Cover seedling for increased humidity?
krogorstarted grow question 7 hours ago
1. Does it make sense to cover the seedling with a cover (bottom of a plastic bottle) to increase humidity or should i remove it (e.g. for better air circulation)?
2. Should i switch on a fan that moves the air a little bit (pointing it above the plant)?

Unless you are in a very arid region, you shouldn't need a dome for a seedling. 20-30% rh might be wise to put a dome on and cut soem holes in it until it is an appropriate RH% for your temperature - vpd chart is a visual aid for this. You want a slightly slower rate of transpiration (i.e. lower vpd than for mature vege or flower) early on, but too slow and you impede growth. I've read different suggestions but .8-.9 is probably fine. I'm usually above that, and the impact must be tiny.
Circulation fan only needs to cause a little jostling of the plant. Definitely don't point it directly at it. A little twitch of a leaf here or there is fine.

Yes, seedlings like it humid and until they have popped just a bit above your substrate, you can remove it or cut a panel out even for mire air flow. I've done seedlings with no fan and they are fine but once they approach pinky-height (or your personal feeling as to when) their stems do benefit from that light breeze, like standing in the wind a little? But dont go crazy and dont run up your electricity needlessly. An half hour or an hour of fan here and there is enough when they are very young. A breeze here and there is beneficial for them though, more natural. Good luck, hope it goes great.

Is this Shell membrane crucial to life? Will this bag-seed Seedling survive?Will it survive? The seed was pried open with saliva and pruners once it broke soil. I see some brown (what I suspect to be) membrane that maybe needed to stay with the cotyledon.

Seedling leaves turning white, no true leavesWhy have my seedling leaves turned white? One of them sprouted 3 days ago and it’s first true leaves haven’t sprouted yet? I am growing in coco and perlite and watering with water and rhizotonic? Is it because I haven’t let the soil dry out and I’m watering it everyday?

Mould on seedlingThis seed was late to spawn. Now it finally opened, even if it's quite short on the soil. I can see a fluff of mould just below the cotyledons. What should I do? Can I save it or do I risk contaminating the rest of the plants in the growbox?
