Looks good ^^

Might be a little risky if it touches the hot bulbs no?

Dry ice gets very expensive with prolonged use. Two pounds of dry ice will raise the CO level in a 10 x 10-foot {3 m²) grow room to about 2000 ppm for a 24-hour period. One chagrined grower remarked, "I can't believe that stuff melts so fast:'

Growers have long used large, insulated tanks filled with dry ice to add C02• Dry ice is carbon dioxide that has been chilled and compressed.

As it melts, it changes from solid to gas. Gaseous col can be mixed into the air with fans that circulate it among the plants. Dry ice works well on a smaller scale without a tank and converter. It is readily available (check out the Yellow Pages) and inexpensive. Because C02 has no liquid stage, the transformation from solid to gas as the ice melts is clean and tidy. It's also easy to approximate the amount of CO, being released.

A pound of dry ice is equal to a pound of liquid C02. Determining the thawing period for a particular size of dry ice will allow you to estimate how much C02 is released during a particular time period. To prolong the thawing process, put dry ice in insulating containers such as foam ice coolers, and cut holes in the top and sides to release the C02. The size and number of holes allow you to control the rate at which the block melts and releases col.

Dry ice is economical and risk free; it releases no toxic gases, heat, or water. Although dry ice is easier to handle than compressed CO2 tanks, it is difficult to store. The melting can be lowed through insulation, but it cannot be stopped.

Because it is extremely cold, dry ice can also cause tissue damage or burn the skin after prolonged contact.

The droplets evaporate before holding the lamp, and CO2 to be heavier than oxygen drops very fast

PEACE!!

nice man thanks

Very interesting , never thought of doing it this way. Shot

I buy dry ice paid 5 real

I think it will take 2 Euro per kilo

I buy in a ice cream factory

I also suitable for hot regions, even though I use on the part of the morning from 4 to 6 hours of the morning,

hours that the stomachs of plants are open in the summer is good, I can make between 25 and 27 degrees celsius

hi,

I do not know,very interesting Peace

i heard when using dry ice you should turn all lights off so the h20 don't burn down, but i think this idea works if you don't have a air tank and regulator, i have heard water,sugar and yeast work good too for generating raw h20

Just leave the ventilation on, the exhauster will do the job.

Yes yeast with sugar works great.

Peace!

Yeast and sugar is the way i make mine as well..

We have a dry ice manufacturing compony quite close to where i work. Their prices is cheap enough to play with DECENTLY twice a month. Sometimes i overdo things but hey, my plants still thrive after all these years of "playing" with them
