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

[BiggFunkNugg]

I have never been able to find a source for Co2 and feel like my crops suffer heavily because I am lacking it.

I know u can grow bud without Co2, but is there anybody out there who gets seriously nice and profitably crops without ever using Co2?

Without using Co2, what was the highest gram to watt ratio u ever got?

[chemicalcomfort]

Well I actually haven't started my grow yet but I have lots of plans in the making. It definitely seemed like I was gonna have some Co2 problems in my room since it's gonna be sealed, so what I did was go the DWC (deep water culture) route where you use a "bubblestone" that creates a lot of oxygen in the water and the plants get it through the roots. Then on top of that I'll use a sprayer filled with carbonated water to consistently spray the plants and the room to help insure they get adequate air (even though the bubblestone is pretty much guaranteed to be enough as that's what DWC systems are known for).

edit: fixed the co2/oxygen misnomar, thx doober

no matter what the plants need Co2 to live. at it's simplest, water+light+co2 == buds

[BiggFunkNugg]

i UNDERSTAND THAT. THEY GET cO2 FROM THE FRESH AIR THAT IS BROUGHT IN. I AM TALKING ABOUT EXTRA CO2. oBVIOUSLY i AM NOT GOING OUT OF MY WAY TO DEPRIVE THEM OF THE CO2 THEY ALREADY HAVE.

As long as you don't have like 30 plants in flowering in a small area, no supplemental CO2 is alright. Smaller grows don't need CO2 and they still have excellent yield if maintained properly...

I don't think the problem is lack of CO2 but I couldn't guess what's causing the low yields from the information you've given us so far.

Take a look at some of these vids, they contain heaps of great tips: http://www.greenhouseseeds.nl/shop/i...e_id=ghgrowdvd


GL man!!

If you want extra CO2 try the yeast/sugar method.

[linedrivr]

plenty of fresh air circulating thru your grow 24/7 with the standard 350 average of C02 thats always in the air we breathe will suffice for growing excellent amounts of bud. If your yields are low, your problem lies elsewhere.

Low yield can result from the following:

high temperature
low temperature
low CO2
high humidity
low humidity
poor nutrients
strian problems
poor lighting
too much watering
too little watering
high ph
too low ph
damaged lighting schedule
mold/pests

not to mention countless others. don't jump to conclusions before you check everything that you can. It is possible to get 2 lbs per 1000w light without using artificial co2. More ventilation is always better. Drop 150 on a good inline fan, it is worth it.

Thanks for the tips guys. I'm no longer discouraged by not having any.

[hexter19]

I wouldnt be discouraged at all. Alot of the technics and methods discussed on the forums is all about bonus stuff. MJ is a weed and a prolific one at that. You can get very good grows with out all the bells and whistles. Will the extras (like a CO2 emitter enhance the grow? Yes. Is it an end all be all of the grow? No. Getting the bacics down and learning the plant is the best thing you can do at 1st. Then as you understand the subtlties of the plant and its growth cycle then consider adding the little extras to take a good drow into a great one. Just my .02. Good Luck Bro!

thats just making it seem as if he HAS to have a very expensive setup to get a decent yield,

plants need light water air a growing medium and nutrients, if your air exchange is good c02 is by no means a must have but wil boost your yield if used properly, if used improperly, it will just cost a load od cash for hardly anything, cannabis plants can use up to 5 times the amount of c02 that naturally occurs in the air,
but without growing in a sealed room isnt c02 useless?

i hope i did not sound rude, i know nothing about c02 enrichment except for what i have read, but am looking into installing dampers in my exhaust to seal it off to keep the c02 in, i may mess with it if the pvc hydro hut dosent kill my plants with a 1000 watt system next run,

c02 to the roots equals death.

the air stone your using to bubble your DWC system is pumping oxygen to the roots, direct c02 to the roots is seriously bad
