Hi all,
how long do you usually keep the dome on your seedling trays? Mine are working on their third and fourth set of true leaves. When do I let them get some fresh air and take off the humidity dome?
Thanks.

They do fine with no dome at all. Do you have very low humidity without it?

Depends on ambient climate but, once she has her 2nd set of serrated leaves, off it comes

Domes are normally used more for cloning to keep humidity up than anything else.

From seeds, I don't use a dome ever to grow plants.

I agree with the consensus that its best not to use it all on seedlings buddy. The climate will be more likely to rot seedlings than help.

Once clones have decent roots they no longer need to be kept under cover.

Seedlings want to be at the same temps and humidity right through veg.. Ideal VPD from the get go otherwise you shock the plants when you change.

I soak my seeds till the tails are right out so they dont need anything doing to them, hardly watering. If you were putting the seeds straight in the soil without soaking then you could use a humidity dome but you'll lose way more to pathogens.
