Yes I did buy new trays domes etc. I bleach everything before using it anyways. Just started having problems with plants getting moldy, dying, taking forever to root for some reason. Couldn't figure it out. Went to the aero and had roots in 5days on root horny strains. Now I can literally depend on the fact every cut will root within 10 days usually 5-7. It's never taken me longer than 10 days to start seeing root growth. I just set it and forget it. Add some hypochlorous acid every 7days and I get wicked thick white roots Everytime. That's why I was recommending just biting the bullet and buying one but everyone is diff and will do things their own way so no harm no foul. At least op has some info if they change their mind down the road I guess.
