Nice job tokin, tidy & clean.
Until the cuts have some roots showing, I always keep them submerged about 1", once roots are visible, I lower level so the roots dangle in the solution. Watch for them knitting together, I have had sweaters less tight than roots left too long in the cloner!!
G13 mentioned lights, the T5's are a bit overkill until roots are established, they dont need much light until new growth appears but they will certainly work, just watch heat. I get good results from a 13w single tube 2ft t5.
Just a point about solution, yes, Clonex is great, I use 1ml/l mixed with ph'd water, no nutes needed until roots show. I found no nutes rooted faster than with nutes but experiment to find what works for you.
I love DIY projects, so much more satisfaction than handing over cash for someone elses work.
Green mojo to get them roots growing. W
