After yet another disappointing year on growbags ... looking at moving to either large pot growing or possibly the central watering idea ... small pots continuous watering. I tried 'BigDrippa' system - but not impressed with dripping nozzles. Mentioned here was Quadgrow ........ also seem mention of Autopot Welcome advice from users .. also anybody compared these 2 against each other ? - or any other recommended system. I want to try and purchase the right thing first time.
