Here some more advice for yea IMO i would cut more of all the fan leafs in half as there heavy and poor stems are getting the grunt of it due to misting etc
right after cloning a person should give all clones a good mist and dome then leave it alone not bothering them for like 3 - 4 days
99 percent of clone failure is from screwing around with them let them do there thing
what to look for when clone tray is under light , you need humidity in that dome so light distance is important to close and heat from light will disapate the humidity to fast .
So once under light check every 4 hrs the dome to make sure it looks foggy i guess white ??? then you know its all good , if not and dome is clear you will need to raise lights few inches higher till you get the happy sweet spot where dome holds its humidity
Again i stress let clones do there thing so all your job is for first 3 - 4 days is making sure dome is really humid ,
then after 3- 4 th day a person can mist daily i usually do it early mornings and late at night 2 times also allowing them some fresh air but putting domes back on and leaving them on for at-least 2 weeks ( wipe dome and re mist every time )
jiffy pellets work great soak them big time then gently squeeze little of the water out use tooth pick make a good hole and your good to go
you might want to look into bigger dome there as jiffy domes are shortys in height . great for very small cuttings and seeds
I have 100 percent clone rate success, got away from the gels high priced clonex etc and went to cheap old shultz #2 powder and never looked back
