Leaving for a few days, babies.

Ok this is what I am planing to due, tell me if it sounds ok.
I am going aero and I have 12 babies going from seeds. They have cracked and are about one - two inches tall (first leafs only). Sense I will be out of town I will not be able to water them and I was paning on leaving in the dome for a week. I thought about going ahead and placing them in the system but instead of running the system on a reg basis I would change the cycle to run for 15 min 4 times a day to moisen the rockwool. They will be in silica stone so the cubes wont be in direct contact with the sprayers so they dont get soaked.

So what do you think?

I know it is a bad time to be leaving but it just came up and I can think of anything else.

I personally would take them out of the rock wool and i put mine directly from the paper towel to the net pot with the collar never misted and only had the dome on a couple days and its like they blew up man im day 20 today and its like they were at 2 months in soil its insane but yeah if they are sproutlings they wont use much water so you wont have to top up i'd set it and forget it for a couple days i dont hover over my stink bud setup everyday damn im stoned
