You need to find out where your trichomes are at.....unless you just a are going to run it for a few days and then harvest regardless. You can run ph'd water through the system at the end for up to two weeks (and I have before) while you wait for the END....or just decide you are going to harvest next Friday or whatever and do it.

Watch the ph carefully during this time......it will jump around alot due to no ph buffers in the water.

Oh....and I probably wouldn't start adding a drip system or "helping" speed things up in any way as those things usually fall pretty flat. You don"t want to drown your roots either. You've gotten this far very well.....don't lose it at the end..
