i have seen a few ebb systems and i just don't get! i understand it but don't get it.
fill the lower bucket with nutrients, put in a submercible pump with a tube that leading to an upper bucket with clay stones that every once and and awhile gets a splashing of nutrient water. perhaps it's my misunderstanding of how the clay stones hold and retain water, then your seedlings grow in this round clay stone mixture that every once and a while getting a little shower, then a return hose allows the nutrient water to flow back into the lower bucket, with a timer on the pump to activate it a couple of times a day so your seedlings don't dry out and don't forget the air pump and airstone for the nutrient mix to keep that mix oxygen rich. the pictures and results are evidence that it works, i just don't get it.
i do get aerophonics and have 2 systems working right now and just bought the accessories to make 2 standalone aerophonic stations as my fatalii & scotch bonnet plants have become so large they are shadowing my other seedlings.
plus the cost of the clay pellets, i just about shit when i saw the price of the stones(think it was $35 for a bag), yes one could say "but they are reusable" but i reuse my promix - maybe one day i will give it a try.
and yes, you would still have to incorporate lighting.
