bought these at my local hydro shop he said i could put them into the water and my plants would exorbe the c02 through the roots! now im unsure weather this is fact based or just a line he spun to get the sale but i did think i could use them for misting?
what do u think?:blsmoke:

they disolve in water like aspirn FIZZzzz....

Well the fact that plants take in CO2 through the leaves and not the roots *in theory* makes these a waste of money - another marketing thievery.

when i say misting i mean for the leaves not fogging or aero/hydro i know the roots need oxgen and will suffercate but i read in a thread that carbonatied water is good to spray on the leaves so i thought that these may work in the sameway only with more C02

Do the powder co2 water enrichment 4 aquariums work when u dissolve it into da hydro solution? i'm usin it n givin it random doses. don't know if its makin a difference though.

I'd say they're essentially Alkaseltzer

If you have em then yeah, foliar feed with water that's still bubbling with it. Not gonna make a huge difference but not gonna hurt.

Co2 Tablets

These tablets are designed as a cheap alternative to other carbon dioxide systems. By offering gas directly to the root of the plant there is a significant increase in growth. Use one tablet for every 200 ltrs of water, in soil or hydroponics. Carbon dioxide is active for 4-6 hours in the water after dosing. The addition of the dosing machine, which fits onto any tank, regulates the entire process for you. BUYCo2 Tabs x 50 £9.00 BUYAutomatic Co2 Doser £90.00

Thats crap... Chlorophyll absorbs the rays of sunlight, and uses them in combination with water and carbon dioxide to generate glucose, the substance that fuels the growth of a plant... you cant just shoot Co2 into the water and expect to have the same results. Besides, during the night time plants actually reverse this process. It is at night time when they use the glucose they made during the day by photosynthesis. Oxygen now acts as the triggering mechanism... which means at night time they release Co2 back into the air. This is why ventilation is impotant to indoor gardens.

I'm sure oxygen is not used at all, and is given off as a waste product? Water + CO2 = glucose + oxygen

The glucose is either used immediately for respiration/growth or stored as starch in the roots (which is insoluble.) Oxygen is just given off.

Nevertheless, I agree with you on the fact that roots cannot take in CO2; think plants, trees out door, their roots are under the ground, in soil, most of the time which cannot let gas pass through.

Plants do have a net release of carbon dioxide at night due to cellular
respiration. Both animals and plants undergo cellular respiration constantly.
However, in the light, plants produce much more oxygen via photosynthesis than
they consume in cellular respiration. However it's not enough to kill you.. they still release small amounts of carbon dioxide at night though.

I'm basically going to school for botany. Look up this one book called "Beginning Hydroponics" its by Richard E. Nicholls... or just look up any botany or plant biology books at the library... they have some really good information.

Read that co2 can be benefitial 4 da plant roots as well but kinda a hassle to hafta throw it in every few hrs. Gotta make it automated somhow. Anyways the good thing is i don't think u can overdo the dose.

i bought them 2. use them once a week.. and my plants are very healthy, is the possible that the roots absorb the co2 and brings it up the stem in to the leaves??:peace:

Dont know if anyone cares, but Dry ice= CO2. Drop a little in some water and it will make the dry ice (solid CO2) disolve.

First off, wouldnt you by doing this be creating carbonic acid... lowering the pH slightly? (may be bad for slightly acidic pH anyway).
Secondly, i feel like most of the CO2 will bubble into the grow area anyway thus increasing levels of gaseous CO2. But take whatever i say with a grain.

Thats what I was gonna say. A trip to Costco/BJs might be in order.
