That's a bit of a loaded question. As far as having to, no, the plant will grow. However you may want to for the plant to flourish. You can grow a plant in pure worm casting if you wanted to, but it's not a great idea. If you want to be lazy you should look in to something like Kind soil. It should only require water.
Gd'day Stoners, Fuggzy, Some background. I made my last 2 grows and my present runs in worm compost right from the worm farm. With the exception of 2 of six now, the 2 being the weirdos I showed here yesterday, they have all thrived. I've been waiting for the shoe to drop, the down side to appear and maybe it has with the freaks but maybe not. The jury is still out on their cause. What have you learned that I should look out for? I use nutes and mix in perlite. Other than that its pure.
