fair comment. My roots however are not exposed so I would expect that the intake of C02 would be via the leaves.
Here's the caption on the Hydro shop website:-
Fizzy CO2 tablets with extra slow and gradual release of carbon dioxide.
They provide plants with the greatest quantity of CO2 they can absorb through their leaves.
Can be used in the nutrient tank but we recommend using the CO2 in a separate bucket of water in your growing environment.
