topspins unmodded
5 mins on an unmodded is not enough place a dripper in a cup and try it
the flow rate unmodded is around 2ltr hour depending on how its rigged up
try 10 mins per cycle harry(if you got roots poking out the bottom) your runoff ec should be close to what your feeding
harry al have to do some digging for ya
it happened to me once and i started getting problems ph runoff was at 6.4 too
i had an article i think i posted it up on one of my old threads
sweet set up man they look good. on the subject of flooming.. ive read a lot about it and its apparently the superior method of oxygenating water just as dank demon said.. il post some old links if I find them. good luck buddy!
yeah plus you ph might change anyway. I wouldn't avoid aerating the rez too much because the water will just go stagnant. plus its good for the roots to have more o2 in the water
Okay SupaFunk.
I'm wondering what pump to go for. Too small and the surface wont ripple, too big and I'll have a fountain - then there's the falling level in the tank.
best do sum reading.
