i run 200ish ppm (or .4ish ec) in my spray cloners for cuttings and small rooted clones, i would think that should suffice for dwc as wellWhat ppm do you run when you have clones in DWC?? I take my cuttings and put the bottom 1.5 inches of the cutting directly into water with nutes.
Does the bottom of you're cuttings sit directly in the water?? The bottom of my cuttings about 1.5 inches sit in water and above that is the neoprene fittings and above that is the clone itself.Are you using tap water, RO or something else? If you're using tap, well, or spring water your ppms may be higher than normal. It also really depends on what you are using as a cloning solution. I use RO and keep mine to about 500. I've had it to about 800 and still had success. I use CloneX Clone Solution 1-0.6-1. I'm not sure if you can go this high with other solutions. When the plants establish roots, they will yellow fast if they don't have the nutrients. You really can get away with using tap water and no nutrients although I would add something once the roots establish.
Make sure you have a somewhat decent air stone and air pump. They are not that expensive. One of the most important things that is easily overlooked when cloning in hydro is you need to keep a lot of oxygen in that water. Air stones make a world of difference.
It looks like you're water is low?? The bottom of the cuttings aren't in the water?I use a little DIY Rubbermaid tub to root cuttings pretty much the same as what you are doing there @Meast21.
I use RO water with about 150ppm nutes and a dash of peroxide. A little bit of all 3 parts of the nutes with a little extra Bloom. I've rooted cuttings in the DWC tub with over 1000ppm so I don't think it's a critical factor.

It was warm and I left them too long in there and some root rot developed but I put them in pots of soilless and they did fine.

The ends are in the water when the lid is down but they probably don't need to be. The popping bubbles act like those ones that use spray heads and high pressure to blast the stems.It looks like you're water is low?? The bottom of the cuttings aren't in the water?
Don't really need too. I have a cake lid that is almost the perfect size to make a decent dome and I'll spray the inside of it to keep the humidity up to around 90%. They might droop a bit but soon stand up. More leaf is faster growth once they get some roots and get planted in a pot or tub for DWC and get under strong light. Can have 21 cuttings in there if need be.Looks like you don't cut the leaves of the clones either??
