24 hour lighting

[Notkeif]

First time growing indoors and I have autos under 24 hours of light but I recently read that isn’t ideal so I’m planning to switch to 18 or 20 but should I switch straight to 18 or gradually decrease

That is a good question and mostly up to you. I would shave off a hour each day until you are at the time you wanted. dark hours give roots time to grow or something like that if I'm keeping it simple. goodluck!

Appreciate it man

This happened in 2 hours when I came home from work the cubes felt dry so I gave them 15ml of water and I came back in to set the timer and it looks like this I guess it was over watered

Maybe, I'm not a rockwool expert but i leave mine sitting in water for days until i see them pop up then i put them in a jar/bucket with the water level almost touching the cube, the clay pebbles wick it up so it stays wet, i don't know what happened to yours.

@Mañ'O'Green what happened here?

That is called damping-off. It is caused by the germination materiel remaining too wet. Rock Wool will wick to 100% moisture content. The roots cannot get any air and drown. Even my 6 inch cubes will do that if the bottom remains in water. I have a special cube holder that is made by GroDan to hold starter cubes up for air flow. I always have one cube in the tray that does not have a seed in it as a control. When it gets light they all get watered including the control that dries out at the same rate as the ones with seeds. I do not want to lift the ones with seeds until I take it out to transplant. The roots are often growing out the bottom and I do not want to disturb them.
