I think as a preventative; i could run some aluminum or maybe copper sheet metal stacked on top as a heat sync. I do sheet metal HVAC so i can get ahold of material and do this so ill be adding that.

on a side note, to be able to fully drive these boards to their max wattage, with a heat sync made from the extruded aluminum from the HLG website, which drivers would i want for running 1- R spec on its own driver and 1- 4000k on its own driver?

I want to compare the cost of the drivers and possibly go with one that can drive it all the way up if i decide to use them for something else in the future

If you want the highest efficiency I think most LED's run most efficient at a reduced power level. You might look into that for your setup, more LED's driven softer.

I am buying a 288 rspec kit today , I went with the kit because I want the option in a later build to use these lights at full drive, perhaps in a bigger tent or something
I will hold off on the v2 4000k because I think it will make sense to test this out with just one LED at half the initial cost investment. After the chamber is built I may add in the second light

I am ready to order this kit https://horticulturelightinggroup.com/collections/kits
135W QB V2 RSPEC LED KIT
Meanwell HLG-120H-54A LED Driver.
Is this driver dimmable?

lol nevermind i scrolled down it says you can dim it. HERE WE GO PUTTIN IN THE ORDER!

fabricated the supply and return plenums today. I plan on adding a bunch of stuff but I'll be adding a plate at the return base for light trap and also a drain pan shallower than the base plenum to allow air upward. I am hung on centering the pan or offsetting it.. the supply plenum is off center as you can see from the bottom of the picture above.
this is because the hydro coil that usually goes in there has ports that go verically up. The pic above is actually upside-down from whats gonna happen. It's also laying on my floor but is going top be going vertically instead of this lol... hope the MS paint accurately depicts the whole idea.

the bubble wrap annoys me. I already have ideas of replacing this with a different material.. If I'm going high efficient I may as well go with the highest reflectivity VS easiest cleanup liner. I know flat white is nice, but im looking for a lining material i can somehow adhere to the cabinet.
I am also concerned with adhering the material to the cab -- I dont like using adhesives to build even though tape is clearly adhesive. I have thought of using washers+ screws from the outside-In.
Instead of point head screws , just pre-drill then send in the non-tip point screw and grab a washer with a nut to suck the liner in. Much more professional and no adhesives gassing off possibly into our precious grow.

pics incoming tomorrow i drank to much today again. I have to be sober tomorrow so I'll be uploading progress on this, and also my first edibles from some old product thread i did earlier this week (alcohol+ vegetable glyerine gummie recon)
haha also gonna post up some pics of my flowering plans indoors~ the last of the season

I am coastal new england so outdoors-indoors is a crap shoot..
I will do this chamber run indoors this summer and also talking to some fellows in the bodhi seeds forum. I have been interested in the seeds they have for a while. I would love a landrace strain that produces well , fluffy buds, even from other breeders but i've always wanted a landrace and figure try out bodhi.
my next indoor strain will be subcools new genetics. I have followed him a long time and will resume. He has always been an inspiration to me so i owe it to him to grow it out and do a real journal now that i've gotten real equipment.

but with that-- i still am chasing my original grow... a small compact spot to grow as much as possigble.
I am basically using a small cabinet of sorts to figure out how to maximize my gram per watt----- OVER TIME.
the GPW calculations are all bunk...
there needs to be a certain set point with this calculation
from this type of plant~ ready to transplant in this size pot with this medium, gets transplanted to this pot and flipped at this time and got me this GPW..

the reason being a 2-3 month plant and a 4month+ plant you see difference in output but if you add everything up are you REALLY getting more gram per watt over time?
some day we will all figure out this calculation but there are too many factors now to consider when comparing grows.

hope this thread turns out dope fellas. I have been reading into shit alot and trying to decide on how i'd like to grow these puppies..

Sips?
traditional soil?
Hempy?
Dwc?
Rdwc (remote res outside of chamber)

if i go the rdwc im thinking I might want an RO unit to start with, but ifd i go hempy or dwc, i may be able to get away with buying water . Im pretty sure somethings fucked up with my water where I am as far as chlorine/chloromine goes.

hollyweed, g13 crosses and hashplant are all bodhi seeds recommended to me so far for outdoors. I am in the US and also wondering what banks to get these from.
I am getting all the equip to build my micro setup soon so also looking into a small fat budded plant to grow. I will definately take advice for best Indoor compact horizontally and not super tall vertical strains and any high humidity/ cold weather plants for new england weather. must be bud rot/ bud worm/ mildew/ black mold/ nuclear resistant 8)

still deciding on what medium to use.. I have old ph/ppm meters from bluelab definately like 5-6 years old, lightly used.. Not sure if these are usable but

from what i understand the water here sux. If i went the hydro route, I'd be changing to RO water with all new hydro specific nutes and whatnot.

I think I'd rather do soil/organics so its down to this...

Rols/no till bed (this would have to accomodate young vigorous clones that get flipped immediately)
Party cup competition chamber (I love this fuckin thread)
SIPS bed (I'd maximize the size of the sips engineered to my room)
Simple soil pot / pots with normal soil and a pan ( the easy way out )

any suggestions welcome!

ordering some orca film today. its expensive but, the reviews on it and seeing as this is a high efficiency chamber I may as well go with the best of the best and not cut corners!
also ordering some light Yo-Yo's the lights coming into day just need to go pick it up and then I can start constructing!!

even if I get orca film I'm putting everything together first and going to deconstruct to re-line it after everythings in place. this will allow me to make this thing super legit and be worth keeping to me or possibly selling for what I think its valued at!

new plans include on the return base installing a light trap. I will be adding an air foil down from a grill that intakes from the front on the bottom and it will act as a light trap. On the exhaust the light trap will be a flex off the fan or something

also in addition to wondering thoughts on micro strains, and what medium to try.

what is the best way to apply orca film? I have read spray adhesive but i would rather not if i don't have to

Soo after a lot of work I screwed up my knee now I have some time for my grow hobby stuff

Here's the work I've done with my little hobby chamber.
I still have to figure out how I want things wired in and out of the chamber and am going to add in the green light still for night viewing
also need to add a legitimate drain pan . There are light leaks that aren't so bad, eventually I'll add some air foils to create light traps but for now I'm only using this for vegging babies.

I have used my lux meter and set these to about 6000 lux, I still have to add a timer I'm sure 24/7 light is going to be a little too much for these babies
The seeds are east coast stardawg from greenpoint seeds. I haven't used gu's genetics before and have heard both good and bad things so I'm going to test it out for myself here, and why not do the test with a strain that is newer to help the grow community out.

After the seeds popped soil I found a slug attached to one of the seedlings, and when trying to gently pull the slug off ripped the lil plant in half :(

other than that it was going to be 6/6 plants out of soil 4 days after adding them into a glass of water.

My question now is, how should i Dim this light there are two screws one is Io and the other is Vo. I tuned it down so the light is about 3' away and the plants are at about 6k lux. Am I doing this right and is there a thread on how to use lux to set heights and power of these lights??

also my other question is If I wanted to get rid of my 1000w HPS in my 5x5 and change over to quantum lights, what would be the best option? I was thinking something like 4 seperate lights for four plants in a 5x5, non-sog if possible ( i have a hard time getting to the back plants because of my living situation I cannot go in the side or back zipper doors only the front has access)

sorry for ranting. Here are the pics of it set up, with the orca film! Just some finishing touches left to do

Best swap for 1000w hps (single ended) would be either a hlg550 rspec or same parts divided up or a HLG600 from growers lights which gives you more wattage and its cheaper. Difference between warranty though.

Vo is the voltage adjustment and Io is the current , use the Io to dim.

I can relate to only having access to one tent door, my whole last room was like a game of Tetris.

I have heard the 550 is more a 1000se replacement in output but doesn't quiet cover a 5x5. So maybe better to go with a couple of the 320 xl kits. They are longer and more wattage so would cover better.

can i drop the light closer and dim it more to save power? and do you have any info on how to use a lux meter with the light or any info in this?

I was looking at the 320 xl kits they look nice i would probably do two of those or three of the 260 w kits or possibly doing something else maybe idk :D

the gorilla tent i got is the full size version I was hoping this is OK but wish I had the shorty for LEDS instead.

two 320's is good for a 5x5?

I have a lux meter app but its so far from been accurate I wouldn't like to say, different reading every time I press the button so its useless, plus im only just getting this strain used to the lighting, think its a bit touchy.
Flowered many crops but only since I set up in my new place have I been vegging with these lights, i would dim and then slowly move it up in power over a period. I really had to decrease my DLI to get them back to been happy and once i did they really started to grow well again.

Just not sure on the numbers you should be aiming for so hopefully rocket will chime in.

I would never worry about having too much height in a big tent. You don't have to use it.

but yeah you can dim and lower board to get same light levels. Just be bloody careful
I just don't know the ideal levels to aim for.

@Rocket Soul any advice for Nizza on setting up with lux meter for veg.
I know I had to seriously dim and reduce light hours, which I did last week and first time in age plants arnt light stressed.
I might not be the right person for this as our veg game is lacking, similar probs to you: plants go ape shit when we up light levels. We start somewhere around 8000 lux and move up to 10-12k lux when the plant can take it. Raising temps seems to help along with playing around with rh/vpd. Also looked like 3500K had less issues compared to 3000k.

I think it has to do with length of exposure, maybe you could try gas latern routine (veg 12 on, 5.5 of, 1 on, 5.5 off).

You could also try adding an incandescent or halogen or even a ceramic IR heater for giving so e heat and helping opening stomata. Again, all this at your own responsibility, our vegg is far from perfect.
It gets easier once the plants are a bit bigger and in larger pots.

Falls in line with what im seeing, we have a heat wave at the moe so temps are a few degrees warmer, just hope its not entirely that that's helped me and that it is the reduced DLI.

cool I just took my timer out of my 5x5 because I dont have anything going right now. I have it set on 18/6 now that they're above the soil

I dropped the light within 1' of the plant and dropped lux down to 5k
