I've found that taking cuts about 10 days into flower seems to root the fastest. As in ready to be put into dirt in about 5-7 days. I used to use the brown cubes, rooting compound, and a cloning solution. Had a very good success rate. Since, a friend has given me his ezcloner to use and just use...
I worked with a guy that got a check from the power company each month instead of a bill. I intend on having a couple installed in the next couple years.
I use a 4" fan/filter combo in my veg area which is open in my work room and a 6" fan/filter in my flower tent which vents out the chimney. I don't smell anything but my girl says she gets a faint whiff when she walks in the door near the stairs but nowhere else.
1000w might be a little too much light for clones. I'm only on my third grow but I've had excellent luck with veg'ing under a t5 and not using any nutes until I noticed a deficiency and only watering when the pots get light. I grow in roots organic original and 707.
When lst'ing my kush plant I split the stalk right down the middle. I used a little duct tape to hold it together for about a week and it was good to go. I'm chopping it down today actually.
A dehu will work much better. But if money is a issue there are other alternatives like damp rid. If you get a dehu make sure it is big enough for the size of your room.
A friend of mine is a big smoker and will get a seed from tint to time in a bud. He for the most part only messes with high quality stuff so I welcome the seeds he gets. I've got a flowering plant from one of them right now actually.
