Just this guy, ya know?
I've only run pure coco or soil, I don't have any advice for rockwool in soil sorry Doesn't really sound any different than starting them in a peat plug though.
I'm trying to heed your warning on the over watering. I was beginning to worry when the tall seedling fell over. The seedlings are in rockwool cubes in the dirt. I've never had an Issue over watering rockwool. My DWC top feed system runs four times a day for 15 minutes and the rockwool stays dry enough that I've never lost a plant to that particular issue. I've also been trying to flush the soil as I mistakenly purchased soil that is hot.

I would avoid clear cups in the future. Dont want light getting to any roots. Side note, on this run im on now, i germinated in rockwool like i did last run but this time instead of going straight into 1 gal fabric pots i tried out the solo cup method then transplanted to 1 gal pots. Not a fan, think ill stick to rockwool cube --> 1 gal. Too easy to over water without the drainage and ability of air to get through the pot with a cup vs a fabirc pot.
Hi fixer
I like to add h2o2 when I germinate or when I root cuttings. When they are strong I stop using h2o2 and start with mycorrhizae, ACT and other protective life. I live surrounded by rainforest. Since im using h2o2 I can germinate 90%, before that it was a PITA rooting or popping up any seed.
I've used ClearRes/ResClear? Which is no longer available. I'm going with Mycos/Azos with the clones. I've used h2o2 for root slime. What ratio of h2o2 to water do you use to germinate?
The more pics you post, the more they look exactly like mine . good stuff, those seedlings are looking very healthy. Shouldnt be long before a transplant at that rate!
I’m on my phone so it’s hard to see the pictures clearly. But as to the cupping on the first picture, that’s generally heat stress, overwatering will have leaves drooping down. And to the hole in the leaf, you might’ve hit the leaf the wrong way and broke a hole into it as I’ve done a couple times will watering. Just a possibility.
Few things: I notice you have no window to exhaust air. Are you supplementing with c02?
How and what did you use to make those drain tubes on the tray? I don’t like mine dripping into a 5gal bucket cause the drops splash out onto the floor surprisingly.
And lastly, just a suggestion, build a little platform for your water tank(s) so they are up off the floor to help keep a more stable temperature. Casters will make them easy to move if you had to when they are full. Unless you’re using an aquarium heater then disregard.
