Cloneing in rockwool with plans to transfer to soil

Hey guys this is my first post here sorry if its in the wrong thread or a duplicate.
I'm cloneing some g13 and Iranian diesel in rockwool and after they root they will be going straight into soil. What I want to know is after I soak the rockwool in 5.5 what should the ph of the water in the nursery dome/ tray be if they are going into soil immediately after rooting.

will be doing this today so a quick reply would be super awesome.

What I've noticed is that soaking rockwool in PH 5.5 water will raise the ph of the water in the bowl to usually around 6.2-6.5 depending on how big the bowl and how much rockwool your using. As long as the ph range is in the mid 6's you'll be fine. I water with ph 6.5 if I'm going into soil though.

I don't leave any standing water in my tray, I mist the lid if I need more humidity but that's it. The rockwool with hold water from 4-7 days with out issue no need for water in bottom. Just water as needed

I find cloning in rockwool really hard, but then I have nothing for comparison ive never done it before. The advice given is sound though. To add, I was always told fo keep the clones under a 125-250w cfl not sure if that tip will help you.

I've used rockwool to clone for years but my setup is from my own trial and error. I use a small aquarium with about 1 inch of perlite in the bottom that I keep wet continuously and a glass cover over the top with a 45 watt cfl a foot or so over it. I spray the clones and the inside of the aquarium with water once a day. I do have some that fail, so I always take 4 cuttings and pick the strongest to transplant for each one I intend to grow out. I keep my temps inside the aquarium between 75 and 78 degrees Fahrenheit and spraying them daily keeps the humidity high. I use dyna-gro cloning gel, something many say is unnecessary but it does seem to increase my success rate - that may be my wishful thinking though. You might also want to look up "scarification" - using a needle make shallow scratches or punctures where you want roots to grow. I've only used that technique with cloning gel, so it may or may not be a benefit without it. I think everyone has their own method to a certain extent, I found a way that works and stuck with it. Don't get discouraged if your cuttings die, I don't even want to think of how many cuttings I killed learning (FYI that was before forums like this - damn I'm old), but if I can do it so can you - keep at it and you'll get the hang of it, Good Luck!

Rockwool to soil should be avoided

never enough air in the rockwool is the noobs mistake

even if you are lucky and they strike

you will have to contend with fungi attack as root rot

use a diy bubble cloner or rapid rooters

good luck

ps the bubble cloner is 'fun'

vostok - I never had a problem with fungus or root rot using my current method, but the only time the rockwool gets really saturated is during presoak. The rest of the time the rockwool cubes only get what they absorb from the perlite underneath them. I have occasionally gotten some fungus on the perlite, but a good cleaning of the aquarium and boiling or replacing the perlite has always cured the problem. Thanks for the advice though, I'm always on the lookout for a better way. I'm looking into the bubble cloner.
