Just a quick question. Is Ona gel and Liquid safe to use directly in a grow tent? Or are they meant for the outside? Right now I have liquid and following the advice I saw in another thread, I made a plastic container and put a computer fan in the top of it with holes on the side of container. Filling the container with ona liquid and water, while using the crystals to soak some of the dirty water up. I have an incoming fresh air vent as well as a scrubber at the top of the tent. But want to add something else.

Will the plastic container with the ona be safe to use right inside the grow tent?
