I completely forgot to ask that. Are they in rockwool? Cause if they are, THAT is your problem.

So the rockwool is killing them?

It’s not drying out, it’s drowning lol.

I agree . Turn off drip lines and hand water until roots begin to show out the bottom of netpot

 

[Budley Doright]

they are drowning. can you put the top feed on a timer or just hand water 3-4 times per day?

That may even be to much, I was a two a day and turned it to 3 and started to get very slight tip blotching, back to two for a bit lol. It’s a bitch getting it right with the sponge we call rockwool, most of the issues at the seedling stage are due to over watering .

They are in rapid rooter cubes. I set up a timer and started to water 15 on then 30 min off. Here are some updates pics. Still no roots tho.

even if you meant 15 seconds that's way too long at any stage, but especially at this stage

Consider hand basting until they get 4"+ tall

Bro they’re just flat out too small for the system right now. I run my seedlings in 3oz mouthwash cups with coco and fill it with roots then when it’s bigger, take it out, knock off excess coco, and bury the rootball in a net pot with hydroton. 3 days later, this.View attachment 4106821View attachment 4106822

What brand/size tote is that. I can’t find a low profile size tote like that that’s built like that. Most of the totes that I find are just too large (15 gal and up). Hdx totes are great but I have never seen a tote that looks like that. I’m thirsty for that tote ,..if you can’t tell

I haven’t used rapid rooters but root riot cubes yes and they retain water as well.

Your stems are most likely rotted. You should have roots by now.

Dial back your feed pump intervals to like 15min every 6 hrs or so if you are stuck with a 15 min increment timer. Let those rooter plugs come up for some air, they're drowning. I'll bet you see root growth within a day or two.

I start at two floods a day until roots appear then increase.

My best roots ever (aside from when I had hpa dialed in) 3 minutes on and ~ 40- 60 minutes off; depends on ambient temps
