Is a plug the same as the cubes I'm using made from rock wool? I think I might go more coco and perlite for more oxygen on these beans instead of soil with coco.
Well they do the same job, but the plug is made out of bark, and has natural beneficials. Rock wool.....I love it for how well it works, but hate it for the anti-green properties. Where does all the trash go? The throw it all into land fill way of gardening makes me feel kind of ill. Yeah man, if you go soilless, there are some big pro's, but there are also some cons...
pro's, you can water more often.....What you feed them in there watering, is what they get, since there is no nutrient in coco, or perlite.
cons, soil gives a good ph buffer, soil has stored nutrient, this gets used as the plant needs it. Soil usually saturates with water more, so in the unlikely case of plant abuse and you don't feed them for a few days "jail", they may survive!
There is many more variables but I digress......
