nice setup
i read your other thread also about drooping clones man just wanted to share what i know in a bit more detail.
1. my clones go into the holders an the stems are not in the water.
2. water is clean tap water (from a well) and i dont change it till they are done rooting (cause i am lazy)
3. i have never used any rooting hormone or neuts in the water.
4. the bubbles (or spray for your case) hits the bottoms of the stems. ( do your net pots interfear in that process? )
5. i dont mist em or anything
6. when i take the cuttings i put em in a glass of water till they hit the cloner
7. i put em in a windowsill or a dual bar fluro 18 - 24 hour light
8. forget about em for 10 days or so
think i am on day 9 now and 7 / 8 of them have roots / nubs and are ready for transplant.
ending thoughts lots of these experts have had lots of practice and tweaked everything to perfect for them but simple is always better, hell i normally just sit my cuttings in a jar of water in a window sill and in 14 days they all root 100% i just started this to play with and it seems to shave a few days off lol.
but i do like your cloner cause it could be so multi purpous.
here in a week or so i am going to post my grow room setup whitch is very minimalist but effective you might like it too.
but i am rambling now anyway i hope your clones do well just remimber with mj less is more
edit: yea i do seeds all the time they shouldnt come out yellow typical questions would be are you using neuts or soil with neuts in it already ? heat ? light ? are they all doing it or only a few ?
