good tips !!
when did u begin flowering nutes ? when u switch 12/ 12 ?
and i have 120X120cm grow tent ( it is homebox ) and 600w dual spectrum HPS .
do you think how many plants should i grow in that tent ? should i use 11L or 6,5 litre pots ?
i'll begin flowering nutes the 3rd week of bloom
i personally would use bigger pots than smaller.
as for how many plants you want to grow, thats entirely up to you,
if you go with 1 per square foot which would be 16 in a 4x4 area then you'll end up with around 2 ounces a plant
if you go with fewer plants but bigger then you will get the roughly the same yield but off less plants
the number of plants you grow doesn't mean a scrap, its all about area and lighting
whatever light you have it will only cover a certain area, a plants nature is to dominate the sunlight and not be dominated so a plant will take up pretty much whatever space you let it have if you only let it have a sq foot then it will grow upwards more than outwards and vice versa, which is why the yield is more reflective on light and area than number of plants
you could put 30 in there but your not going to get any extra yield
its better to go with less though imo because its less risk in case of getting busted and its far easier to care for 5 plants than 50
get your skills down first and learn to understand the plant and then you can start playing around and doing experiments
just gotta be nice and white
