for 8 square feet of grow area you would need about six 3070 cobs

The Vero 18 3500k at 700ma outputs ~2600 lumens. 15 of them makes ~39000 lumens. That's ~130 lumens/watt. Around 300w total for a light far better than a 400w HPS.
I am using 15 Vero 18s over 2x3 ft. They are usually dimmed to about 500ma. I also run my light about 5" off the canopy and use a mover. At 700ma I would want 10 in my space. Here's a picture of the light in it's early form. Now it has Meanwell HLG series dimmable drivers and the emitters between the Veros have been replaced with Cree XPLs.

I know your problem. I have the exhaust often off because there is too little heat in my growroom, otherwise I run the exhoust very low like you. Could you isolate your room more? A tent does not isolate very much. Maybe wrap it up in styrofoam to keap the cold outside the tent.

I didn't even think of that! I could probably try that I'd lose my reflection Mylar that's in my tent now but I could try the foam that has that on it too.
Hello nvhak49. I grow in a 4 x 2 space and I use 8 vero 29s. I drive them using the 50w ebay drivers. Grab them while you can. They sell out like hotcakes.

to keep the heat in my room, i use a thermostat to control my exhaust fan. it only turns on at 72F.
