So basically putting a good heating pad and foaming the floor under my tent would help me keep temp in check during “night”.Also,I was thinking of skipping this process because I have autos and give Them 20 light.It would cost me less Electric Bill wise to run 22 or 24 hours light or giving 4 hours of darkness rest without any heating help,BUT,It would drop the humidity to 80 though.That Is my dilemma.4 plants in 2 gallon fabric pots and humidity goes to the stars when light goes off.Maybe I should buy a very big Dehumifier,but It Will cost more…Dilemma intensifies…

Solid point, so then this setup should work being that the fixtures are rated for max 150watt and the bulbs are 100watt right?

Experimentation is key as each environment has so many factors.
Y’all are doing solid research and your follow ups sound rational 
One reason i’m setting up a new 2x4 is to have a 24/0 veg and auto tent that will also act as a heater

perfect! I have 3 of those and one 200 watt bulb. I have 2 that have an adjustable dial, the others are just on switches. The adjustable ones are way better for dialing back the heat like this one in my small 18” x 36” veg tent. The fixtures I bought at Lowe’s for like $12 and the bulbs from Amazon for $8-$12

Totally agree about the heat mats. The ceramic heaters work very well in tandem with the heat mats. Plants love the warmth of the soil as well as the air. I get away with a lizard heater at 100 watts and two 17 watt heat mats. I pull the intake air across the top of my light and driver to warm the cool incoming air and simultaneously cool the light and driver. Exhaust pulls from mid tent oriented as far away from the heat mats and ceramic heater as possible. This is for a 2x2 in an unheated attic which gets down to mid to low 50’s. Tent on the inkbird is 78-82 lights on and will get down to ~69 at lights out.

Nice setup,thinking of buying either 100 watt ceramic reprile heater or a big Dehumifier,I don’t know yet

Any chance you could link to the fixtures you got from lowes? $12 sounds pretty good compare to $41 for two of em if they’re the right build/wattage

Let me check that out Brother.

My mistake on purchasing these from Lowe’s, confused those with clamp light I have 60 watt grow lights in for shelf plants. Here is the one I like, have 2 of these and the dial works great sorry, I’m technically challenged on links.

This has great fail safe.
Hardly ever comes on. I just lost heat for 2 very cold days. I was really worried about the plant. When I crawled out of my cocoon and went to check that little guy had keeped the whole M-I-L apartment a toasty 70.

How cold is it out side your tent. I like that. I was looking at them. They are cheap. How big is your tent. I got to get back into mine. I’m getting overwhelmed in this tight space. I’m staying warm. They are happy. But it is very tight.

My garage/lung room I have insulated and dry walled and 2 small floor heaters beside the tents that help keep my temps in range when’s it’s lights on. Lights off and super cold outside temps of 25 and below have my lung room at 59. The reptile heaters have my tent and closet temps at 74 lights off. I’m running autos and photos so opening the tent to make adjustments in the photo tent can get tricky especially if you’re at work. I use the heaters with the dial and adjust/play with that setting for the lights out temp difference and it’s on a timer for the lights out colder temps. Hope that helps a little

What I can see wrong with those hanging heater other having seen them fall and burn up barn. Is Heat rises and the heat would go up where you don’t need it. Also, it is the roots that really don’t like cold feet. They just seem counterproductive to me. jmho

thats a solid point, i find myself feeling different every day about the options, really the biggest benefit i see to the hanging heaters is that they dont take up floor space, could potentiall drop them down to be right on top of the canopy, under the light, but you’re right that they probably wont help to root zone as much as it would if there was a nice radiant heat level with the pots. so many things to consider here.
My assumption from using them in other situations is placement. If hung low and inline to a fan blowing down (or) an active air intake then the radiant heat should get dispersed and avoid the hot spots + top-o-the-tent heat pooling.
It’s a variation of why my heater is outside of the tent, with a fan drawing the hot air INTO the confined space. (this and also both my 2x4 and 4x4 are drawing heat from it.
THOUGHT: Make a “heated lung box”. An enclosed space built with the intention of holding these units with forced air out feeding the tent(s).
