Questions about autoflower grow setup

Hey guys, thanks for the answers! I want to start a grow with a 4x4 tent. Im thinking of using 5 gallon fabric pots. and my grow light is
Spider Farmer® Upgraded SE5000 480W Full Spectrum LED Grow Light
Im thinking im gona do 18/6 hr lights, and im gonna try to do Sea of Green and LST on the plant. and the strain i picked was https://2fast4buds.com/seeds/wedding-cheesecake-auto#description

my goal is to get minimum 100G of each plant.
My question is do you guys think this setup will be valid? And if so, have any ideas what type of nutrients, grow medium, boosters and other methods i can best use?
I think Coco is good?
Im trying to start slow on my first grow and want to do it as easy as possible to ensure i atleast get some yield from the first grow.
So i dont want to go crazy with the feeding and nutrients and training just yet. Im thinking of growing 6 of these in the 4x4. I basically want to try to make the process as easy as i can in the beginnning while going for that 100g mark.

I'm on my second indoor grow with autos. I found out right off the bat from people here that trying to use a scrog method on Autos is a waste of time. Even for practice. The net did more harm than good in my case. I removed the net after about two weeks and had to trim and tie down most of the plants to get better light and airflow. I topped an auto by accident and that plant has 16 tops. Just sayin.
Keeping it easy? it's not, but you don't have to go crazy with the details. A good soil balance rich in nutrients, has been working for me for autos. Just watering so far. Good luck.
One thing that helped the most this time is paying VERY close attention to environmental conditions. I did this by adding monitors, extra fans, a dehumidifier. I also am leaving the tents mostly open to improve circulation. Autos don't care about the light cycle.
I need more practice but I'm learning with each plant. I tossed one in the trash that I think was never going to flower. I've got two other weird ones. The rest are looking great.

Sounds like you've done your research....that's good.
First grow, my best advice it to keep it basic and as simple as possible.
Go soil, one or two plants, till you get the hang of it, as above don't bother with LST etc., if the plant gets too tall cut the top off.

Have fun

Autos do great in a good soil with mostly just watering. They tend to be hardy plants.

Your setup sounds great, that's a nice light for that space.

Scrog works for autos. I had good success just bending the plants over from seedling, and scrogging all the side branches it puts out. They also work well as a single cola (not topped) plant, and tend to grow like x-mas trees. Genetics do play a part in this, but that was my experience.

I wouldn't suggest topping. Most likely it's genetic dependent whether they go stunted or not from topping. I've tried, and ended up with stunted plants that were tiny, no where near 100g.

Your goal of 100g is a good challenge! I average ~30g per plant (not autos though) using 1 gallon fabric pots. It's definitely doable in 5 gallons.

I have heard to make sure the goals that you have set are "reasonable and obtainable". Your goal is achievable but growing six five gallon plants in a 4 x 4 is going to be a hell of a learning experience for the first time. Even with autos its going to get crowded in there quick. I would maybe drop down to three plants in 3 gallon pots for autos. I personally like coco to grow in because it is forgiving and easy for me. You will have room to figure out how to set up your tent properly to your liking and also learn how to get everything dialed in like nutrients and environment like the other guy said.

My biggest mistake first grow was too many plants to deal with all at once. Nine autos in a 5x5 became crowded real fast. This time around I have five nice looking plants with lots of room to breathe and get light. Less maintenance and its looking like I may get a better yield from five plants than I did with nine. I'm waiting very patiently for harvest time. I know I chopped too early the first time. At least this time I still have smoke from the first run while I wait. "The waiting is the hardest part."
