Pros and Cons of 24/0 VS 18/6

[lilo]

If lighting is too intense/wrongcolor that's where the plant benefits from dark period. HPS alone is wrong to start with and keeping it too close is even worse.

In order for a plant to grow and develop properly, it must balance photosynthesis, respiration, and transpiration. Left to their own devices, plants do a good job of managing this intricate balance. In an indoor garden where the grower is creating an environment, this balance can be tipped without a fundamental understanding of the processes themselves. If a plant photosynthesizes at a high rate, but its respiration rate is not high enough to break down the photosynthates produced the plant
can have a burnout (i.e. light on 24 hours a day). On the other hand, if respiration is much more rapid than photosynthesis, the plant won't have adequate photosynthates to produce energy for growth. Hence, growth either will slow down or stop altogether (i.e. low or inadequate light levels or photoperiods).

So... if you got 1500ppm co2, an aeroponic setup, the right amount of nutrients, an RH of 60-70% and temps from 78-83F, ya 24/0 sounds like a good idea

I have been keeping my vegg light on all the time, i can't stand to see my babies droop when the lights are off.

For those of you who do the 18/6, does the 6 hours of darkness have to be uninterupted and have no light leaks?

Just grow your plants...

Not at all bro. for years I usually leave the regular room lightbulbs on during those 6 hours the big lights are off...... have had cloning fluoros in the room that never go off when all the others saving energy do..... and have hardly ever closed the door to veg rooms, with light leaking all in there.

Light leaks while your big lights are saving energy shouldnt give you a problem at all in veg.
