Best RH Control for Seedlings- Whats Your Favorite Method????

I want to know how other growers prefer to control the RH for their seedlings (without buying a dome or device) I want to use something I have laying around. (water bottle, zip lock baggie)

I'm starting a new grow from seed and plan on using the water bottle method to cover the seeds for RH control (didn't monitor RH last grow) then poke/cut holes each day until they are hardened off.

1. Is this really the best method to use considering the cost? (pretty much free)

2. How many days do I leave the bottle fully closed before I start poking/cutting holes in it? And how long after that does it take to fully harden?

I don't worry about it with seedlings.

I soak seeds.
Plant seeds.
Water accordingly.

.. is this a real thing that people actually do?

lol... surprised you havnt seen it done since its like.. EVERYWHERE.. but ive also never used this method before.. but after having a few seed issues figured it might be bc my humidity is so low

No need for a dome with seedlings. They're used on cuttings to stop water loss from leaves when they have no roots.

soak seeds > plants seeds > water.
it should be that simple not all that extra stuff lol i've never seen this method before

As above, really it's a clone thing. TBH, Iv had more issues using a dome as you can get too humid and causes a mold or fungus that kills seedlings,

Keep the soil medium damp and that should be sufficient.

Otherwise, use a dome.
