Grow Mediums drain and replenish

[oldcoot]

How long do you guys go before doing a d&r on your dwc ?
I always did it weekly but lately been doing it every two weeks.
I do add more nutes weekly though.
How long is to long to go
Thanks in advance.

I go a week to 10 days. Until the ph goes unstable.

Remember that they use only what they need. So you ppm can go threw the roof by adding nutrient to your soup.
What are you running?

 

[oldcoot]

Yep i know. I check my ppm's and only add enough to bring it back up after about a week.
Gonna try every two weeks with this grow.
I just run a simple 2part gen. Hydro solution a and b.
Its in a 7 gallon tub dwc with drip too.
