Co2?

jatoki · 10-03-2003, 01:58 AM

For a number of reasons I cannot install a CO2 tank w/ regulator in my small grow zone. Is the daily release of the gas from an old bb gun's Crossman cylinders useful? Or a waste of money?

A buddy advised me that just my own respiration in the room provided enough added CO2 for the plant. As it's in the back half-bath, I'm in there several times a day.

What's the optimum p/p/m for vigorous growth?

Thanks.

Does no one actually bother to search for anything anymore?

Although mods, I note that CO2 cannot be searched for because it contains less than the 4 character minimum for searching.

requires some more equipment and effort. The use (and amount) of CO2 needs to be strictly controlled, too little and you’re basically wasting time and money, too much and you will poison your precious babies.

The problem most have with CO2 is consistancy of CO2 delivery. To just add a random amount of CO2 periodically will see no substantial (if any) increase in yield. If you are just going to stick a bucket of sugared water and yeast in your grow room then you’re better off just increasing ventilation and airflow so the plant can transpire more efficiently and there are less “air pockets” of “used” air.

Further before thinking about CO2 you have to think about whether your current grow can support it, artificial CO2 supplements will only have a positive effect if used in combination with the right grow temps, additional nutes etc etc.

To add another dimension to the problems there are many different opinions on the level of CO2 that should be in the air in order to create optimum conditions. I’ve heard of rooms running from as little as 500ppm (parts per million) all the way upto 5000ppm.

So, summarising.

When thinking about CO2 you must think about :

1) How much CO2 you want to add to the grow room;
2) How you are going to measure and keep the room at this consitant rate;
3) Whether you can induce the higher temperature needed and the airflow needed;
4) Whether you can schedule your fertilising to a higher level so that the plants can get the
additional nutrients they need to support the extra growth;
5) Do I really need all this hassle.

I don’t personally bother finding that I can get the yield and quality I require using more simple methods (better air circulation, constant harvesting techniques, good mother selection etc etc.).

I do however know some who swear by it and there is absolutely NO DOUBT AT ALL that good use of CO2 will enhance your yield quantity by allowing your plants to work more efficiently, absorb more nutrients and grow faster and larger.

Summer temps have been so hot this year so far though so who knows what will happen next year.

However fo those wanting to try "ghetto" CO2 methods then....roughly a 100g of baking soda and a litre of vinegar produces a cube meter of 1200ppm co2.

Also check out this link here which has some discussion.

Quite sorry. Hadn't seen the search feature since I link directly to this forum. Period. Now I know.

No need to be sorry man.

Just a comment.

As long as we can help!
