I never really grow the same way, every grow is different. I tend to change it up more than most, although I do have my own style about it. I am always blowing money on things I really shouldn't need to, but then again it is more of a hobby in my eyes. Actually I spend more time trying to figure out how to have small scale luxury grow equipment, by building it all DIY from parts I scrounge up.
It's fun to grow multiple style's (aero/hydro/soil-less/soil) sometimes all at once, and keeps my over active mind busy. I like the challenge and the new skills I learn all the time. And I design equipment/systems that no one has seen before. A lot of the stuff I come up with I could probably patent, so I try not to show it all off too much, because someone else will. Mostly I like to give new idea's to the community though.
Growing legally in my state is kinda important to me, so growing monster plants now while keeping to my limit (without registering) eases the mind. My ex likes to send welfare checks, even though the cops are tired of her BS, and always leave empty handed.. and probably will never show up again at this point lol. I swear they red flag/inform the DEA anyway and helicopters buzz over my place still, because she said I have some large operation that doesn't and won't ever exist.
I've gone from 100's of different bottles of nutes\supps, being mostly free\samples from my good buddy at the grow store, to simply using Jack's hydro because he moved away and I have to spend money now. 1 time purchase of the 25lb bags, both cal-nit and 5-12-26, should last me into the next decade
I also got into raising chickens this last year, and building custom fully automated mobile coops on wheels (that even have NFT hydro lettuce growing systems on the roof), so I been kinda busy with that too. Backyard chicken's are taking over the country like crazy. Same with Tiny Houses on wheels. So i'm designing coops crossed with greenhouses, where you can get your eggs/meat/and veggies all in one. Possibly even brew the chicken shit into tea to grow the lettuce with.
I been growing for awhile, but always something new to try.
