Holy roots. Couple questions for ya if you don't mind your much better then I am.
1. You mean you don't ever spray your plants? Do you mean You just spray the dome of just keep cube moist watering under tray?
I hit them every few days maybe to keep moist. The leaves take in humidity. They dont really absorb water if you spray it. Pores are to small to suck in water. Also cube is wet and they wick up the water. The leaves dont do much yet except die and feed energy.
2.When did you start giving the nutes/what type do you give(kelp,cal mag or just reg veg) and when did roots first show?
At about 10 - 14 days when roots exited cube. Just a mild 1/4-half strength nute to start.
I use CES and their mixing chart. There stuff is mild its fool proof. I buy 2.5 gal jugs from ebay or amazon.

3. Why do you leave them in there so long after rooting and what do you transplant into? I've heard about root rot, mildew or just tangling from leaving them in there but I'm assuming you have a reason for it and do you use a perlite bottom?
I have the root riot cubes only in the 2" baskets. No need for perlite. Look close at the pick thats it. I cut bottoms out and put 2 rubber bands from top to bottom to keep cube from falling out bottom.
Next at home depot I buy the black 27gal containers with yellow lids. Those are cheap $8 bucks. Top has diamond shapes. So i put 23 2" holes in the lid in the diamond shapes. I have a danner mag drive pump. Kinda over kill. But it has a 3/4" female thread fitting. I 90deg up from that into a 1/2" "H" bar I built with 1/2" pvc connected w/ 1/2"-3/4" adapter and drill micro sprayers in it. Prolly 30 sprayers. The red ones, a 50 bag is a few bucks.
To keep container from leaking i run the black rubber window door seal around the top of rim the lid snaps on tight. I can get you a pic if you want. FYI. It can drip. I have mine in a garden tub. Or put in kiddie pool and use pump to drain excess water into a bucket. How to control water temps when pump gets hot you ask? Easy fill the tub its in. It cools it right off and stabilizes to room temp.
4. I've always loved the monster cropping and gonna take some off my buddy's in a few weeks once he switches them what do you have for a success rate?
Those type of clones are hit n miss. So 50-90%. I fill 22 clone sites. The 23rd site has my power cord and sensor wiring in it. Etc. my rule is take 22 and i need 8 of the best looking clones. Toss the rest or give to buddy.
5. And do you prep your mother's with anything the week of or just use the flowering nutes since you already are?
No, just cut em. Week 1 or Week 2 bloom is best. But they can be taken at anytime. Cut off all leaves but tops. Leave The Bud On It. All that stuff dies and crazy colas shoot everywhere. Do Not Crop These. No need to they go nuts.
6. Last question do you use hps, flouros, cfls? And do you use 18/6? I've heard strong opinions on 18 and 24 hour
