hey al hope you are feeling better.

i have darn near duplicated your set-up as per your ENTIRE 2 week harvest thread. wow what an awesome read!!! any hoo since there wasnt any info on the type of tubing until i read this thread i bought clear vinyl tubing and have developed a bit of a mold issue inside the tubing. all of wich could have been avoided if i had just cleaned the tub out every 2 weeks like you said to but of course i didnt and i pushed the boundaries and stretched it to 5-6 weeks b-4 it caught up with me. the plants are doing wonderful but the tub and inside tubing are icky. so i'll clean em today then i'll be good and clean em out on the 2 week schedule. do you think i'll be ok with the clear or is that a nono?
