Thanks DP for that link. The author seemed to have a favor of coco over soil though.

bbunlock - 11 litre pots are a little big for young seedlings. No worries though. With coco you have got to keep in mind that YOU will have to feed ALL regular nutes and micro/macro nutrients along with supplements. Tap water is not the best to be using...... Like the link said, coco is closer to hydro than it is to soil growing. Best advice is for you to read read read and then when you are tired of reading, read some more.......
