Found you!
Maggie, household humidity may be too low for your young seedlings, they prefer up to 70% now and down to around 45% during flower. I would definitely grab a humidifier until you get set up or at least a hydrometer to see where you're at. Do you have any kind of grow light at home to use where you could stick her in a closet, perhaps?
Nutrients...huge role! Please check out
@Prescription Blend, they are very easy to use with soil and have amazing results although I have heard good things on your choice.
Spacing lights and temperature controls. See what kinds of vents you are working with inline system, exhaust. Seedlings like 24-30 inches generally from an LED. I use
@Mars Hydro also in there FC4800 unit. I'm sure they would love to welcome you here and chime in!
Please lmk how I can further help you get set up, now knowing you are a fellow grower and in a tent (soon) with Mars Hydro, we have a lot to talk about! Good luck and glad I found your journal, now you just need to link it to your signature so everyone can see it, too!
Edit...just saw they were 5 weeks old already! Do you have pics?
