The way one uses a brand new thin razor blade and how the cutting is scraped and carefully selected between nodes, cleaned up, etc... all this has a lot to do w/ if a cutting ends up rotting or not. the clonex gel has worked like a charm. i'm sure any powder is just fine. i never use any hormone when i use the aeroponic mist system which is def the preferred method. the low-tech translucent plastic bins (from anywhere) are awesome, cheap, portable and very effective once u get them down.
Is the Oasis product exactly like this floral foam... what the heck is floral foam made of really? toxicity? Porosity - Is it made to hold too much h2o?
i've used rockwool cubes in a dome w/ good passive air circ, moderate humidity. try throw-away plastic gloves and weak hydrogen peroxide to sanitize your dome (any clear plastic bin). florescent bulbs directly above, 20-24 hrs. heat mat, without baking, will increase your rooting to as fast as 1 week, w/ the easiest to root. i also like jiffy seven pucks and any coco product.
