so you recommend aerating the water, 24/7 for the full two weeks?
Certainly, yes! Or if not, replace new every few days with the same temperature water to prevent shock.
For the price of an Airpump and a stone, its a no brainer when dealing with a lot of cuttings on a budget
What's the best soil to drop rooted clones into. Normal promix?
Now your done, simply stick em under some low wattage lighting, and wait. After around a week or so, you can start lifting the top cup and checking for roots. Takes me anywhere from 5-15 days to start seeing 'em.
In regards to changing the water, I've never had an issue with keeping the same water the whole time. However, if you do feel the need to, I do recommend waiting 5-7 days before the first change.
The only time I have had issues with this my water, s when I changed out the water in the first few days. Water got all nasty, clones didn't root. Only did this one time, so not exactly a clinical study, but good enough for me.
I think the reason is akin to why some hydro growers wait some period like 10 days or two weeks after setup before changing their reservoir water.
If I recall it allows a protective biofilm (some kinda algae/bacteria?) to build up over the cuttings/roots.
What I do now is after about a week, I will take a peek at the water in each cup, if I see one that's starting to look funky, I'll switch it out, but other than that I just leave em.
