Alright for the matter of indoor VS outdoor, lets face it they both have advantages and disadvantages, sure you cant control when the sun gives your plants light but the intensity of the light is much greater then any light you can buy, aswell stress from the elements outside is beneficial for the plant as what doesn't kill it only makes it stronger. wind is what makes the stems strengthen and become more sturdy forthat you can grow big buds without the plant fallen over, and the rain in small amounts cleans the leafs, makes hte plant produce more resin on the leaf for a repelent and of coarse the plant will take in small amounts of moisture through the leafs.. basically if you got the climate for outdoor growing and you know what your doing, and you use the right strains you can defently grow grade a stuff outside and yeild much more, just remember location location location, i live in BC canada and i have grown VERY good ganga outside, infact i had a friend who grew the same strain indoors with HPS and i grew it outside, we used same nutrients, and the conclusion was that i got a bigger crop and my crop seemed to turn out much more potent. EXTREMELY dense buds, people knock outdoor all the time because they get this weird idea its all swaggy but its not true, it can be very much Superior, and dont froget half the process of getting really potent buds is the drying/curring process if you dont dry and cure them properly you wont get that awesome tasting no burn in the lung weed we all love.
Here's a picture of one of my colas from last year, fully cured, this stuff would knock you on your ass and make you speak in toungs, the strain is double O7
and its about as hard as a brick of hash i kid you not.
OUTDOOR RULES!
