i love the thread i just read the whole thing at one sitting wow that was alot.nice im a noob at this to but i have been reading everything i could find on this for the last 3 months.so i know a good bit more than i did to start.i read about all the diffrent type of setups my set up is dwc. i set up mine in 30 gal rubbermaid tubs fill 20 gal each i setup 4 with 8 plant sites each.i made a pvc spray bar with 14 360*sprayers each. i have it to where the water is right under the spray bar. and sprays all over the bottem of the 5inch net pots. then in the bottem i have the dual air hog stones so it's a 2 in one but from the bottom.

i was having a lil trouble with a lil alge. im guessing that was alge. a thin slick film so i was guessing the light was getting through the clay balls around the edges. so i went out today and bought sum emergency blankets. a buck each instead of using my good mylar. and i laid it over the whole top 3 layer thick and cut holes at each plant site and put the baskets back in for a nice tight light proof fit.i know i should have done something b4 all that but i didn't see any light getting through so thats done.i have my seedlings under 2 of those curling type lights the bigger ones not the lil ones i just bought 1 of those ceramic pull chain lights and wired it to a replacement ext cord and put a 2 way in then the lights my stuff is sprouting in about 3 days but i don't know when i should put into the dwc i have thick white fuzzy roots starting to poke out but they still look to lil to put in yet any thoughts on this? and 1 other ? i read that u (topped)ur plants how is that done? just cut off the top at sum point? i have well water it is 25 or 250 ppm by itself i guess ro/is the only way around this? or is it that big a deal to mess with? keep up the good work
