Need some help

The easy most fool proof beginners grow is soil. Plain Dirt.
Most use FFOF ( Fox Farms Ocean Forest) I use it myself for the initial stages of veg.
Square pots give better root branching in my experience.
Some 3x3x3 inch squares and some 5x5x7s

Start seeds in a half filled cup so when the seedlings stretch you can just add more soil rather then the stick and string routine to try and support them.

Your in the prime spot for clones so run down some dark heart stuff.

go and read on growweedeasy.com

thats where most people start. Its a LOT of reading before you will have an idea which way you want to go and what you will need. since you are new to this I would recommend growing with soil and either bottled nutirents or just try to build an organic soil if that is your preference and just try to finish a first grow

 

If I were starting off new today, and wanted the best combination of simplicity and effectiveness, I'd grow autoflowers in Autopots.
As BNW points out, dirt is easiest.
Autpots can accept either dirt, dirt mixed with perlite, or the most popular, which is perlite and coco coir.
But dirt also has its living creatures problems.

Personally I greatly prefer hydro, but it can add an extra layer of complexity.
In general, people who are comfortable with measuring devices will like hydro.
A good starter hydro system is a single, 1-plant bucket with an air stone and air pump.
A good LED, pH pen, ppm pen are also needed.

When you decide on more particulars, much advice is available here.

 

yea its quite the learning curve, but well worth the ride in the end when you harvest something nice. Lots of fun, too. One of my favorite hobbies now.
