Did you throw this plan together on the back of a first class stamp while waiting for your Mrs to finish getting her nails done?
you’ve got a 4x4 tent right?
2x600w is overkill in that tent let alone 3x600w.
then comes the need for suitable extraction.
I can see already major hand holding for this scenario.
who’s giving you all this counter intuitive advice? Is it the guys down the grow shop.
4x4 tent
1x600w HPS or 480w LED.
1x RVK150A1 fan 460m3/h
1x Rhino Pro 600m3/h filter
6” ducting
this is the bare minimum for your tent.
You’ll want to exhaust your air out of the room with the tent In it otherwise you’ll be recirculating already hot air for it to get hotter.
that’s about all I’m giving you for now as the rest you need to go and look at grow room design and building.
