Old fart who’s been smoking since 1979. Started growing indoors early 90’s for a few years under high pressure sodium lights. Restarted growing on my patio spring of 2019 when it became legal in Canada fall of 2018.
Now have a 4x4 tent using 4 autopots with air bases and air domes. A good 460 watt light, 4in Infinity AC fan with charcoal filter. A few fans and a little heater to keep the temp up in the winter. A good digital timer for the lights that has me trying a 6/2 x 3 schedule for veg.
I’m a lazy grower, so I use ProMix as a medium, Advanced Nutrients as nutes, that way I don’t have to test and adjust the water, just mix and dump! And now a small 4x4 area in my cellar, 4’8" high with my old 260w COB light. Amazon boxes for walls with Tyvek white paper as a reflector. Great to start clones and early veg for 20 or so plants!

Spudgunner? Ya! Three foot firing chamber with an 8foot ABS barrel…ever see a potato go 200mph? I’ve shot golf balls over half a mile! So Ya! Altho I no longer have my cannons, I still have (some) of the memories!
