I too was surprised to see so many males but hey, that's all part of growing herbs...gonna keep a few nice G13's to see if the sex will show...I've got 5 females so far and mebbe a few more when they show sex...on a lighter note, the royal limes is very mildew resistant, none of the ladies show PM...And here I am looking for a stud male.
The males usually show fast and well for me sorry you had such shitty numbers.
Kev, I've been growing in the slit posts for 16 years or more...I find them online when I need them...I've got hundreds of them all the way up to 7 gallons in size...Where did you get the slit pots or have you had them ???
