my advice?
read through the GROW FAQ
(big red letters. top left of page. cant miss it)
taking time to understand what different grow mediums bring to the table
(hydro...soil...soilless/coco, etc)
each different style has its own needs, and pro's and con's, so, one must know the differences.
for example...
when growing in water its better to have a pH in the 5.8-6.0 range. (sometimes, even a lil lower) While soil grows benefit more from a pH in the 6.3-6.5 range.
once you have a general idea on what style you want to do, and what special things that style of grow needs......
THEN pick a strain that youd be interested in growing.
id recommend tried and true strains, as opposed to the expensive flavors of the week like sour d and chemdog.
a classic NL for a first grow usually is enough to get people hooked on growing. is SO forgiving and yields well even with mistakes.
C99 is popular and very easy to grow, too.
GroDocs bubbledust and angeldust fit the bill, too.
sweet tooth and ultimate indica are heavy, easy grows, as well, but it all depends on what type of buzz your looking for.....
skip the big buds, and chronics of the world. all weight and no punch. some have cuts that are otherwise, but, thats after time and money selecting. and, tbh, the buzz really aint worth it, imo. i always hear new growers say they want to run chronic,
big bud, etc etc etc....
they see these huge pics of buds but have no idea how lame the smoke is.
so, research your STYLE of grow and research the STRAIN you want to grow.
in that order.
and ask questions along the way
