you can use the ice water method through the silk screen i 'spose...i can't see how it would be any diff from strain thru the bags other than you'll only have one screen (but i have never used silk screen either) you might need something a bit bigger too for straining out most of the green...maybe panty hose? just guessing...but seems like you would need at least one more stage to clear out more garbage...good luck

if you know of other growers in your area maybe you could all pitch in and buy a set of the bags.
