Hi Ron!
Its me again, Greg B. in Fort Lauderdale Fl. I asked you about the lava rocks, and you suggested
that " I sterilized because of the toxins that pure lava rock has. I would water every 20 minutes or so
for 5 minutes and maybe more often." How would I go about sterilizing them? They are growing
tomatoes just great but the ph has to be adjusted every day because it goes way up. I am adding
asprins to control it but I am afraid that it will do harm to the plants. Has lava rocks got the acid 'built
in it or something? anything I can do to get rid of it?

Thanks a bunch, your friend in Florida Greg B.
