Perpetual C02 Question

Hello All!

I have a perpertual garden and I am thinking about adding C02 to the mix. Now I know your supposed to increase the PPM as the plants get older. I run 2 flowering sessions about 5 weeks apart. Will it affect the younger plants if my room is at 1500 ppm?

Thanks!

Explain why you should have to increase co2 levels for older plants. Seriously, there is no way that co2 levels 1500ppm or less will be damaging to any stage.

I dont know the science of it, I am new to Co2 so im learning what I can as I go. But if plants that are flowering for 1 week can handle 1500 ppm then I have nothing to worry about.
 
I have no experience with CO2 levels this high, but they definately could be unhealthy for younger plants. Plants will not use PPMs that high until they are older and have a higher PPM of nutrients and may need the higher level of oxygen in the air, although i am not sure. You want to start with lower levels of CO2 that your plants will use and work your way up along with your nutrients. I would suggest trying to block off the two areas, or your plants could be fine. Good luck.

Hey Greenmonster, thats what I have heard is that it should match your ppms. I just want to be able to maximize the potential of my Co2 system without hurting my younger plants. Anyone who runs Co2 want to chime in?

Thanks!

the hole increaseing levels of c02 is about saving money any palnt can use 1200ppm and will not be damage until over like 5000ppm so dont worry youl be fine thats the sience. plain and simple

i have clone seedling 8 week vegiing plants all at 1200ppm in my room somtimes at the moment everything is flowering and funny thing is money is tight so ppm is set to 800 go figure as the world turns.

It is not unhealthy for young plants. The co2 is the plant's source of carbon for making sugars and hormones and they release oxygen as a waste product. There is no equivalent to nute burn that I'm aware of when supplementing co2. You have to remember that the Earth used to have levels higher than 2000ppm millions of years ago and plants thrived.

I have been running co2 for years and have plants in the flower room that range in age and I run at 1800ppm no issues. I run at 1800 so as to have the whole room at 1500.

Plants use co2 up fast when they can get it, plants will deplete co2 in less than 2 minuets around the plant if the air is stagnant.

The most important thing to know about using co2 is the air has to be clean of co2 and o2 should be introduced about an hour before the lights go out. Your plants require o2 when the lights are off.
 
The only thing that changes in regard to plant longevity and PPm intake is that after 40-45 days or so,the plants will not utilize the excess co2.If you have younger plants in there it certainly wont harm them just as high enrichment levels (below 5000PPM of course) will not harm a seedling or new clone.they simply wont utilize it all and much will be wasted.Better to have it and waste some than not to have it when it could be utilized

Not the most important because it is not necessary. There's plenty of o2 in the air at lights out, they've made most of it.

I run CO2 full time for veg/flower for the whole summer. Clones, seedlings, cuttings, clones.. They all grow better with CO2.. So much better in fact I might go ahead and turn it all back on, winter or not.
 
I only flower with co2.I used to use expensive horticultural lamps for veg too..live and learn I guess.Vegging a plant to its potential doesnt take much extra effort like flowering does IMO.
