co2 generator?

[john appleseed]

i read on here or overgrow how to make a co2 gen. with yeast, water, and someouther suff i don't remember. any of ya'll heard of this? i can 't find that info again and i need to start enriching for my girls.

What type of light are you using? Fluorescent light does not produce enough lumens for the plant to use the extra CO². You must have HID lights 400w or better for the CO² to be any real help.

i have (2) 400w mh and (6) 40wfloro vertical.a fan on them. and an ac vent above blowing down on everything(set at 73f)have had a problem with Mn toxicity due to tape water.epsom saltwater fix. use rain water now.everything is doing ok now. figured start co2 for 4 wks then flower.let me know what ya think.oh yeah my girls are pretty old (3 mos) not real tall but healthy for plants under floro only for 2 months but now we are cooking with Mh baby.

I run CO² every day veg and flower. As long as you have the HID lights you are fine. What are you going to use to flower?

[john appleseed]

im gonna use (1) 400w mh and (4)70whps.its all i have man.the outher mh will be on the veg side of the grow room.anyway what is this about mixing yeast sugar and what not in a 5 gal bucket with a lid and spout?I read it on the net somewhere and of course i'm a pothead so i forget a few things.

FORGET IT. Its not efficient to control or maintain high levels and smells stonger than your buds will. But if you insist on this method, a pound of sugar added to warm water (fill 1/2 of your 5 gallon bucket) and 2 packets of baking yeast. The yeast eats the sugar and Co2 is the biproduct. last a couple of days and smells like stale beer 10-fold. Another science fair method is a vinegar drip over baking soda and less smelly. If your serious about healthy plants get a tank system.

zandor dont plants benifit more from co2 at night ?thats what i always thought i heard,
if so im wondering why it would matter what lights you use with co2 if the lights are off

thanks

If I was to get a CO2 tank (not hard at all) what would I attach to it to have it release CO2 at regular intervals? This is the only thing stopping me from doing this. Thanks in advance.

No the plant can only process the extra amount of CO² when the lights are on. CO² in the dark is only a waist of money, unless you are using it as a pest control but that would be expensive pest control.

It takes about 10,000 lumens for the plant to process CO² levels above 900 ppm. Normal air runs about 300 ppm and for a good growth supplement the level is above 1500 ppm. I run mine at 1800 ppm just so you can compair.

You need a regulator with a solenoid switch to turn off and on the flow.

This set up is 76.99

You could use a timmer but that is not the best thing. For the best results where you dont waist the gas is to use a monitor/controler

That one is 350.00 bucks. This is not cheep stuff but it is some of the best. The one I use is the C.A.P. XGC-1 Xtreme Greenhouse Controller it regulates the whole environment...but they cost about a grand each.
