Mesh bottom pots or a few holes for roots?

I Do a hydro flood table set up! Is it better to have a pot with only a couple of holes on bottom to contain roots a little better or mesh pots and let them run.?I grow in mesh and roots end up turning into a long massive mane of roots shooting out the bottom.Im not saying a few inches,i mean close to a foot long.Im thinkin thats good is it? Do plants benefit from being a little root bound or should they be allowed to grow as long and as far as they want? I get great results with mesh!!

mesh:
also, try filling around your pots with hydroton to block light out from those roots that want to "run" and give them something to grow in..feed in..breath in...
i personally like the hydrofarm square black pots with mesh bottoms and slotted sides- buck 50 ea
cheers

sounds like mesh is the way to go. I do wonder if taller slinder pots is better than shorter wide pots?

I do want to cover my table so light cant get to the roots.I had lots of algae growing last crop.I will look into this hydroton thing.
