I dont know of any diagram's showing this persay but maybe this will help further explain the process.. LOL im not sure how these guys do lengthy pictorials so this may take a little longer just hang tight haha..
First of all i start with a germinated seed. I throw my seeds in a cup of water until they drop to the bottom of the cup usually withing 24 hours or so then they go into a damp papertowel which i keep moist for a few days to grow out there taps until they look like so... I crack the plug open and seat the taps in them like i already explained previously.Here's transplantation of the beanling to the plug.
From there they go to the nursery like so..
Until they look like this..
Dont worry about the stretch because they are being transplanted low enough in the pot with a bit of hydroton between the plug and the bottom of pot.Dont have a picture of a loaded one persay but its very simple if u think about it here's a couple pots before plug transplantation to the pots..
Set the plug right on top and fill the rest of the way just below the bottom of the leaves should be fine at least it always works for me cause ur rock does not get wet. The rock below the plug stays wet and keeps the plug moist.
In 1-3 days u should see this...
Once ur roots hit the water and feed for a week or so u should end up with this..
I used to transplant my seed plugs directly to the pots and hand feed them as well in the system. If u have to do it that way... Place them exactly the same (U wont have to hand feed!) and allow them to stretch a little and fill the pot like already descibed.
The whole time try to keep ur PH as close to 6 as u can.
This is why i begin feeding right away now. The presence of nutes in a newly established REZ actually helps the REZ PH get established faster (usually withing 3-4 days) it should balance out. But watch it daily and bring it back to 6 and allow it to do its thing.
There's really not much more to it than that.
I hope this was clear enough. Im not surei could explain it any better.
Peace.
