16/8 vs 18/6 Any Noticeable Difference, other than your power bill?

ShawnSunshine · Mar 12, 2022

I see that everyone recommends to grow veg on a photoperiod Plant at 18/6 until it's time to switch to the bloom cycle.

But since my grow area is near my bed, and I would like to save power as well and actually get some sleep..lol.. I'm thinking that for me 16/8 would be a better deal.

I've been looking at the threads and I see that some people do have pretty good success in fact even sometimes more depending on the light source.

So I would like to know if any of you have done 16/8versus 18/6 and what your thoughts are on that?

in veg you can give whatever light regiment you want to give, they'll grow just fine 4/4, 12/5/1/6, 24/0, 20/0, 18/6... even longer than 24h is possible... or irregular ones. they will adapt

Light type, wattage, configuration and distance at what stage of veg? A 23 W t5 will will do amazing for 72 cube tray at 6-10". And cheap. Once potted it becomes the variables I stated.

What are you trying to do with what lights?

Maglong 2000W (220 Actual Draw Watt Full Spectrum) lights in a 10 inch by 36 inch grow area.

Turn that down to almost nothing and hold the height until leaves look light in color or begin to turn up. Light is not a spec conformer. Still Too much for early veg. And power consumption is a few cents a day between 10 and 100% on true LED Quantums.

Okay I'm aware of this.

Currently my umols/par levels are 200-300

Which is the range for seedlings.

I'm actually running my lights at about 25%

But my question was.

Can I do 16/8 versus 18/6

If the amount of light time doesn't matter then why do people choose to do 18-6?

We know that it matters for bloom cycle of course.

I don't want to run the lights until 2:00 in the morning I have to sleep obviously.

So that's why I was thinking that the 16/8 would be okay.

Yeah but what is the ideal veg honestly?

I want to get the best yield and the best grow that's closer to nature.

In the summertime outdoors we get 15 hours here in San Francisco.

Am I really going be to be getting better yeilds by adding 2+ more hours?

I'm just wondering if it's worth it.

That's all, thank you.

You can run as low as 13.5 for a few weeks. Around your 3-4 node or 6-8 leaves it must be increased. This is due to demand and nature lengthening days in the spring.

I've never seen that from a seedling in almost 40 years. You growing high mountain strains?

Nope but there are alot of poly hybrid strains out there these days that will herm, flower or trip out if you sneeze on them.

A bunch of unstable genetics for sure. Still High altitude or latitude land races do exist. The basis for the Ruderalis craze. Perps advertising and fools paying for a name. Sad.

Purple Haze genetics ,they grow near the equator right? They are used to temp/light in the Columbia Area.

It's always 12/12 there or just about... So how do they not go into flower?

16/8 vs 18/6 Any Noticeable Difference, other than your power bill?
