Seed becomes half cotyledon and half... seed

This is really strage.
One day my green gelato automatic seed decide to sprout in my pot, it looks like one of that stranger things plants dog, but ok it will gradually become a double cotyledon I suppose, it only has to turn green and split.
But I was only half right, in fact the day after une side of the seed was a cotyledon, and the other side was still a seed, preventing the plant from growing other leaves.


Genetic: Royal Queen seeds - Green Gelato Automatic (2020 seed)
Growing condition: 20l pot filled with Bioterra by Biocanna, moist but not dripping wet, temperature between 19°C and 23°C. No light until coming out from soil, then Viparspectra par450 at 40 inches from plant.
Indoor, no grow tent.
How: I placed the seed without touching it in a glass of water (clean water, tap water, but clean, I drink it, we are in mountains) for 6 hours, then under 5mm of soil in the pot, managing it carefully with cotton fioc.

You've got to pick of the little piece of membrane that's holding it together. Those little green leaves are satellite dishes for the sun they need to be exposed to the light for the plant to continue to grow.

It just came out, but the half white seed cover the other leaf, and its difficult to see, but it seems that also the 2 first real leaves are white and still made of “seed”

Deeper in the soil would have been better - that way the action of it pushing through the soil pulls the seed casing off.

Anyway as TakenByTheSky says you can carefully ease the membrane off with a cocktail stick or similar.

I had this a few times and yeah you can either gently gently gently remove the seed casing, or cross your fingers and hope it falls off naturally.

What he's talking about isn't the seedling struggling to push out the shell. Most of us have had to deal with that frustrating issue. He's showing us the root shooting out of the 2nd white cotyledon. That is weird, haven't seen it before. It's a mutation, I don't know if you could force a seedling to do it. Most would die before they managed to shoot a root out. Must be a mutation. I'd consider burying it up to it's neck once it sprouts a stem and a couple more leaves. More roots can only be a good thing.

I don't often bury plants up to their neck, a couple times I've fucked up and gotten stem rot at the soil line. Most of the time, especially with vigorous outdoor plants, it'll do what your plant's doing. Start sending new roots out of the nodes instead of limbs.

I've got a super stocky seedling. Maybe the stockiest plant I've grown. There's almost no separation between the cotyledons and the first two sets of true leaves. Every time I transplant it I busy it up to the 3rd node and try to un-bury it again. It's certainly going to end up buried to it's neck. It's a promising plant, very bushy.
