Not everyone is you or wants to do everything the same. Some people want to do things differently for no other reason but to lead their own path. That path may get me to the same place as you in the end or it may not but it will be mine. I sit on here and the internet and read, I would assume more than most, loads of information and opinions about what is right, wrong or just different.
I like to pull ideas from everywhere and the come up with my own design. It's simple really. Water flows through pipes, oxygen is added and nutes are feed to the roots. You can get there is a Porsche or you can get there in a yugo. I like to believe my grow setup is much like my car, a Kia Niro. The car does everything I need it to do even though it may not be as beautiful or as perfect as the Lamborghini.
If the only thing I do is use more water and nutes I'm ok with that. You really think 5 more gallons per container compared to last grow is the difference between a working system and failing?
