How many Northern Light (feminised) plants in a 4x2 tent?

I usually do two in my little 2x4 but I like to grow them out nice and tall....you should be okay with three as long as you control the canopies and have enough PAR output.

Well if u look at my 1m2 tent, think I've 22 plants there. Some are 1.2 months in some are 7 days old. Starting all from the start. Id look into picking 1 good pheno.. And clone it. And do a scrog. This will give u the highest chance of reaching biggest yield if tats wat u want. Which I take it is. A good female plant, needs at least 60cm2. So if u do a scrog. You can put in 1 massive long pot. After 3-5wks. Pick ur best pheno. (Things 2 look for) how quick she stretchs, leaf, foliage amount. How easy to LST and so on. Also. With scrogs, hybrids 50/50 Sativa/Indica. Or 30/70. You can so pure saliva, you would just start at 1 end and Flming and weave the stems down your net. And when u flip all shoots will start to grow upwards all at the same height. There's a few ways 2 approach a scrog..feel free 2 mes me or anyone who has done and understands their process.

Really all depends on how long you plan to veg. NL is a smaller strain that typically doesn't have a lot of stretch. Should be ok.

the amount of plant may vary a lot depending your growing methods. 3 in a 2x4 is perfectly fine, i m growing 8 plants in sog in a 2x3 as comparison.

I run now same tent for 4th grow, 3 is max in my opinion. Have fun !
