VFV does stress plants, some people swear by it, others think it is too rough on plants. IMO the branch idea doesn't sound stressful, I heard use a paper bag instead of cardboard.
LolaGal Reviewed by LolaGal on . Veg/flower/veg? I dont have the capacity (nor are the plants big enough yet) to clone for sex, but i thought i read somewhere that you could change the light cycle, force it to flower to see what sex, and then put it back into veg mode. I also read that you could cover one of the leaves/nodes with black construction paper for the 12hr dark period and tell the sex. I would imagine this would stress the plant a bit. Im curious as to what everyone else suggests? Rating: 5
