Newbie Questions


Hey all, I've built a Deep Water Culture system.  Also in the process of building a Aeroponics system.  My DWC I germinated the seeds in rockwool.  But I dont think I left them in it long enough for the roots to get established.  Learning curve. 

So, a few questions I have as a Newbie.

1st; Am I correct in letting the seeds germinate and establish a root system before I transfer them to the clay pebbles?

2nd;  I have a ph meter.  I cal it about every month to ensure it is correct.  I also bought a PPM meter of Ebay.  I check the PH and PPM daily.  Also I am using well water.  My PPM is always high.  I believe I need to switch to RO water.  This might help the PPM issue.

Am I on the right path?  I am growing everything outdoors for now.  I wanted to make sure that I can prove hydroponics before I buy expensive light.

Any contributions would be helpful.

Let the roots pop out the bottom of the rockwool and then put the plants into the hydroton.  Lettuce will then extend roots past the net pot in about 3 days.  I put my rockwool all the way to the bottom of the net pot then fill it with hydroton.  Works every time.  Do you mean your PH is always high?
