I have 3 tents and will get a 4th.
Currently I am running 2 tents that are 5 square footers by 5 feet and i have a 4 x 4 and lights for them and the 2 x 4 i want.
10 bucks a gram and i bought it. Sparky ass weed. Shit i can grow wrong and not do it at the end too but i learned from that and mine is better.
So i say 1 plant per tent.
The light hoard at this time
232 watt samsung strip light (true northern lighting) in 4k
200 watt Timber 2VL in 3.5K (latest generation Vero cobs)
315 CMH with Phillips 3100 and 4200 bulbs
135 watt samsung quantum board in 4k
I can say nothing bad about any of the lights. They are all rock stars and i recommend getting any of them over a vipar or mars or blurple anything. You will not regret it.
And a door-stopping Mars Reflector 48. I would veg with it but that quantum 135 is ridiculously good and it is adjustable from seedling to full veg
Tech has made it great for the hobbyist
I have been investing over time. My wife needed the meds and then after I needed the meds and now i just love cannabis for pain and for general state of mind. I love multiple tents so you can grow 4 different strains and have a 16 week landrace in one and not care because you have an 8 week hybrid in #2 and #3 has critcal mass and #4 is a gangbuster....
Currently running king tut GG4 and critical mass. GG4 I have never tried and the others i love.
Total draw of power is 450 watts (killowatt tested with fans etc). Not too shabby.
I think growing at home is a hobby and I wish to be an elite hobbyist. I will let you know when I get there.
