Hey all! im sure you all know about the 55 gallon flood and drain system i have going on, but i was thinking about expanding now.
We have a desk that was almost going to get trashed until i noticed that it would be perfect for an nft system
My questions are,

How effective is nft at growing compared to flood and drain.(i understand some plants arent very good with nft, but what about the ones that are?)

If instead of using its own tank, could i connect the nft system to my current 55 gallon that is running to my flood and drain?

If i were to connect them, would i still need a filter or would the grow bed for my flood and drain suffice?

Thanks
