Auto Jack Hempy

Watering twice a week roughly 4 litres with about 20% run off, the run now tells me the roots are in the res as the EC reading is lower than the feed, it has also taught me to wait a few hours after mixing the feed to recheck the PH as the run off PH was higher than the feed! 3 years of reading all forums is paying off, so a big thank you to all the growers who have shared the the love!
