That wouldn't be practical for me I take 45-50 clones at a time. That guy talkin about wringing the air bubbles out of his stem is something else! One thing I learned here that really increased my roots was to shave the skin off the bottom of the stem, after doing this I had greatly noticable lateral shoots.
one reason i pointed out this method was cuz its diff. than just clonin in a galss of water cuz it has a top..keeping humid air arond stem were roots start to grow.thanks for the replies+ cheers+++....moonnnsssszzz/
