Agreed. Research is the biggest mistake I see with new growers.
Not that I'm any pro either, but that rectangle thing in your hand holds all the magic needed. Hell...that's all I've been doing....researching better strains for my location and environment, for growing outdoors, in my type of medium...Amended earth, and how I can improve it for what I'm growing .
To the OP...I understand, I went minimal last grow, too. I had less than $100 in all, for last years grow, and that included the gas in the truck and boat, when collecting fish to feed the plants.
I tend to shop at local greenhouse stores over big name stores. Folks there can help point u in the right direction for what your growing. Usually for a cheaper price, too. Even if it's a little more, the guidance/help is worth the cost.
Guys here may say things u don't like, but we all have your best interest. Ya just need to pick how you want to grow in, (medium) and how. ( Indoor/Outdoor). Pots or in ground/ raised bed, organic or synthetic nutes or hybrid there of
See...it's not complicated

It's a weed...have fun with it, it's quite resilient. learn from mistakes, that's how we better ourselves , and learn from each other.
