So im almost done with my first grow and this plant u cant smell it unless you are right beside it. but i just started some White widow and sour diesel and my question is will they smell very strong.

depends.
what was the first strain? how many plants of WW and SD? in what kinda location? with extractor?

chances are good for smell, im guessing the first might have been bag seed? the WW and SD are potent and if your going with a lot of them then your probably going to start noticing it. as well, if your growing out in the open then expect more smell, if you have it in a closet at least some of it wont permeate the door.

why not just make a carbon filter? it takes all of $10 and works

heres a few links on this website for carbon filter techniques, though this was just what i could find off a single search. if i were you ide scroll up to the top and pull down the search bar and just type in different combinations of the words "DIY" "carbon" and "filter". youll have to sift through some bull shit but youll find great stuff, pictured ones are a lot more helpful. This one is my personal favorite and what ill use most likely:

As for your plant numbers, that isnt to bad, you can also search and find out what others have said about the strains potency. They are more potent strains but you shouldnt be extreamly overpowering with only 3.

good luck man

ohh and i guess i never really asked but should have, are you growing in a box or out in the open? cause if your out in the open then youll probably think my favorite is shitty because i grow in a box that only needs a small one. either way, search and sift, youll find a lot more than asking people to help you cause they said it once and most of them are to lazy to explain it in detail again.
