propagating cuttings via hydroponics over winter
Hi, I'm trying to propagate some perennials from cuttings just taken, using hydroponics and grow lights.
I'd like some advice of the feasibility of this experiment please!
Pictured below is my propagation unit with the cuttings; the lights are on 15 hours a day and the fertilizer in the water is apparently NPK 5-3-8 with micronutrients. The cuttings are sitting in about a centimeter of water, surrounded by porous sterile stone, soaked by capillary action.
My hope is that the roots take, I can pot the plants on, sun under the grow lights for a while, then store in the conservatory over the remainder of winter.
The plants in this picture are from front: nepeta, salvia, hydrangea.
Has anyone tried this method with success, or have any advice to offer?
