Dry Ice as a Carbon Dioxide Source

[MrHowardMarks]

Don't waste your time and money, invest in a tank.

Along the lines of having fun with co2, here's a fun experiment;

Obtain a 2liter plastic bottle, and some dry ice.

Cut a slice of dry ice that is able to fit in the opening of the bottle, long and skinny. Add a little water to the bottle, then drop in the dry ice and quickly close cap, then get the hell away.

Kaboom!

I've also heard it's a curing technique, after the first drying period before sweating, put a little dry ice in a coffee can, and add weed for 2 hours. I imagine it would definately freeze the weed. I've never tried it, just heard about it.

We used to fish off a bridge with CO2 depth charges, it works great too. Take a 2 liter bottle, fill the bottom 1/2 with something heavy like sand, stuff the rest full as possible with dry ice, screw on cap and drill small drip holes into it. toss it over a bridge and wait for the explosion, usually get a few fish to come up also, no loud bang or nothin, just whoosh of water.

 

[MrHowardMarks]

Hahahahhaaaa, that's even cooler, doesn't the drip hole keep pressure from building?

I'd like to try that...

It would be cool to use a larger container, and seperate the water to the bottom.

Along your idea... You could fill it with sand and allow the water to settle to the bottom, then add dry ice on top of the sand, cap it off air tight, and when you chuck it into the water the watered down sand will mix with the ice

Or you could start with a bed of nails on the bottom, then we're talking deadly.

 

[MrHowardMarks]

^for fishing of course

i have a set-up where i am bringing fresh outside air into my growroom using high pwer fans facing upward to my attic from my ceiling, then open window, pulling air into room. is this as good sourse of co2 than any?

 

[MrHowardMarks]

It will keep your co2 regular.

You want to be careful bringing in outside air, pests come with it.

 

[raiderman]

i keep it well screened , but i do have occasional wite flies, thier pretty easy to control seeing i'm a pest control guy . co2 bottles are good but isnt it more for a lareger garden seeing cost and setup or is it worth it?

 

[MrHowardMarks]

If your avatar is your garden, you'll definately see an increase in yield, good looking plants BTW.

A tank setup isn't that expensive, depending on room size.

 

[raiderman]

i may go for it then. and thanks for the compliment , these hash pants are not real wild about nutes,lot of sweat and tears,lol. not to change the subject , i ordered a couple pacs of mr. nice G13 Hashpant sensi seeds,
{hash plants are the only thing i grow by the way}wat do you think of them? are they pretty strong?

 

[MrHowardMarks]

I noticed the MrNice version can handle a little higher nutes in the peak. Taste is similar, a little more earthy.

I love the calyxes on Hash Plant, they are so solid, and defined.

If you like Hash Plant you might want to check out Silver Pearl from SensiSeeds, totally different flavor, but great strain imo. Almost tastes like Sour D without the long flowering time.

 

[raiderman]

sounds great , i will definately get some ,thanks alot.
this bluemoonshine was my last grow , i'm in the middle of flowering another batch rite now . people told me they thought it was opium based ,so intoxicating. yea sensi seeds definately got the gen.
watching your journal, will be watching the days ahead ,looking forward to
getting any hep to do better everytime. read three of Eds books.
but watching your set-up is more on hand learning.i use 600 watt air cooled set up also hortilux bulb,BUT SIX, that sweet. your definately the man.

 

[MrHowardMarks]

Thanks, we definately hijacked this thread.

New avatar! Same garden!

You look like you have skills my friend.

I started out with 2 lights, and added on as I got better. It looks like you know what you're doing, adding more lights doesn't make you a better grower, knowing what the hell you're doing does. It looks like you know what you're doing.

Sensi seeds is by far the best seedbank imo.

 

[raiderman]

yea i'm always changin it. i'm sef employed, i just sit here at the house , grow and hang out with you guys, haha. thanks , sometimes i think i dont no shit wen something comes up though,lol. but a good harvest its worth all the stress.$.

Currently they're getting bottles of yeast with sugar and water thrown in front of their fan and, although it doesn't seem to be a very dramatic reaction, it's releasing a few bubbles here and there so it's economically more sustainable for me.

I just read yesterday that you need a LOT more than people are using. Like for a 10 by 10 room you would need a huge bucket, like 5 or 10 gallons, and it would go through a pound of sugar a week.

Regardless of how much water and sugar it is it just doesn't seem worth it. After doing a lot of research it appears all you get from all that CO2 is maybe 3 or 4 days faster growth over the entire life of the grow. It doesn't make them bigger, they just grow a little faster.

That may be total hogwash but I'm more likely to believe someone that tried it, it worked, and then they quit over someone that just bought all the equipment so subconsciously have a vested interest in it working.

But that doesn't mean I DON'T want to hear that it works well. If you have done a grow with clones and no CO2, then grown under the same conditions using clones from the same mother and used CO2 and you noticed a huge improvement then let's hear it.

 

[MrHowardMarks]

Yeah, I wouldn't know half the shit I know if it wasn't for other people's mistakes, I worked with a group of growers, like a co-op, for the past couple years. They moved on to warehouse growing, and I split.

In the time I was working with them it was like having 5 gardens, with all the extra problems and thoughts of the other growers. When we split up, I stopped contacts, but wished them luck in their endeavors.

I just joined RIU a couple days ago, it's filling the void of not being able to exchange tips and ideas with other growers

Plus there are a lot more people here. I just hope I never come off as cocky, because there are a lot of newbs here asking FAQs all the time.

Overall I'm glad RIU exists, without it I'd have nobody to talk to about the thing I love most in life. Weed. ::

the only thing wrong with dry ice as opposed to the carbon dioxide machines is that dry ice will be inconsistant and the room needs it constantly as soon as you turn down... and then there is the factor of carbon dioxide per square foor which is better accurate with the macine.... you will need to be in the room all the time constantly putting dry ice on water sounds like a bummer if tou use it for full term .... the machine you almost double actual weight because every bud down to the bottom is dank..... as for dry ice i am sure it would work but sounds like alot alot alot more work if you want the results buy the machine they are about 100.00 depending on your room if small you will need only one but if you got 80 lights you will need like 10

huge difference.... did both now use co2 all the time buds are bigger and consistant all the way down to the bottom went from 90lbs to 160lbs every 3 months it works co2 is key but i use the machine run on propane to distribute co2 i have 12 machines each one only does so many plants per square foot

always use an even amount of lights for best results!!! if you have 2 and want to add on add 2 more just my advice lots o luck

 

[MrHowardMarks]

Huh, dug up an old thread hunnie?

Got any pics of this 160 pound garden??? Stats, light #s, plant #s...



I've used co2, and not used it, but I never saw double the yield, 25% at best when running a tank system sustained at 1400 ppm.


But yeah, dry ice = no dice

 

[MrHowardMarks]

You know in order to harvest 160 pounds = 2,560 ounces = 71,680 grams... Excellent growing capabilities and a production strain allowing 1 gram per watt would mean you have 71,680 watts... Which would be 72 x 1000W lights, or 120 x 600W lights...

Needless to say, that's way more than I think anyone could possibly run, so, sorry, I'm going to have to call you out on this one...

*cough*

*bullshit*

*cough*

Oh, and the co2 machines you're speaking of are called generators.

Good luck
