What height should the water be between seedling and about 4 weeks? Im not sure if the roots should be in sitting in the water at that age. Seedling is in a floral foam block, the roots are just poking out. been hand watering until now. I think its time 2 use the bubbler system but not sure about the water height. Any advice would be great!
Water should be touching the bottom of the netpot when they are young seedlings and such. When the roots start to protrude from the bottom, lower it about an inch. Once roots are longer, keep it 2-3 inches below the pot from then on thru harvesting.
