Dry Ice?

[Ser0 Products]

Have any of you guys heard of using dry ice in a cup with water 2 produce C02 for your plant? my homie tells me i shuld do it... anyone?

 

[coach]

yes no need to put in water.Just place above plants and let melt over 6-8 hour of light period

 

[MagusALL]

how much is dry ice(cost) and where do you get it? also how much do you need and how long does it last?

Dry ice i just saw is like $1.60 a LB at any local store IE. Safeway, Vons, Or any place where u live... you ahve 2 be 18 older 2 buy... word... dont u think water would help? or is it just making the ice expell too fast??? cause when u add water it completely fogs up tha billan...

I buy mine at Kroger for about 2 dollars a pound and it comes in blocks of about 2.5 pounds. I bought a styrofoam cooler and poked 6, 1" holes in the bottom of the cooler. Then I set the cooler on top of my light. The heat from the light makes the dry Ice evaporate faster and the CO2 just flows right on top of the plants.

nice... yupp deff hav 2 do sumtin tight like that... thanks man... im surprised this wasnt a previous stated method... i culdnt find it... do you guys hav good success with it or what!?

 

[aeroponics]

if this works then why dont people with Co2 tanks pump out more Co2.. because it seems to me like the dry ice gives off alot of Co2. Can there be to much Co2???

 

[Hiesman]

na there cant be too much co2... for plants its like what oxygen is to humans... cant have too much oxygen right?

 

[Ser0 Products]

yes there can be too much C02... there is a device that shows levels of C02 in the air, or in this case most C02 tanks have a regulator on the out valve... and i dont know the exact amount, but there is a sufficiant amount of c02 to use....

Sparkling water in a spray bottle....spray them on the leafs about 2 hours before lights on and 5 minutes before lights off....always worked for me.

Get small bottles of the water tho cuz once you open the bottle it losses the carbon really fast.

show me proof...

co2 is best at 1500 ppm. i dont have anything to monitor the co2 content but I know 1 pound a day is sufficent to bring my room (900cuft)to 1500 without exaust on, so I put 5 pounds in with the exaust off for 1 hour than back on until it evaporates. i do this every 3 days during flowering. dry ice works but unless you get it from the manufacturer its expensive and kind of a pain. im going with the tank next time.

$1.50 a LB isnt bad...

 

[Doc OG]

I pay 2.00 and the main problem is you basically have to buy it everyday cause theres really no way to stop the evaporation or even slow it down significantly.

Dry can be used in very small grow areas as the amount that is need versus cost would be crazy. Figure you need 1200-1500 ppm to even really get the benfits.Then figure $2 an lb roughly so figure $6 a day from the start of veg all the way through the 12/12 lights on period.So in soil lets say you veg 5-6 weeks thats $2 x 42=$84 minimal actual almost double as the lights will be on 24 hours then you go to flower for oh lets say 9 weeks so 9x30= 270x $2 a day= $540.so your over $600 in dry ice. Now figure a 20 Lb co2 tank costs about $20 to fill and lasts 30 days worth of injections so $35 for veg and then 9 weeks flower so what 2 months so 60 days so $40 plus aweek so $5 so total cost for entire grow is $80 and you can control the amounts and when its released. Or you can use a propane/natural gas setup which uses about 1 tank every month at about $20 but raises the ppm nicely and can add some heat to a cooler room since temps need to be closer to 85 degrees F when using co2. Or another cheap way if you have asmall grow box area is to burn coleman white camping fuel. 2 oz will get you to 1500 ppm in an 8x8 room is an hour and last 12 hours.A gallon costs $6 at walmart.

you do not want more then 1500ppm in the room and there already exist approx. 300ppm already so add 1200ppm, which is why you need a regulator with the tanks, to much will kill all the plant and animal life. dry ice, fermenting alcohol, and simple baking soda and vinegar will all produce CO2 but not enough to worry about and any little bit will certainly benefit the growth process.

wait, so whats a good co2 setup? id like to try this shit out and got like $120 to spend. nothing with a flame though. im not always there to act like chuck and larry.

 

[Ser0 Products]

look into Co2 Tanks... rental or for own... i dont know prices... just google, couldnt be that hard... i dk where u would get it refilled or anything... but they out there... im just goin with tha quick n easy method of dry ice... ima have 2 take flicks 2, my plant is gonna look like a monster arising from tha fog!!!

 

[FilthyFletch]

if you have a $120 and your grow area isnt too big maybe 6x6 or less.Id reccomend a simple co2 boost buckets.Its no flame no co2 tanks all in one setup.Just plug it in and away you go.when its empty you order a new bucket filled with the co2 making organisms.Check ebay for best prieces or google co2 boost bucket and look around

Wow, havnt heard of that one yet. Does it beat one of the Co2 tanks or what ever?
