Hello. I recently bought one of these hydroponic kits, and I was wondering if anybody had any experience using these?
I don’t understand what type of system this is. I don’t think there is any air stone to make put oxygen in the water.
thanks!!

Well Lavindo, if the system you bought is the same as the picture, I see an air pump, which runs to a 5 way splitter feeding 4 pots and the reservoir. Whats on the end of the clear tubes going into each pot? Nothing?
