Hydroponics is really only of use for growing cropping plants indoors under artificial lighting. If you want to raise any kind of cuttings, the most important thing to provide is bottom heat. That could easily and cheaply be arranged by having a temperature controlled heated propagation bed (they are easy to make yourself, if so inclined) or a heated propagation mat You then place the cuttings in pots filled with a mix of compost and grit (or perlite), stand them on the heated bed/mat and they will root in no time. Once rooted, you would then transfer them to an unheated greenhouse or coldframe to grow them on. When large enough to plant out, they need hardening off by placing the pots outside during the day and bringing them back in to the GH or coldframe every night for a couple of weeks. This allows the plants to slowly acclimatise to outdoor conditions.
