Ok so I want to add to this conversation. ( Keep in mind I'm not arguing or disagreeing ) I use the 72 site domed tray with vents and an t5 .
Root root cubes , clone x, and place perilite between tray and liner. I use a solution of water, ff kelp me kelp you, and super thrive , I place the solution in the perlite . I prep the clones by trimming to 4-6" ,trim leaves , split stem 5/8" , gently scrap stem , apply clone x , then I split the rooter cubes and place clone 1" deep . I place clone / cube combo in tray , I then place a single clay pellet beside the cube to squeeze the cube tite to the clone. I mist the clone every 3-4 days lightly .
Here are a few side notes.
Squeeze the water out of the cubes before you start.
Mist dome not plant once a day
Use aquarium temp gauge inside dome , the peel and stick kind.
Keep vents closed for 3 days
open vents 25% days 4-5
Open vents 50% days 6-8
Open vents 100% days 9- ........
I use RO water with a little Cal/mag.
And so far I have 100% success rate.
