This thread is killer! Question for you, master seedling grower: I’m about one year into my first deflasking of 16 OZ-refugee fairrieanum. They had stayed a year too long in the flask. I got them all out and so far have lost only one rootless runt (I cried anyway). The seedlings were very difficult to separate, which I did anyway before this forum taught me that I should have given them time on one big clump first. They were also very leggy and I chose to respect their root/stem lines anyway, so they’re kinda tall. Some suggested I repot them deeper but I just couldn’t bring myself to disturb them again. Well, here they are now. I was waiting for the mix to tell me they needed repotting but the plants have come through a Chicago winter happily, watered twice a week with RO/K-lite, sometimes KelpMax, sometimes Cal-Mag added, pinch of oyster shell twice in the year. I never let them dry out and mist most mornings with RO. South/southeast windows. One seedling is very runty but I keep pulling for it. The rest seem hearty enough to me, if leggy. All advice appreciated. I had been hoping to see roots through the clear soup container and yogurt cups but so far I really don’t.
the seedlings look healthy and you have got them to adapt to your environment, with minimum loss. I also deflasked a fairrieanum flask for the first time a few years ago and I took a similar pattern to yours. I possibly could have kept them a little wetter, but like all my seedlings treat them all the same. To be brief, I always put in single pots, to avoid any possible contamination. I monitor daily, feed kelpmax only for a month or so, then feed very low for around 6 months, keeping the medium of precision bark/perlite damp at all times. The aim is to get the seedling roots. I keep them on a heat mat in low light for up to a year, thats it. It may take longer than normal but the seedlings look healthier with this approach. When I do repot, I always "pot on" to avoid disturbance to the roots if possible. I possibly agree that to keep the whole flask together for several months may lead to better stronger seedlings/better roots before separating, but I have yet to try that, maybe next time.
Your seedlings have done great so far, so you could carry on a for a while as you are. You could also split up one of the compots into individual pots to try out first.
