Graytail's 4th Perpetual: 4x4 Samsung Panels

[dynamo1]

Which cross is this? Is it one of yours?

No It is yours, Your winner, I'm going to clone it to keep a copy of the strain then re cross back with Carnival. That was the plan we discussed.

 

[Graytail]

Awright!

I wasn't sure if you had started on that stock. Do you have any of your DCs running now?

 

[Van Stank]

Yup.... agree 100% Gray.
Big pots +lottsa light= big yield!

The only thing about dealing straight with China is the shipping. It'll run over $100. So small purchases get expensive. That 304 board they have is nice - includes 660nn red diodes, too. I'd only suggest that you try to save some shipping cost, but that example shows you the rough costs per watt. That one is 230 watts for $163 = about 70 cents per watt. They have several board sizes, from 128 diode to 800 diode. Lemme know when your trigger finger gets itchy.

The 3 gallon pots haven't been more thirsty than the 6 gallon ones - need water every 3-4 days. I never really thought about it, but the plant size is smaller, too, so it makes sense. Keep in mind the small yield. Even the long tall sativas only yield 2.5 ounces at best. My mindset is foliage per gallon of soil, per biota population. Since HB is all about the soil, I see the plant as cubic canopy volume per gallon. You can grow it tall or grow it short, but it'll only give you as much produce as the soil can provide. So in my mind, the plant can't grow so large that it would need water that often. Obviously, that's not a hard and fast rule - I've had a 2 foot plant in a cup that needed water every day.

I grabbed 1 of those 304 boards pre assembled, I plan on running it over a single auto in the vegg tent, once I flip my current girls.... if they make it

 

[Graytail]

Excellent choice!

They're spendy one at a time, but it's a great light!

 

[dynamo1]

Awright!

NO, My first attempt was a failure, the DDA pollen didn't take- maybe to old. I will try again when the Carnival being sprayed with CS produces pollen & then also pollinate the DC3 from you & my Nice Devil. fun ,fun ,fun.

Hi Gray, Got to say I really enjoy your thread, your plants are always awesome, and I like your method. You also seem to know the QB panels well. I think you seen the light rack I built ( pic just in case ). I sat down a couple times to ask you questions before I bought but I seriously didn't know what to ask, all the units of measuring light and this and that makes my head spin. But now that I got them maybe you could help me use them.
The room is 4' X 4'.5" and it will be the flower room. ( veg room for now )
I have 2 racks like this 3 x 304 with a HLG 120H C 1400. ( only using 1 to veg right now )
As a flower room the plan is 6 , 7gal. pots, 2 rows of 3, a panel for each light. I see you listed the wattage you have your rooms running at ( this is where my head starts to spin ) Is that full throttle? How hard do you think mine should be run, this is for when its a flower room.
I plan to use my old 1500W cob light to veg but I wanted to play with the new lights so I am using 1 rack to veg 6 , 1 gal. pots. Same question I guess, how hard to I run them in veg and how close do you run the lights from the top of the plants at that setting? Thanks Gray, hope your weekend was good.

Thanks, Eggs!

It's great to see you take the plunge into Samsungs! Ok, what you have is a driver that can supply 150 watts into as much as much as 108 volts - perfect for three 304 diode panels in parallel. They use about 108 volts and they each get 50 watts - about the same power I run mine at. In fact, I have a set of three running on the same 120H-C1400 driver. At that power, they're very efficient.

But I'm running 14 panels in my 4x4. You have 6. So to get enough light for your space, you'll either have to run the panels at higher wattage or get more panels. So, right now, you have 300 watts in drivers - two 120H at 150 each. I'm running 670 watts with 4 drivers.

Wired in parallel, each of your panels is getting 1/3 of the 1400ma = 50 watts. If you add one more 120H-C1400, you could wire them into pairs instead of trios, and each panel will get half of the 1400ma = 75 watts = 225 per fixture = 450 watts for both, which is a little dim for a 4 x 4.5. You should shoot for 650-700. If you can supplement with about 250 watts of blurples over the middle, you'll be golden in bloom.

Ask me anything, if it's not clear.

Oh, and when I was designing the space, I decided not to get more power than I needed and just run everything at max. I bought A-type drivers, so I can use the built-in screw adjustment if I ever want to turn them down. They are a bit too bright in late bloom, so maybe I'll fiddle with 'em sometime, otherwise it's usually just as easy to move the plants down.

DevilsCarnival6 got the chop today. She's a small one, probably less than an ounce, but she's pretty. It's another purple pheno, very similar to DC2.

Wowzers!!!!!
That's intense. I'd like to get me some of that beautiful purple

Whats the effect?

 

[Graytail]

All the DCs I've tried have had a similar high - a nice blend of Carnival buzz with a mellow fade - good social pot. It doesn't have the punch or the legs that Carn has, but the flavor compensates. This one is blueberry muffin. Others ranged from lime to plum. It's great for "sipping on" after I've set a base buzz with something else.

Wow 14, I guess I seen that in your post but I wasn't sure your room was 4' X 4' that's awesome. How close are your lights to the plants? So when you talked about adding 250 watts of blurple you must be measuring something different then the 5 , 300 watt cobs that are in my old light.

 

[Graytail]

Ah, I didn't check things out. You've been running COBs then? Ok, well, they'd be great in the middle, too. You could also replace your two drivers with two 320H-C2800s. That would double your power to 100 per board, bringing it up to 600 watts total.

One of these days I will need to LEARN this LANGUAGE

Thanks Gray, another bonus I like is no fan noise.
I'm getting confused, when you are talking watts from the power supply it makes sense, but for example when I read on the side of my old cob light it says 1500 watts. Maybe that's right IDK.

 

[Graytail]

1500 watts of COB would have bleached anything you put in there - can't be that much.

I have to keep my canopy at least 20 inches from the panels, 24 is better. They don't get burnt - they just get too much light. The 304s are pretty intense. I also have 120s for veg, with the same board size, and I can get within a foot of those.

 

[Amy Gardner]

have 120s for veg, with the same board size, and I can get within a foot of those.

So this sparks a question then.

I have mine currently about 20” inches under the same boards - which I use for veg and flower (the 120s).

In flower, now, I have them getting a bit over 33watts each (was back around 25each during veg).

I keep looking at the plant and wondering if I could maybe have it higher, or crank the driver a bit more.

Should I try raising the plant up a bit and see? Seeing as this grow is kinda about seeing what works (unless it’s completely inadvisbale )

 

[Graytail]

I honestly can't recommend it, Amy. I keep finding out that these boards are brighter than I think they are. Under the 120s I try to give the tops 20" or better. I just get a tall one occasionally. Yours are a little less intense, though, so you could go closer.

 

[Amy Gardner]

Yep- that makes sense. They are suhuuper bright!

I’ll measure today to be sure wheee it’s at, but I’m pretty sure I settled at 24” and then some of the colas grew a few inches

 

[DrDoob]

Geeze my lights are like 6”-10” from the tops. Guess I should raise them a bit.

 

[Graytail]

I bet the tops will look healthier if you do. I'm pretty sure I'm at saturation levels at 24 inches. That's 40 watts/sqft in a 4x4.
