All good info being given. And yes pH is important. I am lucky where I am from the tap water is on point as far as having correct pH level so I do not have to put a lot of thought there other than an occasional tap water and soil check to make sure everything is as should be. So for at least me it is a very easy and thoughtless process. I take cuttings as low as possible. I try for 3 or more nodes. But have success with 2. I dip them in clonex or even the first rooting hormone I bought when am out of clonex. Which is miracle grow rooting hormone powder. I was brand new and store only had that so got it not knowing any different. But none the less will use it when out of clonex and to be honest I notice no difference on time frames or anything between the two. What I have noticed is people seem to over complicate cloning quite a bit. I make sure my rapid rooter is moist but not drowning. I place dipped clone in rapid rooter and tear a piece off corner of plug to fill the hole so stem is snug and no light reaches inside. I place in double tray. One flat tray with nutrient mixed water then plug holder with holes for plugs to sit in. Covered by dome. I keep on top of seeding heat pad. Misting leaves two to three times a day as well as dome. And after a week I start to see roots. My first attempt took two weeks. I didn't have water in bottom of tray. Mind you the water isn't high enough to reach second tray with plugs. It only helps to keep humidity and at least I think causes clone to work harder cause it senses the water and knows it needs roots to get to it. Maybe smoking to much of my own shit. But did have huge difference in time between no water and having. Using this system has given me 99% success in a short time. I have also experimented and placed cutting in rapid rooter with no gel or powder rooting aide. And have had just as good success almost and a fair amount of time. So rapid rooter are by far better than rockwool
