thats putting a lot of risk on one chance

[celtsbos34]

i have a generator to power everything...someone please tell me how much lighting i should use for this humongous room , 15ft wide 28ft long and 7.5ft tall i know ive read some equation for wattage per sq ft..someone please help

[khronik]

you should have 400 - 600 watts of HID lighting per square meter. one square meter is about 10 square feet.

[celtsbos34]

i was reading that its better to have more lights such as 3 (400w) than 1 (1000w) so i feel like every sq meter i am gonna do 600w
whats the deal with digital ballast? can they use both MH and HPS?

what kind of reflectors should i do to keep the light balanced???

[bejay]

some digital will do both mh and hps and some wont suggest you find out from the manfacturer first, or if your going with 600 guess it really doesnt matter as your stuck with conversion bulbs from what ive seen, and if your planing to use that entire 15 by 28 space you need about 21000 watts of hid lighting hope that generators a big one.
the 1000 watt light is your best light for intensity and if you was going to grow large plants for max yield would pobably use 1000 watt lights.
it is a big investment and big risk for one grow but if you have decent luck with germination you could easily have 50 females from 100 seeds and could veg for 2-3 months and put 4 large female plants under each light obviosly you will not have enough plants or lights to even come close to using the entire space.

[jamstigator]

At one 600 watt light per square meter, if you used that entire space up for flowering, you'd need 42 600-watt lights, and a ginormous generator. Or a majority share in your nearest nuclear plant.

Do you have any natural gas or propane appliances in your basement by any chance? If so, these can help boost your CO2. For instance, you can get a gas hot water heater to vent directly into the basement. A furnace, though, would use way too much oxygen to be able to vent that straight into your basement.

This is idiotic advice!!!

Do not ever vent any gas appliance anywhere other than to outside. Carbon Monoxice is a by product of combustion and it will kill you!

Venting gas appliances to the inside of your house will kill you!!!

Jeez, Khronic, get your head out of your ass and think before you post something like this. Bad grow advice can only ruin someone's crop. This kind of shit will get someone dead!

ive only seen the switchable ballast in 400 and 1000 w lights but i havnt shoped around too much. i originally wanted to do 600s too but decided on a 400 switchable first then when i can afford it get a couple of 600s hps(ive seen a ballast that can run 2 600s) and use the 400 for veg. obviously you are thinking much larger. good luck but as some one said all of those lights will be hotter than your ac can handle. and to vent that large of an area you will need some very powerfull fans.(noise) obviously you wont be covering every square foot of floor with lighting either. best i can think of is to do some figuring and section off an area that will handle the space for your lights. then cool that area and keep your ballast and heat generating appliances out of the grow area and vent into that part of the basement. a plus lol you might heat your house with your lights.

Natural gas/LP is used to produce CO2 in GREENHOUSES.
NEVER EVER attempt to do this in an occupied building.

Furthermore, this thread is getting weirder than weird-
You are trying to run a giant cash-crop cycle and then move?
Honestly the questions you are asking are making me think you don'thave anywhere near the expertise or experience to pull off something like this.
Start small.
Remember the parable about the greedy crow who gets his head stuck in the urn because he refuses to drop the GIANT mouthful of grapes?
You're biting off more than I think you are prepared to chew.
