i have 3 in netpots. and the only purpose of the pebbles is to stabilize the plant if im correct? and ive seen others on a different forum use the neoprene discs and just normal rocks to deal with this problem. and my plant has sprouted in the peat but is only about a cm high. time to move into the buckets? i plan on starting the nutes a week after putting the plants in the bucket and slowly moving up to more and more nutes for the plant to take in. does that sound good? and ill research the formula u speak of but right now i plan on using the lucas formula, which consists of all three as well.
