Well here are a few pros and cons for each... maybe that will help
White Widow
Pros:
Insane smell, while growing, while curing, while smoking!!!
Kick ass high, makes you feel good (50/50 head and body)
Effective pain relief weed
Effective sleep aid
Long lasting high
Hardy plant to grow
Short flowering time
short cure time
Cons:
Hard to disquise the smell, while growing, while smoking
Comedown is rough, after you come down you are ready for bed
Not a big yeilder
Bubblicious
Pros:
Insane smell, while growing, while smoking (smells and tastes like grape bubble gum)
Very effective appitite stimulant
Nice high, not as good as white widows but comes in at second place for me (50/50 head body)
Hardly any come down
Nice long high
Some what of a hardy plant except mold
Short flowering time
short cure time
Cons:
Prone to mold while growing/curing (blah!!)
Appitite is so stimulated sometimes hurts you get so hungry. Could potentially be a
deal breaker in social events/gatherings.
Not a big yeilder but bigger than white widow
Super Skunk
Pros:
Huge yeilder!!
High flower to leaf ratio (makes trimming easy)
Smells and tastes great!
Long lasting high (60/40 head/body)
Cons:
High is skunk like which I dont like (personal preference i guess)
Hard to disquise if growing/smoking (pretty skunky)
Prone to mold while growing/curing
Some what of a hard come down
long cure time
Northern Lights
Pros:
Northern lights smell (got that piney/fruity smell....so nice)
Great taste (after cure, taste is fruity with hints of pine)
Great yeild
Great flower to leaf ratio
Awsome High (60/40 head/body)
Moderate length high
No come downs
easy to cure/dry
Cons:
Prone to problems (seems like an unstable strain from Nirvana) while growing
Flowering time is longer
I guess thats it for now. I will update it as I think of things. White widow from nirvana is just freaking amazing. I would have to say that their white widow is the defacto in all my grows. At least one of those plants will be in every one of my grows here on out. If you like that great "good feeling" buzz that makes you chill, kills pain and makes you sleep this is it. Straight up dank smell, and taste makes this a 9.5 out of 10 for me. It would be a 10 if the come down wasnt so rough.
