DWC is the ONLY hydro I do now, I did the drip thing for a while, but was tired of having all the build up on the rings and having to clean them out almost bi-daily. I want to do a single nozzle drip system for clones and mothers in the future.
I've been doing DWC hydro for quite a few years now, and I am going to be starting my new set of seeds soon. I've also just got some seeds coming off of my latest harvest (purposefully seeded a cross-strain) it will be exciting to see if the results come out well!

1. do i have to recirculate the water? or can i just change it out once a week or 2?
You can do either, however, your best bet is to check PPM levels to determine when to flush the system and add new nutrients. The pain in the booty about this is that when your roots get long, it's hard to keep them under control when trying to change water. Make sure you have a back up bucket handy to place roots into when doing the swap. Use PH approved water in this backup bucket so that the slightest breeze of air doesn't dry the roots and shock them.
2. when i put my clones in the basket, should i feed the roots thru the holes or handwater till their sticking out?
Do NOT feed the roots through, it's much harder than you think. This will be taken care of when you add teh water to the bucket. You will actually fill the bucket with water until it's approx. 1" down from the root ball/area. This will ensure they grow towards the water, and the hydroton balls I use, actually absorb moisture upwards so the plant maintains it's proper moisture levels. It's like a wicking system.
I personally use rubbermaids with netpots and I usually do four plants to a rubbermaid for smaller grows, and 3-5 gallon buckets for larger grows. Mother plants can stay in a single bucket or in soil.
3. should the basket be in the water or just above it since supplying nutes to only the feeder roots?
baskets are in the water, 1" from the root zone of your plant. As the roots grow, you will keep lowering the water level as needed until you're at the bottom of the 2-3 inches of the net pot. At this point, the roots are already growing strong and sustaining life with roots submerged in water.
4. when swapping out the water, do i have to keep 50% in there or can i totally change it? example: going from veggie to flower nutes.
You can change out the whole system if you want, but this is harder to do than you think by leaving nutes in there. With DWC, you can change every couple of weeks if your ppms are correct and you are not building up a lot of salt deposits. when going from veg to flower I usually flush the system. If I need to top off, I add just ph'd water only.
5. once the roots get long, should they be bagged up in a net bag or just let them go wild in the bucket?
They go wild in the bucket. Do NOT touch the roots if possible, let them be. They're growing in to the water for a reason!! It's HYDRO - plants growing in water.
EDIT: ANOTHER TIP.....
DO NOT use LARGE bubble airstones or open hoses to produce air bubbles in the water. Make sure you use an airstone that puts out a very fine bubble pattern. I generally use a large air pump and several bubble curtain air stones. The smaller the bubbles the more of them, and this produces more o2 in the water. The larger the bubble the quicker it rises to the surface and allows more air to escape the top of the water instead of dispersing IN the water. O2 is super important in DWC.
