Hi If this is your first ever grow then you may make the same mistake 99% of beginners make, After going to all the effort to get those little precious beans from our good friends around the globe or from some stanky ass bagseed. Whatever the case may be this seems to be the most commen mistake or problems, and ofcourse the grower is never to blame (MY ASS). So some people may disagree but results speak for themselves. Deciding which medium to raise your beans in seems to be like the million doller question to some people, If so swing me the Johnny Cash. I would start them in a nice quality seed raising mix, use whatever pot/container you like as long as its not clear and has a bit of depth to it. Personally I use Seed Raising mix (Searls) with a sprinkle of worm castings mixed through for all my seed grows, hydro or soil. Though to be honest I havent planted beans in ages, As clones are obviosly your goal, And then a Mum or three will be in your near future. Had my mum's now for Donkey's. Wouldn't trade em for the world. As for your lighting I would piss those cfl's off straight away, and put them under the 400w. Start at a meter and work your way down over the days till they are happy, you don't want your plant reaching for light, but you dont want it too close either. Also in ny opinion the whole EC, PH issue is alot of people downfalls too. People are always adjusting then readjusting all the ph and ec levels till they wouldnt have a clue where there at so the have to flush and then generely do it all over again. As long as you follow the directions on of the nutriant bottles and flush with plain water once a week/fornight you'll be sweet Just keep it all as simple as possible, the plant will tell you what it wants not a pen. Just my 2 cents.
