Hi, its great to find this website & blog! I've had a few Aerogardens and just bought a Farm Plus.
I'm happy to know there is a solution to tomatoes not doing so well..... as soon as I get your book I will know what things I need to buy... PH meter, etc... and the concept of completely replacing water each time you feed it?? WOW, I have not tried that yet, but with 2 days left to "feed day", I will replace all the water! I am using distilled water (Arizona tap water is SO hard, its almost full of rocks!!)
In the meantime, if anyone sees this and has advice on growing Recao/Culantro, let me know. So far in the Aerogarden for 12 days, everything else sprouted but the teensy Recao/Culantro seeds that I planted in three new pods/w/fresh medium -- they not only did not sprout, there is a bit of grey mold growing in one of the pods. ADVICE WELCOME!!!
