I read some messages in here a week or two ago where some guy was
advertising his downloadable book. www.orchidstobragabout..com

I read the comments about his site and, since it was only $20, I bought his
book.

I have to say, like several people have on this site, you REALLY DO have to
give this guy credit. He's done a great job with it.

After I read the book, I still had a question about pH. I sent him an email
and got a detailed and quite helpful response in less than a day.

I give the book a green thumbs up! (in case anyone is interested)
