Plants that are grown hydroponically at a nursery nearby: Arugula, Watercress, Sorrel, Swiss Chard, Spinach, Red Oak Leaf Lettuce, Green Oak Leaf Lettuce, Red lettuce, Bibb lettuce, Basil, Cilantro, Chervil, and Rosemary. The grower did tell me he was having trouble with the spinach bolting to seed too quickly, something to consider.
Offered by Toni.
The spinach bolting to seed indicates either too much light or too much heat. It is very good to hear that the other vegetables and herbs are being successfully grown hydroponically.
Offered by Ron.
His temperature is too high for the spinach. He should separate them if possible and keep them cooler (like at about 65 or 70 degrees).
