Mary, Mary, Quite Contrary, How Does Your Garden Grow?

This is an update on my aquaponics garden, because I have received a number of requests for updates and pics.  I am not sure how many goldfish I have gone through, but there are 6 healthy ones in the tank now.  I lost a number of them early on because it just got too cold at night.  Now, the night temps are fine and they seem to be doing well.

My basil and cilantro seem to be thriving pretty well.  And the lettuces that I planted as seeds have begin to grow like crazy!  I can recognize the romaine and several different varieties in the gourmet mix.  They are about 1 1/2 inches tall now and growing very well.

I haven't had any problems with chlorine or nitrates/nitrites, but our water is SO hard that I have had to lower the pH.  I used a little white vinegar - don't know if that is really approved, but I know that it isn't harmful to people and NOW I know that it isn't harmful to fish:-)    I need to talk to the experts at the hydroponics store to see if they now whether it will harm the plants at all.  So far, seems just fine and it lowered the pH perfectly.  I figure now is the time to experiment:-)
