Humidity dome NEWB question

Sup fellas, well i finally got my seedlings a friend poped for me . I got them under a 600 watt hps dimed down to 200 watts.

what are the ideal temps and Rh for them to thrive?

Any info is greatly appreciated, thanks

Ohh , they are about 4inches above dirt at the moment

Im getting 49% rh and about 82 f*

If they above the dirt there is no need for a humidity dome. All that will do is dampen them off and kill them for sure.

Ohh shoot really?

this is what thy look like. ive only had them 3 days now. figured they needed humidity

Rooting clones need the high humidity. Seedlings can dampen off and die with high humidity.

Cool thanks ma man

I dont think humidity is your problem with your set up.. . i used seeds as well and have maintained a 60-70% humidity for the last 4 weeks in my 4x4 tent and the plant are doing great. They like higher RH during veg and early stage but looking at them the stem seems very small you need some airflow around them so they beef up naturally to resist the wind .. which is the issue with your current set up id aim for 50-70% RH and 70-80F temp a bit outside those ranges would still work for veg.. in flower you dont want over 60% RH so more like 40-50% range and temps a bit cooler usually

cool thanks for the input. stocks do look small , and seems like the plant just wants to shoot upwards... ill add some wind to the stock

If you have extraction sucking air out of your tent then thats enough and wind is not needed.

Most places in the world have adequate humidity levels you need not bother checking or changing.
