Question regarding CO2

I am going to be using the $4 CO2 bottle system to increase the CO2 in the grow room. Running out the top of each bottle I will have a line of plastic aquarium tubing to ensure no 'bubbles' can leak. My question is how best to direct the CO2 to the plants.

I could ..

1. Run the CO2 directly behind a fan directed at the plants? As CO2 is heavier than air the fan should suck in the CO2 and throw it to the leaves.

2. Run the aquarium tubing directly into the neoprene collars? Will the plants benefit more from CO2 at the roots?

Any further idea's or advice?

Hey stinkbud I was wondering if once your dvd comes out if this thread will be removed or deleted? I sure hope not cause I refer back to it like as it was a grow bible. I plan on buying it anyway but I still want to be able to come back here for help and advise. peace

This thread will always keep going unless they lock it.

DVD is on hold for security reasons. I'm working on finding a distributor but I can't figure out a way to keep from being traced because of the taxes I will have to pay.

I'm OK in my State but I worry about distributing to other less friendly States.

It is quite satisfying getting to this point. Mini six-hole system with 10 gallon res. Day 11 of flower. 1st timer. yep. Lots of Stink research and investment. Thanks.

I wonder if I am getting yellow, rusty spots because I am running Bloom formula since day 1 of flower and I am Nitrogen deficient??? Happening on lower, larger fan leaves on mature plants. Rusty, yellow spots. However, tips aren't rusty or yellow. Larger fan leaves are a little dry. New growth looks good. Also had osc. fan running on those plants 24/7. Since problem a couple days ago I have moved desk fans underneath NFT blowing upwards during lights on only, including tubing for CO2. Osc. fan blows away from plants now. Worried also that I was drying and wind burning them from too much wind.

5 Blueberrys
CO2 at 1500
temp is 83.5 day and 69 night
Res at 68 degrees
PPM has been constant at 1900-2000 ppm since day 7 of veg.
600 W HPS
PH steady at 5.8
Humidity set at 60% with dehumidifier

Any help or advise. Thanks.

It could be normal. Remember, a whole bunch of bottom leaves are going to die no matter what. They get old and turn yellow. I just go in and pick off all the yellow leaves once a week.

if not...

I would always start with changing my res first.

Those fans might be drying out the bottom leaves.

The light looks a little too close. If you notice the leaves curling up that tells you you have a heat problem.

Your room temp is ok so it must be the light distance.

Good luck bro!

Hey Stinkbud or some other buddies, I finally got my new strains into the veg system. The thing is that I am having a problem on 3 of the plants that are growing and I need some help on what you guys think the problem is. I have narrowed it down to nute burn or heat burn, but Im thinkin more like nute burn. I germed in paper towl then into rapid rooter like you said. Then I carefully ripped them apart and put them straight into veg system under 980ppm on the nutes. PH at 5.8 and a total of eight 26watt CFL's 6500k Daylight spectrum.
I used your veg formula of course and the temps been around 77F and 30%humidity.

I have DP - Blueberry,
GH - White Widow, GH - Big Bang,
GH - The Church

Big Bang and The Church are the two strains that have had this happen to, besides that the White Widow and Blueberry have been growin wonderfully!
Thanks for the help in advance!

I'm just guessing but it looks like nute burn to me. Maybe those strains can't handle much at the start.

Try going down to 300-500 ppm and see if that helps. Watch the new growth carefully.

have you heard of the powder fert stuff? before it comes to liquid, gives u really LOW ppm a buddy told me, what u think of that

2) what you think of vertical growing stink?

What do the roots look like? I wonder if they aren't a bit young still for anything but water? Perhaps a 200PPM solution if anything?

For sum Reason my clone unit isnt working right. My Cuttings keep getting really moist all the way through the stem to the top nd make the cuttings relly soggy n die. i dno wats wrong? I had 3 GDP at least 3" cuttings nd that happend to all of them. Im on the step where im suposed to transfer my veg unit to the first flower unit but i have no clones yet for the next VEG. I think im gna have to buy sum for the next round of Vegging then take cuttings off the First flowerin plants nd put them in the cloner .

hey salad
i had the same prob its damping off
your neoprene disks arent tight enough around the plant
i changed disks and pulled the little bitchs futher down the disks
hope this helps
ps
i had one fall over it was 6" tall i cut the bottom off and put it back in the cloner and it poped roots again

yellowing leaves dry and brittle. 5 weeks in flower.

The room environment has been good..under 60% RH
65 deg at night 85deg day...

co2 starvation? my first few harvests were lush and green without co2, but i did have the vent fan on 24/7 before i added the co2. now it just comes on 4 times a day before co2 injection.

fungus?
maybe a deficiency?
or salt buildup?

Im due for a res change....will this help? should i flush before adding nutes?

perhaps a potassium deficiencie, how many weeks till your final flush? your in 5 weeks flowering, i think an additive of bloom boosters will help you out, since phosphorous and potash are critical at this precise point of flowering, right here at this stage will affect your yield considerably if its a P or K def...if your going organic you may want to try one of fox farms bloom products, cha ching or beastie bloomes, if chemical you may want to try liquid kool bloom, the fox farms are off the charts high in P, but the kool bloom is a 0-10-10

I don't think its the nutes. Everything was fine before you added CO2. You never had any problems before with your nutes and you where doing the same thing.

What has changed since you added the CO2? What if you where actually running your CO2 below 500PPM? With the extra heat that would explain everything.

I would think about ditching the CO2 until you can afford a controller.

There are two different types of collars.

One type is made of neoprene and is about 1/2" thick. They have a tendency to let water wick up the stem and cause damping off disease.

The other type is made from high density foam and is twice as thick. They are also quite a bit more firm than the neoprene collars. They completely seal the stem from water.

Stay away from the thin neoprene collars and look for the thick foam ones.

If you do end up with damping off disease, scrape off the rotten parts with a knife.

Then put a thin coat of baking soda around the wound to keep it dry. It will take about a week to fully heal.

If it's totally rotten then you should just clip the plant off above the wound and put it back into the cloner to root again.

I've saved a couple of plants this way.

Good luck bro!

Im so glad you know my history Stink. Its gotta be the c02, ever since i added it, things got out of whack.

Until i get my controller im going back to what has worked in the past. Ive been searching around,,do you have a link to the type of controller you use?

thanks again man!
