Hey Antics. Just went thru the whole journal and subed brother.
You had a question about coco and as you already know thats pretty much all I use. Don't know where you are located but biobizz coco mix is the best I have been able to get my hands on in Europe, but when I was back in the States I found out that Mother Earth Coco was hands down the best coco mix I could find. So if you are in North America (U.S. Canada) I would go with mother earth, 0 ppm every bag I used.
About transplanting: I have had to do this with a couple of my plants (1 ganja and the rest regular plants) the best method I came across was from and old time farmer.
1- lay a tarp on the floor
2- Water your soil until its moist not soggy.
3- get a friend to help
4- have your friend pick up and tip the pot upside down while your hand is positioned on the soil two fingers on one side of the plant and two on the other.
5- Your friend gently picks up the pot while you balance everything with your other hand and at last have your balancing hand direclt on the soil at the bottom where the pot used to be.
6- lay your soil and plant lying on its side on the tarp. roll it a couple of times with little pressure and a good portion of the soil will come right off without hurting your roots.
hope this helps if your up to it.
