oh contrare mon frare
go to emery seeds and you will see 584 strains, all of them different. If you grow, you can clearly see major differences between strains. indicas tend to be bushy and give you a sedate high and sativas give tall lanky plants with an up cerebral high and growers have cross polinated the indicas and sativas to create a massive variety of plants. some you cant tell the difference but most you can.
just because grower A comes up with his own strain of blueberry, doesnt mean its not really blueberry. it's like apples ~ growers grow their own varietys that fit their needs and wants and over a period of time they repeatedly pick the best product for their environment...and over time, carefully selecting the best apples from the bunch that have the characteristics you want will yeild your very own strain of apples.
as for hydro i hate it because it uses chemical fertilizers (natural ones are too chunky for the hydro system) and those ferts can give you headaches, jaw problems, and cancer. ORGANIC ALL THE WAY!!!!!!!!!!
as for my favorite strains:
The Real McCoy - smoked this in amsterdam and it was spicy and sweet...the sweet and sour chicken of the cannabis world...it looked like it was brushed with gold dust.
silver haze ~ crazy strong and masterful psychadelic high
bubblegum ~ wonderful bubblegum flavor
white rhino ~ smooth with a great quazi bubblegum flavor and tremendous body stone
blueberry haze ~ blueberry x haze, nuff said.
SAGE ~ from the strictly conniseur file, this one has a unique taste...very fragrant.
