I up potted 10 plants yesterday to the flowering room,,,,,i took 2 clones from each plant (20 clones) 10 in rockwool ,,10 in jiffy plugs ,,want to see witch grows better,,,,im sick of ordering rockwool thru the mail,,,some times it takes a week to get here and when it shows up its not the ones ive ordered ,,,jiffy plugs are less the half the cost of rockwool and I can walk into any Walmart and get jiffy plugs,,,will post the results as they start to root....hoping the jiffy plugs are equal to the rockwool,,,,zig
