Several things. 1) Why consume that 6 hours of energy when you can achieve the same results running your lights for 18 hours rather than 24 hours. 2) The ambient room temperature will be hotter because there is no period of cool time 3) Your room will be generally dry therefore your RH will be too low which could stunt growth of your plants.
Lol that is not true. There are MANY people that veg for 24 hours and get females. The only advantage of 24 is the plant will grow faster. More light = More Photosynthesis = More Growth. You are sadly mistaken if you think 18/6 will provide the same amount of growth.
It is true, at least to some extent. Granted a 24 hour light cycle wont put the rate to 100% males, but it does encourage male plants. I have a high times that has a little article about it and after reading it i checked up a bit and i found that it is indeed true. In fact i have a friend who had about 18 plants growing under 24 hours of light and he wound up with only 5 females. Im sure if you do a little research on it you'll find it does hold some truth
I did 24/7 light to my sproutlits there was 15 total 2 were male out of the 15 after i find out the sex I go to 18/6 I think the plants look happier after staying awake for a few weeks straight
If you put a feminized seedling under 24 hour light it WILL NOT turn it male. I don't give a shit if it high times, time, people, forbes, or whateve magazine your reading says so...
I did 24 hours of light during veg and got 4 females out of 6 seeds using 12 26 watt cfls. I only vegged for 4 weeks and they were about 12" tall. I don't think they would have grown so fast under 18/6 but then I haven't done 18/6 so I have nothing to compare it to.
