Hello everyone, I've been reading around other plant forums and they say that increasing CO2 causes the plants to require less water to grow. If I have high temperatures in my grow is it worth it to make a DIY bottle or two of CO2 to put in there while I'm not around to water them? Anybody have experience with this?
You need to learn to manage temps in your grow room before you mess with CO2. If it's hot in their now it will be even hotter when you seal it up to pump in CO2. What is your set up?
Don't bother with DIY stuff...it won't give you high enough levels. Plants ability to uptake C02 increases with temperature so yes, adding it can help the plabts managing the temps. As mentioned above however, you have to be able to operate the system properly which can be costly. Better read some threads on it and get a handle of what you're getting into.
It's a very small grow, only 6 cu ft of space. I've read mixed reviews on the method. Some people swear by it on other plant forums but some say they don't notice a difference. I don't need to see a difference in growth, all I'm interested in is for my plants to be alive when I get home! Will it harm them if I try it? I may be able to pick up another small fan too.
Focus on proper exhaust first...you aren't going to be able to produce the levels of co2 you'd need to counter an improperly ventilated space.
My set up is a 19x24x32" cabinet with 2 CPU fans at the top for exhaust. I have a passive intake at the bottom with a circulatory fan at plant level. The plants are an indica bagseed at 42 days veg LST'd and topped and fimmed. FFOF soil with FF trio nutes. 164 watts of cfl's I'm switching to flower before I leave tomorrow. I water with pH'd tap water with nutes mixed in typically every 3 days. I let them dry out pretty well before I water them again. Here's what I'm working with. i have a little bit of unexpected extra floor space
LOL no. Co2 is beneficial when all of the plant's processes are increased simultaneously, resulting in faster growth. More heat, light, water, and nutrients are required when running co2 in order for it to be effective. Just raising co2 levels with a bottle of baking soda or whatever doesn't do jack-shit. It's part of a larger process, a symphony if you will, of many processes, not just one.
@[member="Not Sure"] Thanks for your input! I've had great results from a simply DIY diffusor in aquatic plants before, so I figured I'd ask around. I dig the symphonic symbolism!
You know what does help with heat resistance? Silicon No silicon -> heat stress silicon -> no heat stress It's sold under a few brands, I use Rhino skin from advanced nutrients and pro-tekt from dynagro, prefer the rhino skin.
Silica blast from Botanicare has done wonders for me in the past. I had a strain that was very heat sensitive and would foxtail if my temps even reached 80-82 degrees. I noticed much less foxtailing on the same strain when I used silica blast.
