OldMac, Ya you are right, roots grow in the dark period. I am not stating what I mean again.

The stopping of photosynthesis with the loss of light allows the plant to concentrate on the root system, which I believe grows a stronger plant. As any study can be made to show whatever is desired, it is all a matter of opinion.

I prefer to save the money on the shorter time as I see no benefit in the end result with times other than what I use....18/6 and 12/12.

We should do a whole thread on roots, because what you see above has someplace in the pot down in the dirt. And we thought the human circulatory system was complicated.
WashougalWonder Reviewed by WashougalWonder on . 24 hour lights Folks, I see lots of peoples using 24 hour veg times. All in good in some situations for a short period of time, but the plant needs some total darkness every day to work on root development. You will slow root proliferation by using 24 hour lighting, increase your electrical costs, increase the 'wear and tear' on the lighting system and needs rest daily too...... I think you will find that most of the experienced growers have learned there is no additional benefit from 24 hour Rating: 5
