Samsung strips still going

Just pulled another four plants from my 4'x2'. I've got a perpetual harvest going, so there are four new plants next to them. Each four plants is under 200W of Samsung 3000K H-series strips (two frames, 24x2' strips, 400W total), and I've been averaging 3+oz per plant (x 8 ) with this set-up. Some plants produce more (up to 5-6oz), some less, but none are less than 2.5oz per plant dried and trimmed.

Got a bit of variety going, but I'll only be keeping two clones out of these four: back left is the Wappa (keeper), and the other three are Mental Floss. Front right with the big buds is the keeper Mental Floss. The other two lean more to the Blueberry side. Nice smoke, but not great yields. The keeper Mental Floss has very nice buds and good yields with an excellent "dreamy" high.

New plants in the front are "Swizzleberry" (Swiss Bliss x Schnazzleberry). Lots of Chimera genetics in this lot. The LEDs are obviously still doing their job.

greasy. that mental floss keeper looks great.

I'm still on the fence on COBs and LED's because I have a fairly large room and cost is a consideration , but if I was in a tent I wouldn't hesitate ...Nice work

Yeah, it's the bomb. This is the second run for these. I like to run clones a couple of times just to rule out any variables before I make a final selection. The keeper has the indica structure and hard-hitting stone of the Mental Floss mother, but it also has that underlying head high the Blueberry father is famous for. It's real thought-provoking weed - functional even - and great for just enjoying being stoned. Mentally active, but there's no doubt you're fucking ripped - hence the "Mental Floss" name, I guess. Lovely taste and smell of astringent blueberries, too.

The Wappa is a pretty good plant, too, as it yields nice solid branches of sticky, stinky bud with an excellent "Happy" high. Great commercial weed, whereas the Mental Floss is more connoisseur smoke.

Here they are with a bit more colour.

Nice! Looks great. I’m running a similar set up that l just purchased recently and completed my first harvest in.

I had 2x bloody skunk autos that I just chopped and each pulled over a Qp!

4x2x6 with 8x f-series 3500k strips mounted with a 350w meanwell.

Ac infinity cloud T6 fan with a 6x16 carbon filter.

Currently have 4 plants in there all cookie strains besides one. Very happy with my purachse! Glad I can see the potential my tent will have by looking at yours lol!

Picture from the other week before I got my carbon filter and exhaust fan.

Fill that tent up!

I've got F-series strips in my veg tent. 4x double-row 5000K driven by a HLG-240H-48A. These are old photos.

Very nice! It’s acyually very filled up now! Lol. Almost too filled up... there’s 4 plants in it in, there is only 3 in that picture above. Colas are packed from left to right in my tent.

I have a 2x2x4 with a “300w” viparspectra blurple led... that tent is about to be taken down soon.

I’m planning on buying another 2x4 tent with a some qbs or build my own strip light.

Sorry, I mean "Fill that tent up - yes!" (It's hard to get the right tone across online sometimes.) I wasn't telling you to fill it up - it was more of a cheer, lol! Once those plants start budding, they will definitely fill it.

Oh lmao my dumbass... my bad haha. Can’t imagine the dry weight I’m going to pull from this tent this time around. If I got a half p from a unfilled tent with two plants, I wonder what this harvest will bring! Very excited to find out! Your plants look A1 by the way. Very healthy looking, that’s something I need to get better at over time. Reading my plants...

Hello Mr.Connery
Can you tell me what distance your light have to the cannopy?


And did i get it right,
You have 12× 2 foot samsung h-strips
So each panel have 6 strips ,each strip rund on 40w ?

I am going to add a couple strips to my 2.5x4 tent. Right now I have a triple 320 qb kit in it. Thinking of adding 2 or 4 SI-B8U201B20US. And switching out the 320 kit for a 260 kit. I really like your setups! Think with mine 2 4ft strips with the 260qb kit between them should be good or should I go with 4 4ft strips? I have an extra hlg 240h c1050a driver.

Hi mate, no there are 12x 2' H-strips on each 2'x2' frame (the frames are actually 600mmx500mm). Here is a photo of the two frames - note the strips are mounted two at a time in series (48V), and then six parallel on the U channels (7.2A) - you can see where they are wired together at the bottom. Each strip can be driven at up to 28.8W, but I drive them closer to 16.5W each:

I guess it depends on what sort of flexibility you want. I built two 2' frames for my 4'x2' so I could hang them at different heights for a perpetual grow. You can obviously see how I hang them in the photos above - which suits me fine. I also designed the frames so they could be bolted together (see below), but in reality they have always been split and I have always run them at different heights as, even when I didn't have a perpetual grow growing, my plants were rarely the same height.

4' strips are convenient (less wiring), but 2' strips are more rigid - possibly another consideration. Is there any particular reason for you wishing to swap things around? I would have thought the 320 kit would be OK. I also prefer 3000K or less strips purely for flowering.

My tent is only 5ft tall and the 320 kit doesn’t cover that extra .5ft of width as well since the light ends up being so close to the canopy. Have the 320 kit running at 260 watts and still getting some light stress. Figuring with the 260 kit and some strips it would help with coverage and I could dim the 260 kit down some.

Would you simply remove one board and run it as a 260 over the triple heatsink? Or were you thinking of getting another 260 kit? Boards are good for 1-plant grows (one board per plant) or for larger square grows were you can use multiple boards spaced out, but for scrogs, rectangular and narrow grows, I think strips give better coverage - unless you use multiple boards and run them quite low. That's the main reason I ran with the H- series strips over six channels for my flower boards - even though it was a bit of extra work - as the cost was similar compared to the F-series strips, but the diodes are better spaced for heat and light spread. I still get slight bleaching with my frames set to 200W each, but it's really a trade-off between bleaching a couple of taller bud tips and getting better spread and penetration across the bulk of the canopy sitting below. I don't have time to get too anal about tying branches over and keeping my canopy uniform, otherwise I could obviously run the strips lower and at less power for better efficiency.

I guess I’ll fill you in on exactly what I got going lol.
I have a 2.5x4x5 tent with the triple 320 qb kit.
Then a 4x8 tent with 3 260 qb kits and 4 132 QBs
The 320 QBs kit would work well if my tent was taller I believe but it isn’t lol. So I am thinking if I switch the 320 kit for a 260 kit then add a couple strips on each side of the 260 kit, and dim everything, it will give me better spread and less light stress.
Does this seem like a dumb plan lol?

ok new idea
thinking 4 BXEB-L1120Z-35E4000-C-B3
wired in series with HLG-120H-C700A
be like $100 for some supplemental lighting
would this work?

You could. Personally, I'd probably run them in parallel with something like a HLG-120H-36A. The 36V driver will drive up to 41V at 3.5-3.7A (at which point the EBs will have a forward voltage of about 39.5V with a forward current of about 900mA per strip). That would be about 140-150W total and the A driver is adjustable, so you could turn them up or down as you liked until you found your sweet spot. The constant voltage drivers just give you more options as they can be driven a little higher. All my strip builds use CV drivers with parallel strips (though my H-series have two in series and six in parallel per frame).

Excellent setup and the plants seem to just love the strips in these smaller spaces.

I need to watch some YouTube videos so I can understand this. What would be the difference in using hlg 120 36 vs half 120 42?
