That's what I was thinking 600 watts and even to save a little money just run hps the whole grow.
Is 67/68 degrees too cold?

I have an extraction fan and carbon filter set up… but not running… because plants were so small… and didn’t think I needed to…

So, was talking about the only fan I was running for circulation.

You want air exchange to happen, I leave my running on a controller 24/7 that ramps the air flow up and down depending on temp and RH.

Good ideA. 128 is pretty affordable. Kind of hard to argue. That give me everything I’d need?

That moves the air around strengthening the stems. Also helps with mold and things like that.

Ballast, bulbs, timer, hangers.
Looks like a complete setup to me.
Being the winter you can run your extraction fan and dump it into the room and it'll warm the basement a little as well. Because you are in the basement you probably have good co2 levels as it is. In the spring/summer I would vent outside.

Yeah I’ll just keep her running. If anything I’m just a little slow on growth. Considering buying a cheap 400w lamp suggested on this thread, and saving LEDS for rest of year.

For a 4x4 tent?

Yes
400 watts will only give you 25 watts per Sq ft for flower
The 600 gives you 37.5.

the metal halide bulb will throw out a ton of heat compared to the hps. you "might" need to dim the MH down depending on your temps in the tents

I think this is the move. These cheap Amazon 600w lamps dim? I’ll check the specs. Thanks for all the insight. I love soaking up all knowledge. I have very little experience. Few grows, a while back.

I’m in upstate NY so it’s cold here during winter. The best bet is to get a 35 dollar ink-bird and set your temp on that so your heater kicks on and off to keep the temp steady. The ink-bird was a game changer for me but I also run a duct off my coal stove so the forced hot air goes directly to my tent intake so my heater barely ever runs. The heater really only runs during lights out just to keep the temp steady.
You can run the HPS light to get more heat but most of that heat will be up above the plants so I still think it’s better to have the small space heater down low so that heat rises and keeps whole tent warm. Just a thought though
