.I would suggest one regular or feminized strain, topped in a 20 liter water bucket and terra aquatics trio fertilizer if your water ec is low enough and you would buy a ph and ec meter and you can control temperature betwen 18 and 22 degree or two to three 15 liter buckets for soil. Your light is great in my opinion.
