Hold on there geekmike, I didnt ask the question because I knew the answer. I read from page 01 to page 08, and will continue to read all 272 pages. I was a investor and owner of a very successful nursery from early 80s to mid 2000s; my experience has always proved me, if you don't ask, you dont know.
So for that being said I wanted to ask the questions I may already know, to only build a stronger foundation. Weak foundation will only result in bad results because I missed a step or two. I'm the type of guy who wants to know the why and how, not just the how.
I ask these questions to better educate my self. I notice most of you guys are soil growers, I am a hydro grower; not much info was posted for hydro set ups, but just to know I'd not be a leech and get all the info and never come back to give my feedback and help other growers that might have questions for hydro set ups. I'm a sponge budda, I soak up all the advice & input and I put it to good use.
I asked what a node was, even if I knew the answer I still asked it. I asked how do I top, when do I top, and where do I top. How do I create 2 nodes, 4 nodes, 6 nodes, etc.
Can we use pictures to demonstrate this. (Please do not tell me to grow plants, and learn from your mistakes) I will first have a clear understanding, then have a strong forefront of the fundamentals so when I do grow, I can understand what I am doing and not be a mess when doing it. I want to understand the grow process rather taking a bunch of sticky balls and tossing them at the wall to see what sticks. I rather be more organized and prepared.
