Wondering if I have everything in order...

Hey everyone, I am about to embark on my first journey as a grower. I have researched for about 2 months and the more I read the more I worry.
I was gifted with a VivoSun 4x4 tent and Oneo 600w LED light and decided to invest in the rest of the equipment. I have a 4in 200cfm exhaust fan, 4in 180cfm intake fan pulling from outdoors with a standard filter. Automatic ceramic heater, humidifier, two 6 inch fans with temp control settings, and a timer for the light. Made my medium with 60/40 Coco and Perlite.
For nutes I have Humboldts Secret A and B, CalMag with iron. I have readied 3 tiers of pots for seedling to final with the last being a 5 gal bucket with 1.5in of pea gravel on bottom and holes drilled for drainage.
I feel like I've gotten everything I should need for the grow.
My main concern at this point is that I have no vetted seeds. The seeds I have are from what I have smoked. I always save any I find in the stuff I really enjoy. I was told supposed strains on a few and those are Sour Diesel, Chernobyl, Blueberry Kush.
I've been playing with the setup and I have succeeded in holding the tent at values between 72°-76° and RH 40%-80%
I have researched my ass off to try and make sure this grow is completed with the best yield possible and I'm still very unsure. I plan on trying to get at least 2 plants to harvest, more if I can. I'll post with pics as I go.
Any comments or advice would be greatly appreciated. Will the light be good enough, the medium? Should I invest $ in a drip system? Etc.
Thanks in advance - J

 

More responses than I expected so quickly. Sorry for the tardiness on my part. I was at the end of a 12 night shift and was heading home.

I have looked at the seed cost vs the cost of feminizing my own plants and I believe that I will be initially buying some AAA Seeds as Regular rather than feminized and I will be feminizing my own strains after.
After all the reading I've done I'm really interested in the genetics and breeding aspects. I'm aspiring to come up with a Master Strain of my own. Seriously. It's like a form of earth magic or something. Amazing stuff.
I have never grown cannabis in Coco but I have over 34 species of succulents/Cacti that I maintain on my porches. I actually bought soil before realizing that it was dangerous to use time release fertilized soil. During the same research session I found out that the main ingredient in my house plants was also a great main substrate for cannabis, Coco Coir.
That's actually saved me about $80 in Medium costs because I already had a stock of Perlite and Coco. I have sphagnum moss, sand, and other substrates too but I do not have the experience yet to be able to make great judgments on Medium mixes.
Thanks for the welcome. I've been stressing with all the reading because I have no one in my "Circles" who grows anything but houseplants. Glad to find a forum where I can figure stuff out and share thoughts. Much appreciated

 

If you mean a timer for the light I got one of those too. Forgot it in my list. It was 4 bucks at Walmart but it's worked for my dry runs without issue.
Good advice though. Definitely a priority because I am not the type to listen to a timer for the plants schedule.
Also, I am already a recent subscriber to From Seed to Stoned. He's pretty good about keeping his videos interesting and gave me a couple of the ideas I plan on implementing.

 

The person I got the tent from says it's the perfect size for a 4 plant grow but thinking about that much attention needed for my first full grow is fuel for anxiety. I fully intend on getting there but I'll be taking baby steps for a while.
