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?

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

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,
