wat size and how many lights would u guys go with for a 10 x 12 room??? im trying to get max yield in this room!!!!! i just want some ideas from all you fellow growers
thanks
thanks

ya ive read around and see alot of people using 600's thats why i started this thread! so how do u think 4 600's would compare to 4 1000's???
im gonna be getting 2 8inch eclipse fans (around 750cfm) ea.

This will translate into about 300-400 dollars a month increase in your electric costs.
Is your electric company going to ignore this jump in usage?

Rolling Thunder said:A few things: First off, the best European and Aussie growers average a 1.5 lb to 2.0 lb yield per square metre, using 600w HPS bulbs; and that`s using HPS from veg to flower, and no MH`s. Some will supplement with UVB in the latter stage of flowering. That is the real bench mark, in my opinion. As someone else observed, the 600w HPS bulb is the most efficient bulb, bar none. That means you get more bang for the buck, in terms of your electricity.
The second thing is, the most limiting growth factor in most good or well-run indoor gardens is not the light, but the C02 which drives photosynthesis. You cannot maximize the full yield potential of a 600w HPS bulb without C02 supplementation. If that is true of the 600w bulb, it is even more so true of the 1000w bulb.
The average C02 level in a well ventilated grow room is about 350-400 ppm. Between 30 to 60 watts per square foot, increase C02 to 1000 ppm and you will maximize yields; that is, only if all the other limiting factors have been properly addressed. Between 60 to 100 watts per square foot, it will require boosting supplementation to 1500-2000 ppm to maximize photosynthesis and yeilds.
If you do not intend to introduce C02 supplementation, then the 600w bulb per square metre light system is more than sufficient. C02 supplementation, though, is essential if you room is closed off, and not equipped with a good ventilation system, for renewing the air and C02 levels. If the C02 level drops below 200 ppm, then photosynthesis virutally stops and your yield will suck huge! Also, with higher C02 levels, your babies can take more heat without getting all stressed out over it, which also obstructs maximum yields.
Rolling Thunder said:um i plan on using co2 but to tell the truth probally not this grow! i will by controllers, co2, more fans and all that after harvest! i dont have much money now that i built the room! c02 sounds confusing though ive never looked into it! so how are these peeps pulling 1-2 lbs per 600???isnt that impossible? isnt it a gram per watt or so???? im a newb im just asking! that would be so nice though! where do i sign up and how do we do this??? for ventalation my plans are to have 2 1000's with one 8 inch eclipse inline and use my 12,000 btu ac if needed i want to try and not use it though, thats why im gonna by this new inline! how shouldi have it all hooked up ventalation wise?
