I told you I have 2 wells...They seem to do better with the one that is pH 5.4 vs 6.8
When I clone in water I do not put anything in it.
No Clonex or root powder/hormones.
The only ones that I ever lost doing it like this were ones that were on weak stems and the leaves had either some sort of deficiency or tip burns already.
I have joked with others on here and called it my 5 cent "hydro-cloner" system.
I have always thought about building an aeroponics cloner, but I think I will stick with individual cups. The reasoning for this is because I have seen too many threads where people lose the whole batch when something goes wrong. Also the pump makes the temps run high and that makes a perfect breeding ground for pithium and algae. Sure you can use additives to keep the bad stuff down or you can use a 3 cent cup per clone and get the same results...I have had some start making roots in as little as 5 days. Usually they are rooted in about 14 days and by 21 days some get very long.
I use my Fiskars micro tip shears to take the cuttings. I leave the tip and 2 leaves and strip it down from there. I use a sharp paring knife to make one scrape down the stem. Not too deep mind you, but I do scratch a little off. I then put the cutting in a big clean cup filled with water and make a steep cut under water. Some say 45 degrees, but I make mine a little steeper than that. Then I transfer it into a cup already filled and waiting. Be sure it is long enough to have at least one node well under water. I have used 3 oz opaque plastic bathroom cups with great success. They no longer have these atwalmart and now they are slightly bigger at 5 oz. Very cheap cloners. Change the water every 3 days and you won't have to worry about algae.
During my testing, I noticed that the roots always formed on the other side that was not scraped. I jumped to the conclusion that scraping did not help and was not needed. The next few I did without scraping and they took a lot longer. I am a believer that scraping does indeed help.
I am testing something different this time. Remember my test 2L/DWC with just a smidgen of perlite at the top ? I bought some net pots and collars and have some cuts floating in 5 oz cups. When they root, I will suspend them in full size 2L's without any medium....I may even journal it.
