Thanks GPS -
I appreciate the info. What you say makes perfect sense. I have already started to notice a bit of dry salt stains on the very tops of the pellets in my system. How often do you flush your systems. Is there a rule of thumb you use?
I have been pretty impressed with my lettuce's progress so far. I transferred seven seedlings into the system on Tuesday and Wednesday and already they appear to be growing very well with the first real leaves starting to appear.
BTW - what
nutrients do you use. I noticed that I am supposed to be adding a number of other products with the Cocos A & B. I assume that there are other, less costly/demanding products.
Thanks
