We don't do anything special to grow our chillies. Start the seeds off in a seed sprouter, then into a seed tray, pot on into 3.5" pots and into bigger pots when suitable - and when there's room for them. Some of last year's plants are in the propagator in the greenhouse and are left to survive or die - with some watering and the occasional opening to the elements for a while. These are some of this year's Nagas, with about forty more in seed trays and more in the sprouter. We also have, potted up, a couple of dozen ShineyHybrids with more in seed trays and sprouter. I'm only growing so many Nagas, if they survive, because I have a market for them. Everything is hit or miss. That's been our growing policy for 50 years Gradually, over the years it has become more hits than misses.
