seeds in the 2 liter bottles

[DC1]

Hi Ron I just built your 11 plant system I have 3 question 1. How do you set up the seeds in the 2 liter bottles which 2 books that I have bought on hydroponics have not answered the seeds I want to grow is pot

2. And for the pump do you need a timer or do you leave it on all the time

3. What is a good ready made nutrient to use I don't want to mix it for pot

Sorry for all the stupid questions but I am having a hard time finding the answers from the 2 books that I own on the subject

Thanks DC
