I am also growing pumpkins in my DWC units. They are really thirsty. I'm not sure how much
nutrients to give them. I'm just using about 6 tablespoons of Maxigro every 10 days or so. Already have some tiny pumpkins starting to develop.
It is another story with these strawberries. I only have a few in the tower right now and the water is going somewhere. This morning I did some tweeking on it, so I hope it will now use less water.
