using dry ice 4 co2

[bigmelho]

Dry Ice def helps your plants grow. Dry Ice is frozen CO2, so when it evaporates it is releasing pure CO2 into the air. If i were you, I would let the CO2 evaporate on its own (loose the warm water). This will slow down the evaporation rate and allow the plants to consume all the CO2. If you have the CO2 release into the air more quickly then there is a greater chance some of it escapes before the plant can absorb it. I have looked into this because I am considering using dry ice as well because CO2 enrichment in the air can increase the growth and quality of plant enormously (as you have seen in your 1in growth).

I am very curious how expensive the dry ice costs you and where you get it from?

Well i got my ice for .99 cents a pound at safeway. co2 is heavier than oxegen, so the co2 stays in the plastic, the more co2 in the plastic the less oxegen ,so this is pushing the oxegen out the top of the plastic.its like putting your plants in a big plastic bag, with the opening on the top and filling the whole thing with co2. dry ice is compressed co2
