lol, how do country brother! not totally sure what ya mean by mtl? (qc?), but me a prairie dweller... he he he....
as for the pump, i got it at a locl hydro shop, says NGW on the box, asked him and he said he gets them outa ontario, sorry, not much more help there....
Now, as for the cloner success rate, the only time a plant died on me at all wuz after i tryed to keep my T5's within 8" of the plants in there first few days! you can stall them out by using to much fert in the cloner mix, lol, i did that by trying to use rooting agent in the mix... NO GOOD... lol, i found this Growzyme stuff that helps roots but it's not a stimulator, and you even gotta use it at a way weak mix....even stalled them with this before!.... best thing to use is just water, and if ya gonna use the air stone in the rez, get ready for a ph battle (less u use RO water)
