I've used a cheap 2x4 foot by 5 foot high grow chamber,you know those that have a silver reflective surface on the inside and are black on the outside. I used 5 cxb 3590 led COB lights along with a thermostat to keep the air temperature in the correct range inside the grow chamber, I grew 2 indeterminate plants of which the largest tomato was just under 4 lbs. The whole tent was set on top of a 2x4 foot by 16inches deep insulated box that was also thermostatic controlled with a heat cable wrapped around the interior of the box,that way I could keep the soil temp at an ideal level. I don't know if any of this will be of any help to you or not, just sharing my experience with you in case there's something that might give you an idea.
