I wouldn't bother with CO2 if you have solid airflow and refreshing. There's no point as if the room is kept around 70-75 plant respiration will be normal. You only really need increased CO2 in LARGE setups that get poor ventilation/airflow and have higher operating temps (The plants respirate more in higher temps so that's where extra CO2 would REALLY be needed.)
20 pounds a month? Pretty much gotta do hydro and gotta do SOG. Figure average of 1 ounce per plant. OK so you have to do a perpetual grow and harvest once a month. 16 ounces per pound times 20 =320 plants harvested each month. Now it takes 3 months total on average to grow 1 plant all the way through to harvest so your gonna need 3 times the amount of plants you harvest...960 plants. might as well make it 1000 plants just for fun. Ok so now your gonna need lights, lots and lots of lights. Lets just figure 50W/plant to get the 1 ounce. Use light movers to get more efficiency and we will say for fun it will double your light capacity. 1000*50=50,000 total watts needed. Lets figure the amperage load shall we? 50,000/240 ( For a big setup like this you really have to use 240 volt ballasts) = 208 amps of power. thats almost 420 amps of 110v power. Thats a big fuggin load for sure, more on the lines of commercial use.
Even here where I live electricity can be as low as 4 cents per KWH at times, even then your bill is going to be in the neighborhood of 2 dollars per hour of lights on. The average rate for electricity is 13 cents per KWH, so then those lights are gonna cost about 6 dollars per hour of lights on....$72/day, BUT the big kicker is that the power companies can charge you more for using more, even here if I power hog I have to pay up to 4x the normal rate, so lets say those lights are now costing about $300 a day to run. BUT since your using light movers you only need half as much power to achieve about the same results, so in a perfect world you would half all your power costs.
Makes you think about the whole thing in a different perspective. Now imagine trimming out 20 pounds of weed by yourself.
thank u...Yeah, I did some math of my own a few days ago, and gave up on trying to educate how it's done.
Sorry, but I'm gonna have to agree with littlegrower, just not with the cynicism, 4 bedrooms, each with 4 1000W lights, total of 16 1000W lights, raging the energy bill, and still not getting 20#s a month, probably 16#s every other month... Make that your goal.
I'll say it again, I don't usually reply to nonsense, but I'm bored, and there are a bunch of overambitious threads just like this one
Learn how to grow first, then worry about getting a bunch of equipment and starting up a warehouse... Jeeze, take it easy, and keep it simple.
And if I don't have anything productive to add, too bad, freedom of speech allows us americans to say what we want, go back to communist china if you want to tell people to shut up if they have nothing to add.
My prediction on the 20# per month=
Epic failure
hahahahhah i would love to see anyone in the world grow 20 lbs a month with only 6 or 7 lights..hahahhahah maybe 6 or 7 in each roomFirst off dont go with sog, if you want to pull weight you gotta grow in soil. You have 4 empty rooms, your going to need 2 of the rooms being clone rooms you need the other two being on oppoisite grow sceduals, your going to need about 6 or 7 lights and a lot of nutrients good luck
im not here to make friends..im here to better myself as a grower and to help ppl when i have a chance..i may not have alot of knowledge to benefit most growers on here but when ppl come on here simply asking us all how to grow almost a unobtainable amount per month then im gona jump in and throw in my cynical 2 cents...but to other ppl and threads that are realistic im not cynical or rude(cept to La9)...Definately 6 in each of the 4 rooms... I grow with 6 lights, check my journal... My average is 6 pounds per harvest...
Just another example of overambition...
Seriously, one pound per 600, one and a half per 1000... Try to get those numbers and you're doing well.
-littlegrower, if you continue being cynical, you aren't going to make friends very fast.
OMEGA GARDEN google it. 4 of those + a ton of mothers and you would be set. Hell you might be able to do it all in 1 roomThanks guy, But i have the money to start up, i have a empy house. I have figured out all the little details such as electricity. My only problem is how to grow it, i guess this is harder then i thought. If nobody has any better ideas i will prob aim for 10 pound a month instead. =) thanks guys
