Oh I get it... and what nozzle is a good choice on the cheaper side?
Fogg-it nozzle!! The single most indispensable bonsai related item I have. I've lost it for a while before, tried the thumb and all sorts of other nozzles, they all made me swear.
Standing hot water in the hose becomes a cool mist at about 8". You can water a pile of perlite without washing it away. I even think its good for tree health. Chlorine evaporates from the vaporized spray and the dissolved 02 content of delivered water must be very high. Volume can be an issue with a large collection and high volume pots or boxes, that's the only drawback. I think mine are the 2 gallon/minute model, I just ordered the 4 gallon/minute, didn't know there was a choice until now. Pretty much indistructable too, this one pictured was lost in the garden for 5 years, dug up this summer and works like new.
Great for misting collected trees. Blasting off bugs, ie aphids, works great, get in close, gentle on the tree and leaves.
Cheap too, see the link, I haven't ordered from the company but the price looks right.
Try it out, let me know if you love it as much as I do!
Ah, can't paste the link, google growers solutions fogg-it nozzles
Not much opinion on cans here, something with good reach and nice spray
