DOn't use the sticks no matter what your growing buddy tells you.

The sticks will release nutes very single time you water and first of all that is WAY TOO MUCH ferting.

Secondly, when you over do them, flushingis next to impossible as they just keep on keepingon releasing more nutes.

Thirdly, MJ in a soil grow doesn't need a whole lot of nutes. It simply doesn;t need them asmuch as people think.

Trust me, you can grow nicee without having to worry about nutes so much.

Nutes for MJ need to be delivered in a very weak solution. The sticks do not allow you to control the solution and strength. They are desinged for house plants likes ferns, rubber plants and what nots.

GO get some fish emulsion or schultz cactus ferts from the Home Depot.

Again, as Zandor says the keep is to deliver what the plant needs at the proper time.

Those sticks take that control way from you because of the AUTOMATIC release everytime you water. Not just once a week.
