Hello The seedling will take light in through the stock at this stage. The light it gets now will stop her from stretching to much. Good Luck. Chuck.

More light now will encourage her to start growing and opening up. I would put her under it now, but careful not to place it too close, seedlings love light but kind of the way NASCAR fans enjoy car crashes-- at a distance.

Urgent need help what do u think?
Update on glue gelato, please let me know if she's alright, first week after germination and already had to change her soil since she didn't like it there and also had to place her on a solo cup with more perlite to increase oxygen in case she was over water or too much light

Germination how Important?
How important is the Germination period, and is it necessary to really worry about? or Do you just drop and let nature do its work?

Seedling not showing any growth
One of the seedling is not showing any signs of growth, you can see it in the picture (top left corner). Since this is an autoflower and it has already lost out on 2 weeks of growth I wonder if it is worth keeping it or use the space for another?

3 Identical seeds, 2 of them looking a bit weaker, same conditions.
Is anybody able to identify why Seeds #2 + #3 look a bit worse than #1 just from the picture? (Different Soil Color is due to me messing with the exposure, in person they look the same) Light: SD1000D 100 Watts Soil: BioBizz Light Mix Water: Tap Water without Chlorine

When to pot the seedlings?
Hi! When is the best time to plant the jiffy pellets into pots? They sprouted yesterday, and are doing nicely in my propagator. Should I plant in pots now and keep them inside the propagator or leave them a little longer? Or just plant them up & put them inside the grow tent?

Should I put these seedlings in the open, or leave in the propagator?
I've got these ladies into a 8cm fibre pot. Should I leave them outside the propagator where it is 40-50% humidity & 24 degrees Celsius, or leave them in the propagator where it is around 70-80% humid and around 28 degrees during the day?

Watering seedlings query
Hi there, How much should I be letting the coco dry out for these seedlings? I just had a failed grow due to overwatering the seedlings and I'm looking for some guidance. I know there's many factors, but I'm just worried I'll either under or over water again. Thank you!

Seedling not looking too well
One of my plants is a bit stunted compared to the other, and is yellowing and curling a bit. I've only been spraying down the top soil with water about once a day. Should I add nutes or possibly do a more thorough watering?

Why are my seedlings so leggy when they get enough light?
I added pictures from 4 days after germ and wonder why my seedlings are so leggy (~5cm). I already filled it up with soil and they would be 10cm by now if I didn't. First 2 days was 12-14 DLI and since yesterday am giving them more light than many guides say: 250-270 PPFD, 18 DLI
