I see a lot of peope struggling with clones.
I keep things as simple as I can and get faster results than some people get in thier aeros.
Take the cut, dip it in clone gel, put it in a pre soaked )at correct ph( root riot cube upside down that's already had 95% of its moisture squeezed out by hand so they feel very light to pick up. Put them all in the dome with no leaves touching each other. Give them a light misting and mist the inside of the dome lid pretty well but not enough so it runs. Put the lid on with both vents closed. After 2 days remove lid and replace again, crack one vent. 2 days later remove lid, replace and crack the other vent. 2 days later remove and replace lid and make sure both vents are fully open. If you dont see roots over the next 3 days using this method then it will not be down to the method used but down to the mother you took the cuts of. Some strains root easy, others do not.
Almost missed out my light!!
I place the dome on my bedroom floor so it's not directly in sunlight and I live in the UK we dont get much sun its always cold. Job done.
I've just rooted 9 using this method and I had roots in 7 days on 8 of them.
