When should I transfer these plants?
I am taking my first stab at hydroponics, and these are my first plants. The two in the back are cucumber and the two in front are roma tomatoes. My plan is to use the tote to start plants, using a weak general purpose nutrient solution for younger plants, and then transferring them to 5 gallom bubble buckets with a customized nutrient solution once they get larger. My question is, how large should I let them grow where they are before moving them?
