• How much grow dots are used in a 4 gallon bucket with a auto flower indoor grow with pro mix medium and is that all thats need till harvest? Ive used the grow peacful buckets 16 so far and they are spot on just water except one had a cal mag deficiency a week before harvest.

    • It was recommended 75g for 3 gal , so figure safe around there and you can always add in for deficiency. I personally run on the lighter side so I can add in my own boosters.

      • 4 gal is the same size I use. What’s in your pro mix medium? I grow in straight coco coir, also in buckets. For coco coir with nothing else, I added 5 of the 75 gram bags, so 375 grams in total into 24 gallons of coco. That put me at 62.5 grams of Grow Dots per 4 gallon bucket, of which I currently have 6.

        Again though, I don’t know anything…

        • With unknown seeds, go with estimated flowering time to get an idea of how much it’ll need. Longer flower time I’d go with 100 grams in 4 gallon. If flowering time is short, then I’d go with about 80 grams in a 4 gallon.
