@Lazerus00 I tried one of those TurboKloners (not sure if you remember), but I was definitely not happy. Not at all saying they are bad; though for my situation and bad habits (lol), it's not for me. If you use a style like that I would HIGHLY recommend R/o water as the base.......unless your tap is city (with Cl).
There are a whole host of problems that have a higher chance to occur with the pump / nozzle type aero cloner; as compared to other methods. I would also highly recommend having some Chlorine Dioxide tablets around. I did test a 2ppm sterilization in mine and it worked beautifully.
As far as the pump needing to be on 24hrs; Total hogwash. In fact I would easily argue that 24/7 pump on is actually worse (from chance of things going wrong) than it would be with a timer. I tested with "off" times from 5 min to 1 hour. I now have the unit running with 45 seconds on and 1 hour off. Don't take just my word for it; Jackmayofficer also ran 1 hour off times and noted better results too. One hour off even is fine with brand new day one cuts.
Once I pull the remaining rooted cuts out of that system it will be shut off permanently, so i can test the new method I've got setting ready to try.
I guess for me, and just for me; I don't tend to do much maintenance on my cloners (my diy bubblers). If I change the water once a month, that is considered quick. I don't ever adjust the pH, just slosh some water in when it gets down half way. Also, very often I have to leave cuts in the cloner for as many as 3 weeks after rooting. So, my setup also has to allow for growing beyond rooting....again with no maintenance / care.
-So any cloner that I can do maintenance only once a month, get 100% rooting and can leave cuts for several weeks to themselves....I'm all for it.
**A note with this, if anyone has interest. When I setup my new bubbler I tested all the different plugs (if you remember). Root riot, rapid rooters, super starter plugs, rockwool. I did notice rockwool rooting fastest on the first test, however. Long term (i.e. time after rooting); the rockwool really suffers with salt buildup. Again my system is always blowing moist air through the medium, so this scenario can easily be exacerbated. However, rooted cuts left for 3 weeks; barely grew in rockwool, but grew 12" with the other mediums. As such, I'm using the rapid rooters from here on out.

I guess also it's interesting about high male percentage. I've recently noted that I have the opposite issue and have been wondering why. If I count all the newer strains that I've raised in the last 2 years; I have an 85% female to 15% male ratio. The one cross I did with my old strain bullrider; resulted in a 65% 35% ratio, so not far off from normal.
-I have been wanting to ask why do newer strains seem to have such a high female percentage compared to old?
-Also I notice that with old genetics hermies were rare and went full on hermy when they did show. It seems that newer strains have a higher chance to hermy, but only do it "marginally". I wonder if the higher female chance somehow relates to the higher hermy occurrence as well? You know with nature always trying for balance n' such.
@Lazerus00 for me, with males, there are a couple things that I tend to focus on early; so as to not get a ton of males. It all very well could be in my head lol. Basically though, I tend to run on the dry side compared to most; however I don't let a plant get near "droopy" before sexed, though somewhat close. I definitely would not want to run them totally and evenly moist during pre-sex. With nutrients I try to keep the leaves a "medium green"; not dark green or light green. I do not want to "crank" nutrients as well in the pre-sex stage. Suppose I prefer to keep them in temps below 80 also. Finally, I do not attempt any training during the pre-sex period either.
