For me
oldjarhead100 I start to look at four weeks from drop of seed. That’s the wishful part. I am approaching 7 weeks from drop..still have 2 undeclared. Have been able to find the typical “stemmed ball†of male, including herms (damnit) .currently I loupe every day. I have found..not cloning or doing temp change or forcing with light change that:
A. The plants must be transplanted pre- topped, into 5 gal smart pots at about 4 weeks. If I leave them in the 5x5x6†plastics they stunt growth and don’t show sex...I can hear the boos but that’s my personal FACT...and a royal pain in the ass.
B. For me the ratios of 50% females is not true.
C. Also the misnomer that males after topping shoot up really fast and tall is not so...I’m sending beautiful bushy boys to Jesus as we speak and have had too tall suddenly girls.
D. It is often difficult to tell at the V of fan leaves if it is new growth or male ball emerging. until the male ball gets a stem ...and then there is / can be
a female elongated oval ( before pistil arrival). And usually a herm
SO my very good friend....at 47 days from putting seed...I’m still double checking...32 or so (100% germination) I have 8 to be verified ( not herms) females . Plus I backed up with one Jock Horror and one Jack Herer to be safe.
To conclude- I have to transplant into 5 gal pots before I can observe sex and that is one ritious investment. But then pull the root mass of the male...and transplant into the 5 gal pot the next hopeful
It is indeed berserk -o time.
You are not alone🥺
