My belief is that is you are going to have 8 plants in a 4x4 It will naturally be a SOG that you are going to have to be on top of it as it is going to fill out awfully quick.
No worries though, just have to watch veg growth so it doesn’t get to crazy. I typically tie my plants down very early to form the plants shape. I tie them down as early as 5th node. When the plants have the shape I am looking for I grow them vertically from that point forward. (Old pic but you get the point)
Air Movement/Flow/Circulation is going to be your best friend.
You can’t tell from the pic but I have Fans Moving Air at pot level, Canopy level and above my lights.
Yes! I would experiment with all of this. Best way to learn IMHO is by doing it and experiencing the results 1st hand.
Take a ton of pictures of your grows as well as a bunch of notes . As you grow you will learn and what a better way to learn than going back through a ton of pictures/notes of your grows and seeing things. You will see things your remember and a few things you may had missed…
Yes! I would not worry to much about pollinating as this is your 1st run with the genetics. I would take clones and after you grow is cured and you have time to smoke a bit of your labor you will have a better idea of what you want to concentrate on.
You may want to run a search on the OG to assist you with organics.
I would recommend a few for you.
Oh ya!
I am a soil gardener and absolutely love what I have been able to do in a Sub Irrigation Planter (SIP) using Natural Inputs.
There are a bunch of other posts but the ones above will lead you to many more OGers running Natural inputs.
Can’t wait to see how your grow progresses…
