spraying club soda on leaves?

i saw a you tube thing that had some guy on who said ''spraying your leaves will be like the plant main lining co2'', but the temps have to be below 80*, anyone try this?

I tried it. Thought I would folar feed with club soda and my flowering nute... used it on some female Cali-O's... I fucked up and used too strong of a dilution. Within minutes the plants wilted and were leaning over, leaves pointed down. It didn't quite kill them, but the crazy thing was that the shock reversed the sex of 3 from female to male.

even if it would work, I doubt the quantity of co2 in a bottle is worth the money you pay for it. :2cents:
 
i did this for quite some time. i felt at the time that i helped with the hardiness of my strains. i began developing nine finger leaves on a regular basis. i no longer use this method, but felt i had good results at the time.

just thot i'd chime in.

well I don't have a garage and live in a busy neighborhood so using actual co2 is too conspicuous for me sadly.


Homemade Co2 Generator Materials Two-liter bottle “coca cola type bottle.”
One Spare bottle top “you’ll see why.”
One funnel “so things don’t get to messy.”
Aquarium Air feed line.
Silicon sealant “the stuff that’s used in kitchens and bathrooms.”
Drill Bit and a drill “drill bit should be a little smaller than your tubing.”
. Step One
top-homemade-co2-genarator.jpg

What you want to make is a hole in your two liter bottle top with that drill bit “ just a little smaller than the air-line you’ve bought” but if that sounds like to much trouble then just push a pair of sharp scissors, “just don’t come crying to me when you’ve impaled your-self on those scissors.”


outlet-homemade-co2-generator.jpg

. Step Two
Now pull the air-line-tubing through the hole in the cap “about an inch will do, just as long as its above the water line.” Then seal in place with your silicon sealant, you’ll need to leave the cap to dry over night before using it.
P.s try an not get any silicon sealant on the thread of your bottle cap, as it a real sod to remove.

. Step Three “only for using with a fish tank.”
Cut your air-line about four inches away from the bottle top and plumb in that one way valve “ make very sure the arrow that’s on the one-way-valve is pointing away from the bottle top, otherwise you’ll be building yeast time bomb.”

. Step Four
Ok this is the fun part I forgot to take any picture, but its easy enough, all your doing is mixing some ingredients up “just like a recipe.”
First fill up your Co2 bottle to half way with warm water, but not to hot as you’ll kill the yeast “one litre.”
Now add two cups of sugar.
With that spare bottle top, fit on top and shake until most of that sugar is dissolved “ this may take a while.”
After that sugar is dissolved, fill the rest of the bottle up with cold water.
Pop in a tablespoon of baker yeast and also the pinch of baking soda also, and give another shake.
Take the spare top off and screw on your now dry bottle top with the tubing sticking out, and make sure the water level is still below the tubing.

. Step Five

Now place the tubing from which your Co2 will come from into your mini grow room and wait, yes wait, the yeast may take up three days before the yeast starts to react with the sugar.

. How Long Will My Co2 generator Last ?.

Well the more yeast you add the faster your Co2 generator will produce, but will also deplete faster.
The more Sugar you add the longer your Co2 generator will produce Co2 for,but will produce Co2 slower.
For bigger grows you can duplicate the process using a 5 gallon water jug.

Hey!

Did you know that Dry Ice is CO2?

Costs about $0.60 a pound around here, so a pound a day will create about a pound of co2 and it'll do it over a 12hr period during lights on...
A pound of co2 per day is about what is required for a 24hr period for a room about 8'X8'X'8. CO2 is no benefit during lights off, however co2 has very little (if any) benefit after about the 3rd week of flower. So a pound of dry ice every 24hrs only adds $30 to the cost of your grow if you veg for 30 days and stop after 3 weeks in flower.

thank you for all your posts, i am glad i didnt mess around with the club soda, as my poor Jilly Bean tree is already looking very unhappy, i have 2 20lbs. bottles but cant afford the regulator or speed control just yet, so i have been trying my old sugar/yeast method,, (thank you stress test),and have it on a timer, of 15 mins on, 15 off for the duration of 18 hrs, (while my lights are on), i built a new room that is 4 deep, 8 wide and 8 tall, which is alot bigger than my old box of 3 deep, 3 wide, and 5 tall, i usually go with the HPS when my plants are teenagers, but decided to stay with the 2 T-8's and 2 cfl's for a few more weeks, i cant seem to get the environment just right yet., but that will be a whole different post., i will take some pics today, hopefully someone can help me out, and the dry ice is good, expecially when its a little warmer in the room, because it will help drop the temp a little, and my plants always seemed to perk up a bit when i would throw a block in there with them, but a 10lbs block would be gone in two days, and its about a dollar a pound so i only do it when the temps are up. the guy that said to spray the club soda on em had some beautiful healthy trees, he showed on the vid, so i thought i would scout it out., but it seems kinda iffy.

A room that size (4X8X8) should only need about 1/2 pound of dry ice per day in veg, and 1/4 once flipped 12/12. Think about it, that is 1/2 pound of pure CO2 in 256 cubic feet.

ya i gotcha, but the place i get my dry ice only sells it in 10 lbs blocks, i guess i will have to break it, and put the other half in a cooler, just seems to be a waste, cause even in a cooler it will melt

you can brew beer and run an airline from the airlock. the airlock will bubble letting you know co2 is being produced. run line to back of circulation fan. you can also drip vinegar into baking soda for co2 . but it stinks like vinegar. i tried every method of co2 years ago . then i quit and bought both tank regulator ect and a propane one for winter.

thanks superman, i did the sugar yeast thing for right now, but i am buying a reg. for my 20 lbs tank on wednesday, i want to do this right but im on a budget., so one thing at a time, i got busy so i wasnt able to get pics just yet,so i can show what i have going, but will try today.

I realized it'd be too much of a hassle to store dry ice and use small amounts...I heard it's kind of pointless to supply random uneven amounts of co2, since you very well could cause more harm that could.
 
ive always wanted to try this but could never find any soda without salts in it. thats where the idea falls short i think. most people dont look on the bottle and see that there is like 15-35% sodium in club soda. that will kill plants really fast esp under HIDS. there is another way to produce CO2 for small grows. still trying to figure out how to regulate the reaction, but basicly adding H2O2 to active carbon will produce CO2 gas. im still playing with it so i know it has minimal affect to the plants, but potential is there. thought i'd share a lil better living through chemistry

Someone that reads labels AND thinks...I like you already.

Carbon dioxide and water form carbonic acid(H2CO3) which has a PH of 3-4,they use to add quinine. The sodium you noticed on the label probably is sodium bicarbonate.

You can easily make your own soda water. There are seltzer syphon/seltzer bottles at most kitchen stores.

If your the DIY type www.etsy.com/blog/en/2011/how-tuesday-build-your-own-seltzer-maker/

I did some research on this soda water CO2 thing awhile back.

Pine

I did some quick research.

Lets start with some facts
- The amount of C02 in the air is about 0.04% (0.0004 as a fraction)
- The amount of C02 recommended for C02 supplementation of MJ is 0.12% to 0.15%.
- C02 supplementation is more effective with more light.
- A 2'x4'x4' box contains contains 32 cubic feet of air - or about 906 liters
- thus a 2'x4'x4' box (the size of combined veg and flower in your cab) contains about 0.36 liters (0.04%*906) of C02
- According to this guy (http://www.science-house.org/CO2/activities/co2/soda.html), a 16oz bottle of soda contains one liter of C02
- Thus if you could get all of the CO2 out of the soda bottle to displace air in the box you could get the amount of C02 in the box up to 1.36 liters (the original 0.36 plus 1).
- This would leave the concentration of CO2 in the box at 0.15% which is right about the recommended level.

Sounds good right?

Well it is not so good considering that the 2'x4'x4' box is going to need to be exhausted frequently - or continuously in absence of a timer or controller. Even if you could let it rock for 30 minutes before exhausting on a timer, you would have to put in a soda bottle worth of C02 in the box every 30 minutes to achieve the recommended level of supplementation. Also you probably can't get the liter of C02 contained in a 16oz bottle of soda water into the box by misting; some is going to escape & 16oz is hell of a lot of misting for a few plants.

What this suggest to me is that spraying soda water on plants is not an effective way to supplement CO2.

Dont do this. You can't apply CO2 in this manner. It will just end up slowing the plants down.

CO2 levels need to be as constant as possible.


The only reasonable approach to CO2 enrichment is with a constant source (tank or generator) with accurate controllable flow rate coupled with an active monitoring device.

Trying yeast, club soda, CO2 pellets, or even a tank on a timer will result in confusing your plants and slowing them down in some cases significantly.

ok, well i got a regulator, and 2, 20 lbs tanks, i just dont know how to hook this regulator up to a timer, i tried the yeast / sugar thing for the last two weeks and saw very little progress, and im affraid to try the club soda foli feed, i did get some pics of what is going on, i have all but given up on this jilly bean tree, even though it kills me to do so, i just have no idea what to do to save her, maybe someone can help.
