most definately a no

Im gonna say that humidity in itself does not determine sex, no. But for what its worth one of the breeders (i forget which one but i think it mighta been "greenhouse") has stated that they belive a combination of factors including humidity does.
Thier belief is that higher humidty, lower temperatures, higher N content of the seedbed, and shorter vegatative hours, provide optimum conditions for females.
Not to say that those conditions will make male plants turn female, but they claim that they will keep any ptoential females from turning male or hermie on you.

"is it alright to transplant a few days after its sprouted?"

that all depends on the size of what its sprouted in..if you can see
roots popping out at all you definitely need to transplant
asap.

if its sprouted in a peat pod or a 1 inch rockwool cube and you can
see roots coming out..or its planted in a 4 inch pot for example and roots are
coming out the bottom already then it should be an obvious sign for you
to transplant asap.

personally i like to have my vegged seedlings and clones fill up
a 1 gallon pot ..roots coming out the bottom. before i transplant them outside
into larger permanent pots.

and as for putting them outside..
it should be at least 55 farenheit at night at the lowest before you put them out.
not because cannabis can't handle colder temperatures..as it can usually live
until the temperature drops below freezing 0 degrees. im sure this depends
on the strain. however regardless of its ability to tolerate , survive and withstand the cold.. the plant will not show development until its at around 50-55 F @ night.

"does humidity determine sex"

the short answer would be no..a longer answer would be
humidity is a more of a variable when considering potency ..as it should
be high in vegetative growth and lower around 45 % in budding stage..to
achieve maximum potency humidity is absolutely a factor.

variables involved in overall sex of the plant are much broader than any one
specific variable.. regardless of humidity.

If the seeds are from a reasonable strain..stress on the seedlings
can be a factor..ideally to achieve the maximum amount of females
it is thought the minimum amount of stress is ideal .. as stress
whether it be cold , abnormal light, physical trauma .. seems
to induce males if the seedling is stressed in any way at a younger age.
you must consider also some strains are resistant to humidity and will
produce potent cannabis in high humidity as well as low.

a high humidity however is more desired in a the seedling
and vegetative state .. and would definitely not negatively impact
the seedling or inhibit its growth in any way.. just make sure
you drop the humidity to 44% in flower and no higher than 55%.

I transplant when I see 2 healthy serrated leaves for 2-3 days straight

be gentle, like you're carrying a glass vagina

I'd stay away from anything "Miracle-Gro" the nutes are uncontrolled... or of poor control quality...

If the pot you have it in is small enough, just wait a few more days till the roots engulf the grow medium, and then make the transplant.

I wouldn't go further using MG w/ anything other than germ/sprout, budget medium... my personal preference to encourage sprouting compared to rw and other mediums -

my pickyness during this delicate phase results in wasted soil..often

but yah, GT is right

Factors Affecting Sex of Plants

·

• Environmental factors start influencing sex the moment the seedling has three pairs of true leaves (not counting cotyledons).
• · Increased levels of nitrogen makes more female plants.
• · Decrease the levels of potassium to make more female plants.
• · A higher nitrogen level and a lower potassium level for the first two weeks increases females.
• · Low temperatures increases the number of female plants.
• · High humidity increases the number of female plants.
• · Blue light increases the number of females. Red increases males.
• · Low moisture in the growing medium encourages males.
• · Fewer hours of daylight (e.g., 14 hours) increases the number of females. Longer days (e.g., 18 hours) make more male plants.
• · Any environmental stress tends to yield more male plants.
