Hi, I'm just planning my next system. Couple of questions about nft pls.
1 I'm planing to fill guttering tubes with clay balls and position these vertically above the tank. I hoped to cut small regular holes to expose the balls into which I would grow my plants. Can anyone suggest the volume of these per tank ? Same as a grow bed do you think ?
2 would I need to trickle the water through continually or every so often ?
Any suggestions about the validity of this idea would be warmly welcomed
Thanks
