yeah .. i’m decent now that i added the heater mats and the temp controllers .. the soil is up around 70 up from 61 and the temp at plant level up to 75 from 65.. the heating mats helped for sure but when they were directly on the tent and the tent on the concrete it was not enough.. i put some foam squares under the liner and just that 1/2 inch of foam insulated well enough and not trying to heat the concrete
