Actually I want the Chem d BX 3 by Insane Seed Posse but can't find them anywhere.... I really want a Chem d cut but can't find anyone holding it . >:( I got peeps in Cali checking dispensaries for a Chem cut .

Do you think your problems with having males (especially with the feminized seeds) is a result of going 8/16?

No they were sort of expected.
My friend ran a pack of seeds and one of the females selfed and the resulting beans are what I popped.
If the light cycle caused males then more or all would have balls.
This run I only had 25% male

Not many peeps stopping by to complain that I'm not taking enough pictures this time lol
Oh well I guess it's better that this turned back into my personal journal anyway.

This run I'm super excited to see even the lower buds building up and stacking the frost early. The larger pots and switching back to an a and b instead of good ol earth juice.
If early smell is any indication it looks like I'm going to have some nice New Years smoke.

I've been doing some thinking along the lines of a variation on what you're doing here, if I may;

I'm designing a modular LED system that allows me to alter the effective PPfd delivered to the canopy at will. Current consensus thinking is that 850 PPfd, give or take, is about ideal for growing cannabis indoors. It can be done with more, but returns begin to diminish. Why? Well, another thread got me thinking... this one talked about how plants actually shut down to some extent during midday because they're getting too much light to process effectively. Perhaps as we do the same indoors, the same thing happens?

So here I am, wondering if a shorter but higher intensity application of light, say as much as 1250 PPfd, might get the best of both worlds.

I'm thinking about lighting half the growroom for six hours at this high intensity, then lighting the other half the same way for the same duration, then off for the usual twelve. I'd ensure that there'd be plenty of light spillover to keep the unlit side from entering its dark phase, and overall energy savings could be substantial vs simply lighting everything all day.

Since we're using higher intensity lighting, my bet is that total yields will not drop by very much and perhaps by less than the 25% energy savings achieved in both lighting and HVAC costs.

Sounds awesome
I can totally see how it makes sense.
The reason I decided to do this experiment at all was because I thought that in a usual 12/12 with the same wattage the plants definitely seem to be under a state of no growth and maybe even show negative effects.
Everyone refers to the leaves angling up and looking happy and I've never seen that more under any cycle as I do now.
They seem rejuvenated and excited to grow and for the light to come on.
Plus there's the heat difference and lack of it with shorter cycles.
I too am building an led light. Well soon as the parts come anyway and my light is going to be a bit different than most I've seen posted on riu.

I hope you do try it and if you do and decide to journal it please post a link or tag me cus I for one would love to see it.

All it takes are for a few tiny ideas and attempts and progress happens

Lol that's what I'm hoping for.
Kinda curious how long these are gonna take. They seem further ahead than I expected. Still a lot of time to pack on weight.

Got a phone call today from a friend begging me to make f2's of the space phantom. He called in a favour for letting me use his other room. I only have like 60 of them left so I may germ a big tray and pick the best male and 4-6 females and throw them in another cabinet and let them do their thing.
