[Resolved] High-Frequency Fertigation and Autopots

    Hey Josh!

    I’m using a few autopots with a high-frequency fertigation schedule and I’m curious if my plants being in a tray their whole lives without drainage will cause salt build up over time. I only give them water mixed with solution at a relatively low EC. If I manage nutrient feeding correctly will there be any need to flush the system occasionally?

    Hi …… the salt build up occurs in the top 1-2cm of the pot so there is no effective salt build up that will affect the roots…… you should also never pour solution into the pot or you will wash the salts into the root zone…. this should only be carried out in emergencies if you have a lock out issue….

    Regards

    Hi. Same question I suppose.
    Have just purchased you Autopot 24

    My first ever grow so as green as my plants hope to be 😉

    Haven’t sorted nutrition yet but every where I read is the importance regularly measuring EC, keeping it even with little fluctuation and to measure the run off.
    Can you suggest a good routine/system of how to do this.

    Many thanks in advance and no doubt will have loads more questions 🙏

    Hi You simply set the correct Ec and pH in the reservoir there is nothing else to do once this is carried out.

    Hello Josh. Similar question. I am currently growing 8 plants, 4 regular and 4 XL. 60%coco and 40% perlite mix (coco prebuffered and regular 5ml/gal of calmag on each fgertigation). On week 8 of veg I started noticing, the plant leaves getting droopy and several nutrient issues like phosphorus/nitrogen deficiency. Ive ruled out other issues and concluded that it is most likely due to nutrient lockout. So I started flushing with flora clean for all 8 plants and continued with regular nutrient dosage by top feed hand watering. In 2 days I’ve noticed significant improvement and rapid growth rate. Right now I am hesitant to hook them back on the Autopot system fearing the lockout issue would recur. I would like to avoid that if possible since Ive just entered week 1 flowering.

    The issue is, the main reason I got the Autopot system is to allow me the freedom of not watering them everyday. Can I hook them back to Autopot, observe for a week or so, then if the response is still poor, maybe I have to go back to manual hand watering? Or do you have any other suggestions. Thanks in advance.
