CO2??? Flowering Now/ Temp Problem

I have 47 PK plants growing is Sunshine Mix # 4 with 1/2 bag Peat Moss and 2 bags Perlite added. I use Safers Fish elusion and Mari cal Grow 20-20-20 . Lighting is 2 1000 lights. Plants are now 5 weeks old and are doing real well. I am putting them into 12/12 today. Is it to late to use CO2.
I have taken 170 clones and the clones are doing OK.?????
Should I introduce CO2 now, or forget it and wait until I plant the clones and start new grow.??? If I was to use CO2 I would use Coleman Camp Light with Kerosene ( its what I have on hand) How long would I keep liter CO2 in room that is air tight and 7 feet by 14 feet by 9 feet. Is there a formula somewhere I can use.
My clones are taking a real long time to grow roots. The temperature up here has dropped quite a bit and this am the temp in the cloning:hippy:/mother room was only 52 degrees. This is the first time I thought about measuring room temp in that room and was aghast it was so cool. Is this the problem??? I have 4 Mothers in that room and they are doing fantastic with 2, 42 inch Florissant bulbs. Thanks in advance and Pay It Forward

I've known a few people who use Co2 ONLY during flower. I'm way too new to give you advice on how much via your planned method however.:D

My long term goal is a generator with a PPM monitoring system. In that case you'd go somewhere close to 1000ppm. I can only hope for you, in that someone knows how much a kerosene lamp can generate. Once you know that you could figure it out easily enough using the timer method I'd think.

You may also look into the enzymatic CO2. It's available on e-bay. You mix water and glucose, then add a packet of enzymes that generate CO2 as they eat the sugars. In a plastic 2 liter bottle, you can run a hose off the cap to release the CO2 directly over the plants. When it stops working, you add table sugar to new water and put some of the old fluid into the new sugar water and the process starts over.

As for the Temps. That is a bit cold. I'd say get those temps up to at least the high 60s. This isn't too likely to kill them(grown plants), but it will stress them and could reduce yield once you start flowering. It would also slow new growth in fresh cuttings for sure. I seem to remember cloning temps should be close to 80 deg F.

Good luck!

This is just basic fermentation. Same thing for getting a mash together for making moonshine.
1. Go to the brew shop and get (2) 7 gallon buckets and an air lock.
2. Dump 5lbs of sugar and 5 gallons of water in each bucket.
3. Put in a package of brewers yeast into each bucket.
4. Put the lids on each bucket with the air locks and you have a CO2 supply for a few weeks. As long as the air lock is percolating, you are producing CO2.

I run "The Bucket".... It has an organic compound that brakes down and emits CO2 in a bucket through a pump and over the plants every 15 min alternating with my fans ONLY durning light hours... This system will run for 6 to 8 months (depending on useage) before a refill.... I don't waste any CO2 on vegging....PPM is around 1200 unless I have to deal with spidermights then I'll shut the fans down and crank it up to 20,000ppm for 1 hour and that will choke all the mites rite out!

Wow, I'm guessing that would choke out ANY pest! :microwave: (Make sure your cat left the room too!!:D)

You know it!!! Beats the hell out of nukeing the plants every 3 days with neem oil....:thumbsup:

:pimp:
Thanks for the answers and am going to try the Lamp and Kerosene.
I am going to weigh it when it is empty, fill er up and light it and check in 1 hour to see how high the CO2 reading in the room is and go from there.

The Yeast gig, does it really work well, have read many different views. Have you personally used it or just got told it works. LOL LOL ??????

What is highest CO2 reading that works best 1500 to 2000 PPM?????

I am a legal Designated Grower through Health Canada, I have contracts with 4 clients for a total plant count of 156 soon to be in full production. What is the best way to set up a 3 or 4 stage operation, when should Clones be added or planted into soil or pipes????

Will supply pictures today of Grow Rooms and such. Again thanks for the input and will have tons more questions down the road.

Plants stop growing all together at 200ppm and lower. They slow a lot at anything over 1300ppm. So, most people aim for somewhere around 1100-1200ppm. However with no automatic sensors MANY people just do timed release of small doses of CO2. Ambient CO2 world wide is anywhere from 250ppm-350ppm. PLUS CO2 weighs more then regular air. thus FANS are needed to keep it up off the floor.

In a sealed room the yeast thing will fill up the room. YES it does work.

156 plants?? WOW. Little bigger then I assumed.:jointsmile: I'm in Colorado, US. With my 4 care takers, I can have a total of 24 plants!:wtf:

For that much space you'll need a lot of fans and a lot of kerosene lamps!:D
I'd suggest a natural gas CO2 generator. You can have it connected directly to your house/buisness's heating gas line and generate CO2 in MUCH larger areas. plus you don't have to haul fuel.

For an operation that large, you want to go with a CO2 generator that you can hook up to your homes gas system. A lamp won't cut it, CO2 tanks will but you'll need a few of them.

I am only going to gas the 43 I have in flower right now as a test and work out the kinks as I go along. When I get the donations from the growing I will be able to afford a CO2 generator. My problem is we are out on a farm and do not use natural gas we use coal oil or heating fuel. I use diesel as it is cheaper, and my main grow room is 20 x 16 x 8 and the other room is 16 x 12 x 8 all wired with 220 and ready to go ahead, once the Govt changes the Law again in our favour I hope.
Anyway thank you for the help and will keep you posted.

Pay It Forward

You can also get that CO2 generator to run on Propane. I don't think there is even a change in price.

Then you could either have small or large tanks of propane or even a HUGE tank filled by a truck. Either way (Propane/Natural gas), the generators are the way to go!:thumbsup:

Good luck :hippy:

I would be careful so that you dont choke yourself out. co2 is an odorless gas that can get you before you even know it.
