I’m not sure on those buckets cuz they have a very small reservoir in them! An earthbox junior holds 1/2cu ft of soil and has a 1gal reservoir and the full size holds 1cuft and has a 3gal! This gives them a lot of airspace in between the water line and the soil deck for the roots to get plenty of oxygen! I’ve never used a bucket like that with a small reservoir so may need to let that go empty and then wait a day before refilling so the roots can get plenty of oxygen! Also hydroguard is your friend just to be safe! Cheap and only need 2ml a gallon!
