Is it possible to get lots of weed with no Co2?

[majik77]

i used the yeast/sugar method and i have noticed the buds were alot fuller and looked really healthy had about 1.4oz out of the one plant with using CFL lights from the local hardware store used the 42w CFL had 4 of em hooked up on it.


started with 3 plants but 2 turned hemie so i chopped em down and kept the female ^^

exhaling in the small closet each day for a bit, will supply the room with co2 adequately i think?

Cant be bothered with all the typing, heres a post I chucked on tenacity's GJ a while back:

Howdie Tenacity - Will give you a few pointers;

C02 enrichment is a decent idea, c02 enchances the amount or volume of vield by about 20%, I am not sure exactly where you are in the grow (week wize) however, it really cant hurt. A few concepts you could possibly apply are; c02 candles, Dry ice, LPG, heaters (pending gross area) and finally my favourite, good old soda stream.

C02 candles have their ups and downs, having a live flame in a room can often be dangerous, if you chose to go this way I would suggest buying some smokeless and odorless 99% pure wax paraffin candle and lamp liquid solution.

Dry ice is simply frozen C02, this method is great for small areas. One KG (Killogram) is the equivilant to one KG of C02. You would require one KG or thereabouts per day as one KG will last around 18Hrs and raise the PPM (Parts Per Million) To around 1300PPM. It is generally a good idea to place the dry ice into a polystyrene box or something similar. I would also suggest handling the Dry ice with gloves as its temprature is generally about 42 degress celcius, below zero.


LPG heaters suprisingly also provide a good source of C02, the ignition of LPG (Liguified Petroleum Gas) returns C02. Therefore, if your home climate is cold switch on an LPG heater, warm your home and deliver the C02 to your plants. LPG heating is relatively cost effective as it does not use electricity to function. The primary costs are merely purchacing a heater and paying for LPG refills (which will last many, many hours), I guess the downside would be the increase in heat.

Soda stream is also a good idea, soda stream machines use C02 to carbonate the water. Buy yourself a soda stream machine. Put your Per Hydra (PH) balanced water, plain water not water with nutrient additives into the machine, carbonate the water, put it into a mist sprayer and then spray over the leaves. For this to be effective you need to turn your ventilation down or off for a period. Only practice this method while the lights are running as the plants can not intake the C02 in any other period.

C02 in general is currently rising due to the level of combustion of fossil fuels. The average C02 levels in the air are about 340PPM. For enhanced plant cellular construction the suggested PPM level is 1500PPM or thereabouts. Raising the of C02 about 2000PPM becomes toxic to the plant and 5000PPM toxic to humans. So, with the aim to increase the C02 levels, high enough to truely see a difference in the plant a air tight construction is generally nessacary.

What do you think about soda water? Taking a 2 liter bottle of soda water and opening it in a small grow room.

Personally, a tank and a reg system is the way to go, it all depends what you are trying to achieve at the end of the day though..

I think the major issue of just chucking a bottle of something 'that makes' C02 is you have no proper intsruments to acurately quantify the amount of production, I just don't see the point. In addition to that, alternate methods seem cheap to begin with, over time a key of dry ice a day really adds up.. Not to mention the inconvenience.

If your going to do it, do it right. Air tight, regulated / timed C02 induction, spend the money.. you wont regret it.

But more, on topic, I wouldn't bother dude. In a small time unit for personal amounts you wont really notice the difference, maybe a couple tighter nugs..?
