Build a second container with drip tubing so you can can double the reservoir size and you can fill both from second tote.

are you measuring ec/ph this year?

Have you tried using DWC for a pumpkin plant? I know it's late but I'm going to start one and learn for next year. Im afraid that the plant will drink to much water and I'll be left with hit nutrients using kratky due to the heat here in central Texas. Any input would be appreciated.
