I put together a vertical tube after viewing Youtube videos. I'm using 2" pots and Rockwool. I'm a little disappointed that water drips from some of the pot cut outs. If anyone has feed back on that problem, I'd like to hear it. My next tube will have a change to correct that. One thought I just had was maybe my pump puts out to much water. I'll see if I can slow it down. It goes through 5 gallons of nutrient solution in 5 days.
I have the tube in a 5 galon bucket with the pump, when refilling I noticed a green mold on the sides of the bucket and the tube, I'm sure some of that would not grow if I kept the bucket full. Is the green mold something to be concerned about?
I started late in the fall, just to get some experience. My germination rate was poor, but I have 8 or 10 plants and they are growing, some were a bit spindly when moved to the grow to, will need healthier sprouts next year I have mostly lettuce types, just transplanted a basil plant.
PS, I tried to attach a picture, twice, but it didn't attach. Any hint?
