So I have an 3x3x6 grow tent was wondering what would be the essentials needed when I grab a VIVOSUN 400HPS to ensure it doesn’t get over heated and have high humidity.. I was going to put 4 plants and all of them in 2 gallon pot ..

Make sure you get the sealed hood, a 6" carbon filter and a 6" 400+ cfm fan. Then just use ducting to vent the hot air out of the tent and the room it's in. It will be a tight fit. If you didn't already have the tent I'd say to get a 4 x 4 x 8. But a 400 should be fine in that tent. Shouldn't have any issue getting rid of the heat with a good fan. Run it at night in the summer when it's cooler, etc...

With running with HPS, would my bill be higher ?

IMO I think you might get a little warm in that tent with a hps. Your gonna have to keep the plants pretty low in height with 4 as well. Best wishes grower.

That's why I said the 4 x 4 x 8 would be better. Six feet doesn't give you much room. That's more of a veg tent height.

Your electric bill will not rise a substantial amount. If you know what your rate per KWH is you can get an idea.
For instance, if you pay $0.20 per KWH, a 400w HPS will cost around a nickle per hour. Throw in all the fans, and you might take up another 300w per hour, or .3 KWH...
Making sense?

this is handy to estimate electricity costs. Look on your bill or contact the provider to find out what the cost is per kwh

IMO - No.
A 315w CMH 3000k would be far superior, more light & less heat (doesn't need a hood).

Perfect sense

I started with a 400watt MH/HPS in a 3x3.

Definitely want a air cooled hood and 6” fan. Sucking form carbon filter in tent threw the hood and bulb. Then out the room.

That will get you going. But I would go 600watt over a 400watt. I was never happy with a 400watt.

How much did you yield with your 3x3 400hps?
