1800 watts in 4x4x7 tent???
is 1000 watts of hps and 2 400 watt mh too much light for a 4x4x7 tent set up with ebb and flow 4x4 table with 12 plants? was considering running the 1000 hps and one mh for 6 hours then switch to the other 400mh for the other 6 hours? i have just heard talk of having to much light on plants being possible.. thankx.
If u believe that shit, you will believe anything.

600 dosent seem like it would be enough. that is only 37.5 watts per sf when 50 is what everyone says you want.

Waaaaay too much. 1000w would be perfect, assuming you can keep the tent and lights cool enough. You might be surprised how much effort it takes to cool a 1000 watt lamp in a 4x4 tent. Cool intake air and air cooled circuit for lighting will be a must.
4x4 - 1000 watt
3x3 - 600 watt
2x2 - 400 watt
In general... You can cover a little more space if you want. Especially if you are less worried about getting dense buds, and more worried about high yields.

It works like a vaporizer. We'll get stoned through the vents on the way there.
Not in your wildest dreams would all those work in a small tent. I laugh at the thought. Everyone likes fantasy, but stay inside the practical. What a question....

you can def do it.. i have a 4x8 tent which i normally run one lite on each side.. but since im staggering each side by 4 weeks (harvest every month) i temporarily set up my tent with both 1000's on the same side and im have great results.. ive lowered one ballast to 750w and running the other at 1k (adjustable ballasts) bc its summer and my room creeps over 85 with both lights at 1k.. but that is something that can be fixed with a bigger A/C... as long as you can cool it, go for it. you can light bleach the top of the plants if the reflectors are too close ..but no probs with that here. in fact.. unless you have a really large reflector the corners of a 4x4 tent wont recieve all the light they need.

well shows what you know because they seem to work just fine in there. heat is not an issue because i have a water chiller.

that last one was to the dudoer. i mean how much is the sun producing? tryin to get as close to the sun as possible, rite?

Wow. 110 watts/sq ft. You are pulling it off. Is it efficient?
It still is 1750 watts in a 4x8. Even though it is moved to a side, your enclosed space is 4x8.
OP is talking about 1800 in a 4x4.
If the chiller will control it though, do it. Would be sweet to see.
Efficiency is only part of the puzzle, imo.
Amazing buds are what drops jaws.
from my book understanding, not experience, you might need co2 to reach potential.
even then, you be getting diminished returns on your wattage.

You're right, I know nothing. Try research over stupid questions; maybe you'd get better answers if the questions were worth reading. Good luck, you need it.
