[APD] Re: dirt, moderate CO2, and moderate light
RH: "What "long term" problems are you reffering to? Perhaps it would be
more helpfull for you to be more specific."
Just scrolling through the Walstad forum list of posts, if you stop and
read about any thread with over a dozen or so posts, the subject is mostly

hydroponics than to growing houseplants in dirt, if you leave out the dirt
I'm not trying to start a fight, I was just commenting that Walstad's
method isn't as carefree as it might seem because the definition of 'dirt'
