I can’t tell anything by the picture but I wouldn’t grow in sunlight at all, just complicates things and makes more ways for things to go wrong. I would stay in the grow box / room
Yes, in fact it can kill it if it’s never been exposed and all of a sudden gets too much there’s a process called hardening off that must be done to all vegetables and plants
The sun is a fine line to walk, I feel it’s best to just keep it under the lights you’re going to use …I said that in another thread earlier today too !? LOL
Ahh! There’s the information! Weak sun would cause it to stretch and that could cause it to fall over, and I think someone else said damping off already too
I can’t see the picture but that’s very likely what happened now that you mention that. Do yourself a favor just keep them under the steady grow light, keep everything steady and constant that’s what these plants like !
Here is a thought. Is there any chance that the rapid rooters could have absorbed something while in storage ? You may have bought them new but just a thought. I’ve never had good luck with the peat things that swell up, same symptom as you. I just figured the ph of them was not good or something. I’m sure that I was doing something wrong cause others have good luck. (I’m far from a pro)
When using the rapid rooters you should soak them over night in pHed water, that way you won’t be wondering “was it my rapid rooter?”. I think damping off is your problem, as well as stretching from weak sunlight. They want good light even as a seedling, just not intense light when a seedling.
It’s why most people will keep seedlings under a T5 or CFLs, they give good light but it’s not intense at all so your lights can be very close to your seedlings, helping to avoid the stretch problem.
I have the bag of rapid rooters stored in a closed ziplock bag… Stored in a cabinet.
I’m wondering if that was a good idea, seeing how the rapid rooters are wet, and it being closed… maybe it’s molding?
I agree with treez on the rapid rooters, I think they’re great for clones but I don’t use them for seeds anymore, I didn’t have very good luck. I use a 50/50 perlite vermiculite mix in 2 inch pots
I also soak my rapid rooters in pH’ed water, but not overnight, just a few minutes, I’ll be using them tonight to take some clones from a super cheese and a skunk#1, I’ll soak them in my super-secret cloning mix LOL!
-good luck
Edit: it’s a super secret mix only because I can’t remember exactly what I put in it the first time LOL
Everything I’ve read, if it’s not sterile, there are molds and fungi present…in the air, on stuff…waiting to take advantage of conditions beneficial to them. It happens.
Leaving wet rooters sitting in the dark could be the start of a science fair project, good they are cheap and unloved
