1800 watts in 4x4x7 tent???

research all you want. expirence is what really matters. thats where you get real answers genius.

only using 1400 watts. have 1000 in the middle with a mh on both sides slanted downwards. one mh goes for 6hours and then the other for the last 6 hours.

i run a 6'' air cooled 1000w hps in a 4.5x4.5x7.5 tent and i get some really nice buds.
The tent gets about 8 to 10 degrees hotter then the intake air temps,so my temps are between 78 and 85 through the summer, alot more stable in the winter.
i think 1800 would be too much for a 4x4x7 tent

but what about 1400?

Someone with experience need not ask stupid questions. You're right again, what good would research do? Cart, then horse, right? My grows are out of your league, and not flights of fantasy. Prayer may do more for your plants than you will.

Pics or this shit never happened sorry to say. I mean seriously you've asked a pretty outlandish question, and ok you've gotten some pretty outlandish answers, but no need to abuse the people trying to help you out or even just stating their opinion like duder, which wasn't that offensive anyway so just relax.
4x4 is my tent specs, and I run a single 600w mh/hps in there with minor heat issues over the summer if it's a really hot day. You're adding 1200W to the equation?? (not to mention you haven't stated whether they're in reflectors/air cooled hoods?) and even if they weren't, there's NO WAY you have space for 3 lights, a 12 spot ENF, a "air cooler"(whatever that may be?) and sufficient amount of air induction in there buddy have a good one.

You'll need more than just a chiller with that much wattage going into that little tent. You're gonna need to pump air conditioning into there as well...

Don't think it's gonna happen regardless.

All you need is a 600. You aren't trying to mimic the sun as you will fail every time. You are trying to maximum both yield and efficiency and 1800w over a 4x4 is not at all efficient and IMO will likely lower yield due to stresses. Like people have mentioned it's definitely possible but that doesn't mean it's a good idea nor that it calculates out $/g.

Here's a 600w tent yielding ~1.2lbs a swing with low veg time. I can't imagine you yielding >3.5lbs in a 4x4 (the equivalent weight/wattage). Flowamasta's Grow No.3 indica clone-harvest grow Journal! 1 PLANT!!! 600wattHPS
