Is a 600 watt HPS/MH enough for a 4x4.

Question for vertical lighting experts.

I have a 4x4 tent that I intend to line the walls of with vegetables. Tomatoes, cucumbers, strawberries, lettuce, and various herbs are planned right now. My question is if I would be able to get away with one bare 600 watt HPS or MH bulb hung vertically? I want to keep my heat and power consumption low, as this will be in my living room.

Thanks in advance.

Hi bicit,
I had questions about a similar setup. I´m sure the vertical pros on this forum are willing to help you. Until they do I think you could find some help in these two great threads:

Good luck!

Should work splendidly. Heat may be another issue it will need some type of exhaust for sure.

I have a 6" fan and a speed controller, no worries there. I'm mostly worried about heating the house up too much as we go into spring and summer.

I use the exhaust from my 1000w to heat my entire upstairs of my house.
In the warmer months I will certainly have to vent it into the attic - I don't want to vent it outside due to heat signatures.
Venting into the living room will raise the temperature, no doubt about it.

I use a 6" fan for my 1200w 4x4 vertical set-up and have for years. 600w will be perfect.
