I plan on using the lucas formula of micro and bloom GH nutrients and was just wondering how much i should buy for 1 grow using 2 or 3 5 gallon Bubble Buckets?
I paid $40 for a gal of micro and bloom, together. The quarts were like 30-something together... if prices are close at ur local shop there's no beatin it. It'll last a long time! But a quart of each would do ya depending...
One quart of each would probably be enough, depending on how long you vegged and flowered, and you would have about half of the micro left over at the end.
