anyone ever try experimenting with UV?

such as this light:

I would be interested to find out. Im building a led/pl-l fixture : https://www.icmag.com/ic/showthread.php?t=322619 and wondering if it could be a nice compliment to the center.

Good post. I have 3 5600k and 3 2500k 24watt 2G11 Pl-L bulbs, and it is so bright I have to wear shades or I get an immediate heapache. The plants love it too!

I changed my lites from all on the top to all down the sides. LightCicles are the BOMB!

Here is the Pron!

Boleman will probably know better but my personal preference is to mix spectrums at all times (unless you have a seperate cuttings cupboard then maybe just go for an 865). After all, sunlight is full spectrum and the poor plants grow up in a warped enough environment as it is without depriving them of a full range of light.

As an aside, whilst the early LED lamps used the limited set of wavelngth values most necessary for photosynthesis, the general consensus now seems to be that broad spectrum cobs are better. Of course, fluorescents have a broad spectrum coverage anyway so the issue is not quite so attentuated as it was with LEDs.

So, for those two Kelvin vlaues I'd have two 6500K and one 2700/3000K for veg and vice versa for flowering. Of course, you could always go for one lamp fpr seedliings/cuttings, two lamps for veg and then use three for flowering. Save yourself a little bit of leccy - though for us micro growers, it may not be a concern.

This is more prevalent in soil grows.

Yup

Go figure.

Nope, not in Hydroponics, but have noticed that with soil micros. Try using those bulbs for flower, and a lower spectrum for vege. Nothing wrong with dense buds, though. If you have the right airflow, that is...

Sorry for the delay!

Sorry for the delay!

this is probably more of a general grow question, but i'm planning on using PL-L's, so it sorta works. i want to use 3 55w lamps. initially i was thinking 3 6500k lamps for veg and then switch to 3 2700k (or 3000k, depending on what i can find) for flower. is this the way to go, or would a mixture of spectrums be better?

Answered above!

I'm having trouble figuring out the wiring on my PL-L fixture. My set up is a fulham workhorse 8 running 3x55w lights.

I need to know two things.

1: fulhams wiring diagram 26 shows two red hot wires merging to one before the double feed into the outside pins.

Can I hook up the two red ballast wires directly to the leads comming out of the socket pin holes? I read in one pl-l thread a member contacted fulham and they said not to connect two ballast wires directly to the socket? I can't imagine that I need to hook up two of the ballast wires to a single wire before heading to the socket, which splits again. Seems like there would be too much load on the single wire. I realize I can hook up one red per light and be done with it but fulham shows two as a possibility and i read that this overdrives the bulb creating more output. The consensus never seemed to manifest in the thread though.

2. jumpers.. I see a lot of different sockets, I'm using ones with 8 rear terminals.
https://www.1000bulbs.com/product/53759/SOCK-EG286SC.html

it seems there are 8 terminals 2 per light pin. Do i need a jumper wire between these? or is it red one side yellow out the other. Diagram 26 shows a jumper on the bottom sectional view for linear lamps. What do I need to do for these sockets?

Alexonfire asked earlier
https://www.icmag.com/ic/showthread.php?t=132787&page=40
I thought his middle diagram was correct as per the fulham specs but now Im confused and I don't see a clear answer, especially if I want to over drive with two wires and my sockets are also different.


here is my light and socket.

Summary: Do i need to put a jumper wire on my sockets and how do I correctly hook up two red wires per light?

Thanks

Vertical scrog

Vertical scrog

Hi Boleman - thought I'd share a couple of pics of plants vertically scrogged around two 55watt pl-ls. Only on the second time of using this exact method. First occasion, had one plant either side , wrapeed around the lights, this time have two plants on one side scrogged and running a"compare and contrast" on the other side with plants flowered from cuttings at between 4 and 6 inches, in tall, narrow, 1.4 litre pots. Haven't got it right yet on the plant side so the scrog is a bit sparse and, obviously, will take a few turns round the block to find the sweet spots for the various plants on the cuttings side.
The first pic is a blue OG, the second th esame blue OG and a tangie kush on the other side and the third is a Lilly from Original Delicatessen and a Peyote Purple form Cannabiogen.

what's up folks. are ppl still growing much with PLL these days? i really like the form factor for a micro scrog box. not sure if i should go with the cfl/reflector or led replacement, such as from ahsupply. any thoughts on the perfect micro cab setup? i've got a produce box about 20w/l x 12h, interior about 18 x 10 respectively. can you do anything with this space? i was gonna flip it on its side so it's taller. any advice much appreciated!

 

[cannanaut]

Hello bebopson! There are few folks still using pll lights. I use pll lights too and they are really good. You can have 1-2 ounces with 110w of pll. If you want better yield look for cree cxb cob leds. I had good results in space similar to yours with sea of green method. I plant 21 plants in beginning of the grow and then select 10 plants. They are grown in small beer pots with organic soil 12/12 from seed. Best yield I got is 8 grams/plant. It is about 5 grams/plant on average.

As above Bebopson - plls may not be the latest thing but, in comparison to other cfls they are more efficient (55 watters producing around 80-85 lumens perwatt dependent on spectrum as opposed to 65ish for most other fluoros) and have better penetration. They have excellent spectrum coverage, are cheap and readily available and won;t raise any eyebrows when you buy them.

You will definitely need to sort out your ventilation growing in such a confined space as your biggest enemy wil be heat. If you can afford the set up costs, cobs will give you a lot more light, less heat and more harvest per watt but plls will give you good smoke and, for me, more than adequate amounts (around 0.5g per watt is usual but you may achieve a little more).

There are a few other relevant pll threads you might want to look at. Check out Garuda's in particular for info on a single 55watt pll grow and boleman is always here to give you advice.

Enjoy!

Siiiick!

This is a cross post but anyway. 4x55w PLL 1x150w HID dualspectrum.
12/12 from seed. Perpetual sog (just started).
370w (+570w/m2).

I think this is good use of 370w.

 

[Boleman]

It is a Great use of 320watts! If you put the Pl-L bulbs vertically in each corner, then de-shield your HID and Center it you will get your best results.

Like my use of 144 watts here:

Hello,

Just joined the PLL club, lots of good info here.

This paper on reflector design is excellent.
It provides a plan for a 4" wide, 50 degree reflector that puts the bulb vertically, page 5.

Angling the tip of the bulb down by 3 degrees can improve efficiency by up to 15%.

https://buildings.lbl.gov/sites/all/files/lbl-35253.pdf

never got around to growing with them, but always wanted too, always wondered how positioning the bulb would work out,
as surely you're losing nearly 50% of the PLLs surface area if you have them flat face to the plant;

I ordered a set of 5 55w last year but when i recived them i noticed that I ordered the 24w ballast and not the 55W

Is it worth using the 24W? Is it enough with say 3x24 for a small veg box?

Yes.

I use two 36W in my small veg box and am satisfied
with the growth rate/heat ratio.

Not interested in LED at this point, PLL for the win.

PLLs are really nice for vegging but also are capable to produce nice medicine. When dialed in buds can be pretty dense and sugary. Love to grow Sea of Green with plants in party cups

I have a question for the PLL club!

I got ahold of some cheap bulbs recently. and I have 3x Workhorse 8 ballasts at my disposal.

I was thinking of putting 4 bulbs on one ballast, and three bulbs on the other. Per Fulham I can do up to 6x 36 watters per ballast, but I was thinking if I split the load it'd run cooler.



Sylvania Dulux L 4100k 36w
I am working on a mini fridge, would 7 of these, (looks to be about 252w) do decent in there?
