they have been in the buckets for 6 to 8 weeks with the same miracle grow soil that is supposed to last up to 6 months,they did grow faster and bigger than i thought.i dont see any roots coming out of the drain holes,is there another way to check? the buckets are 2 and half or 3 gallon buckets.should i try a 5 gallon bucket or put them in the ground?why are the other 2 so healthy in the same buckets? i will get the tester also.thanks a bunch.
