Yes it's normal for the leaves to droop, especially with certain strains that have very soft stems, they about look fallen over for the first week.
It's also normal for clones to yellow out during their process. When they leaves start yellowing thats a good sign your cutting is about to root.
Leave about two fan leaves on the cutting. I like to clip the fan leaves across in half.
I use the rapid rooters, with CLONEX.
your doing great with the humidity dome. Get the flourescent lights as close as you can to the top of your dome without it burning the plastic. Leave your light on for 24 hours. Keep it misted inside your dome. Don't let it get soaking wet in there for it will cause mold. Just keep it misted, humid... put a thin layer of dirt along the bottom inside your dome, and mist the dirt. it helps hold humidity. Also, get a heating pad to put under your dome, and turn that on for an hour a couple times each day.
Your clones need to be at least 3 in. long. You need to lightly scrape the side of the stem at the bottom, about a 1/2" up. Scrape the side lightly to expose the inside fibers more, then sit it in your cloning gel. This helps the cloning gel soak into the cutting better, and produces more roots.
NOW, the real important part. The rapid rooters can be tricky...this is what i found works the best. Get the rapid rooters fairly wet the first time. not dripping wet, but to where if you squeeze it drops will come out. Then after dipping your clone into your rooting hormone, place it into we rapid rooter and take it to your dome, put the lid on and switch on your light and turn the heating pad on!
Make sure you keep it moist in there everyday, and keeping it humid in there every day. Lightly Spray the tops of your leaves to help feed them and wash out nitrogen
k.. the important part , part 2...Wait for the rapid rooters to become close to dry, this should take about 5 days if you are properly misting and keeping correct humidity in the dome. Once the rapid rooters are fairly close to dry, go ahead and get them wet again. Not as wet as the first time though.
Usually after you get it wet the 2nd time you should have your roots starts shooting out the side of the rapid rooter
I get clones rooted 8-10 days.
its a cool site to see, wait for the roots to develop before transplanting. Start with small mediums and work your way up when transplanting too. I use 12oz clear plastic cups with poked holes at the bottom so i can see the root system.
hope this helps. if you have any other questions to clear things up just ask!
