My 8hr flowering experiment

Krusher · Dec 13, 2015

Great thread! I am just about to begin my first grow and after reading through this entire thread I'm pretty much convinced on starting off using the 12.1 veg cycle with a reduced flower time. I'm torn between trying the GLR or straight 8/16 for flowering. The lighting I'm using is 5 2ft T5s along with a 2 LED and 2 UVB bulbs in splitters. Do you think this is enough light to try either if these methods with successful results?

I'm hoping to add an LED at tax time (not sure if I should go California Lightworks or DIY) I still need to research more on these.

Thanks for sharing your results. Can't wait to see final weight.

I'm glad you enjoyed the read sir
I would say that you definitely have enough light to veg 12:1.
Whether it will produce enough yield in flower is a question I couldn't answer.
By what you've said it sounds like you got the right idea. Veg 12:1 for a month or however long it takes for you to build an led diy cob light

Good luck

DIY your COB LED, FTW!

Could you point me in the direction of some good DIY COB thread builds or grows?

The whole LED section on RIU?

Shit tons of great info and people happy to help the serious- with their help I'm building a 5kW COB LED array, no way I'd have tried it on my own!

Two more days of light and then I'm pulling the plug.
I will give em two days of dark then chop.
Not expecting a huge yield but I'll have enough sticky icky to get me through the holidays.
Now I just gotta find some ho ho hoes

Now that you've got the necessary mistletoe, I do not think that will be a problem!

Chopped mine yesterday lol I let a none smoker smell the Space Phantom , she called straight skunk on it...only one person said they smelled grapefruit lol maybe after a good cure the grapefruit will come out like in yours.

I thought you still had a couple weeks? Oh well congrats on getting to harvest it anyway. Hopefully it cures well and your happy.
Cheers

Yeah they got pulled about 9 days early..no biggie... things got jammed up so I picked them and had to move the new babies to that spot .

torontoke · Dec 15, 2015

Pulled the light today
I will give em a quick trim n hang tomorrow.
Moved the space phantoms to their new home and will put the grandpas breath and honeybee into veg pots tomorrow.
One of the honeybee babies keeled over and died so I may throw another bean in the mix.

ttystikk · Dec 15, 2015

Your experiments have me thinking about an old Heath Robinson trick; lighting the plant on one side for six hours, then on the other side for another six, and then twelve in the dark.

I think I've mentioned it before, but it has me thinking about it being another way to get more yield from the plant without spending more energy.

torontoke · Dec 16, 2015

Only one way to find out bud.
I personally think yield is most dependant on genetics, pot size and veg time.
This run im happy with the 8" main bud size. And these weren't vegged very long so with some more topping training and time I'm certain that 8hrs of light would flower a worthwhile yield.
When I switched from 1 gal to 2 the yield looks to have doubled.
My buddy runs his space phantoms in 5 gals. And averages about 70grams of superb bud and more popcorn and shit then he wants using 8hrs.

torontoke · Dec 16, 2015

I suppose it really comes down to what it is exactly your after.
Making as much bud as possible or as much as possible as cheaply as possible.

torontoke · Dec 16, 2015

My motivation in the experiment was bang for the buck and I'm convinced.
Using the glr for veg then 8/16 I'm officially using 50% of the energy used during a typical 18/6 12/12 grow.
Now as the math guy brought up ten pages ago that the energy savings per month aren't worth 20% of the yield loss to me that's irrelevant.
It's not the monthly energy savings I care about its the cost of energy storage. Or not needing more batteries.
Now if I ever get the led going and can manage it all the way I think I can things will get interesting.
Even though I don't buy into grams per watt I think 2grams per watt using 8/16 is possible.
This thread may be 800 pages by then lol but it will get there.

They're already pulling two grams per watt. Also, @Growmau5 in the LED forum is already calculating total power consumption per gram of product, which is the metric you want to use. He just posted his latest results, fascinating stuff.

Something like 2.5kWh/g... which is the metric I believe you want to strive to minimise.

torontoke · Dec 16, 2015

I meant once I'm getting 2grams per watt. I'm sure that there's many guys pulling 2plus but I guarantee that's using 12/12.
We shall see I suppose.
My led will only be around 200watts and I'm hoping to yield as much as my buddy gets with a 600hps

ttystikk · Dec 16, 2015

Here's that thread;

https://www.rollitup.org/t/mau5capades-builds-grow-journal.881192/page-25#post-12153784

They're killing 2gpw already.

For your interest, you must go ultra efficient. Either @SupraSPL or @REALSTYLES or both have tested panels that run at or over 70% efficiency. Panels like these cost beaucoup dinero, because they'll use six to eight times the number of chips the wattage normally calls for! Buuuuuuut... efficiency like that is worth the up front cost in your case because it directly translates to lower installed generation and storage capacity.

I think they'd both be happy to offer some suggestions about designing and powering such a setup.

Best of all, these lights still provide excellent intensity and spectrum balance so that during lights on they're getting everything they need to produce great flavors and fully express their characteristics.

torontoke · Dec 16, 2015

I appreciate the help tty but honestly after that ass clown came on about nonsense in the last thread you tagged me into I think I'm done with more threads lol.
I refuse to argue stupid points like less than 12/12 gives u 50% less thc. And that was a mod Fuk me.
I've lurked in the led section before I think I soaked up all the info I needed.
Besides posting in those threads got me little to no help in the past.
I know what I need for this cabinet and I tried ordering from king brite but he emailed me that he was sold out n waiting.

I will get it sorted

torontoke · Dec 16, 2015

Wow tried to do a complete trim in one go but the ol back isn't what it used to be.
Took a break and put the 2 honeybee and 4 grandpas breath in one gal pots.
I will give them a couple days of 20/4 then I will put them under the 400 on 12:1
