If your new, forget autos, they are not all they are made out to be.
Autos are fussy and fiddly and unles you are a great grower with great equipment, getting good results can be difficult due to their limited life cycle.
If you are new to growing, you will learn a lot more and get better returns growing photoperiod fems hands down.
Taste and smell have more to do with growing techniques, drying and curing methods rather than purely beinng strain specific.
Potency/effect is strain specific, but most seed strains these days are more than potent enough..........don't be fooled by THC percentages, effect is a combination of many things, not just THC amounts.
Finding somethig you like is a journey of discovering hits and misses..........there is only one way to do it and that is to grow them.
Buy seeds from big, long time established breeders, they may cost a bit more, but you are paying for well stabilized genetics and a lot of R&D that went into making quality strains..... think Barneys Farm, Sweet Seeds, Mandala Seeds..........all their products will give you top class results.........20+ years in the industry is not a result of luck, it is the result of good breeding and good products.
Generally, cheap seeds = cheap results with unstable plants.
Like everything in life, you only get out what you put in!
There are no short cuts to growing good buds, time and effort will be rewarded, short cuts and skimping on inputs will lead to less than optimum results.
You will make a lot of mistakes, learn a huge amount and each harvest will be better than the last..........growing is a wonderful hobby.
I have grown 100s of strains over the last 40 odd years and never grow autos any more, only photoperiod fems, I like to be in control of my plants, not grow plants that do whatever they want!
