covering plants to flower early?

i read alot about determining sex n covering the plnat wit black bags b4 dark and taking them off every day out side? has ne one done that seriously pain in the butt wat i think but i wonder if i would work in june and july or so, i got fifteen sprouts and would like to start flowering some of them when they start to get big let me know what you would do

if its in your back yard or somewhere you can be everyday then go for it if you cant wait untill harvest season..

i know how that would be must be nice to have it near but its a quick quad ride then a quick trek but doin it early in the morning would be a bitch its jus i want to have sum bud early ya know

ya forsure man we all know how that is well its really u 2 you... you would probably be better off waiting because the plants will be bigger and buds will grow bigger under nater flowering..

shading plants during intense summer sun can produce awesome smoke budding under the hot,U.V. rich mid-summer sun should produce more THC than the weaker rays in the fall or so I've heard from folks in the know good luck

If ya covered a month before nature turns to 12x12 that may speed the process up. Its a pain in the ass everyday and consitant.
