Charge shipping now but the sale price went down to reflect that. Works out cheaper for the customer buying multiples items then.

When I bought Mars lights, I did not pay shipping fee, I am in Canada, I think they can also offer free shipping to UK customers.

My 3x3 tent is waiting for the next grow. that will be 4 Blue dreams with cbd(1.5 to 1), they popped today.

I wanted to ask...
What do you all think of lens hoods?
I have 90* hoods on my leds. I read where they really are not needed for a reflective tent???

yes....no need
Plus lose 10% or more of photons...

Would greatly appreciate some assistance. I'm planning on building an Fstrip build and am curious if the 2foot f strips will fit inside of a 2 foot grow tent? I tried using the search function but didn't find a 2x4 fstrip build that answered my question.

Thanks man! I'm thinking about ordering 32 of the 24v 2foot fstrips so I get a better rate. But am torn between getting all as 3500k or getting 3000k and 4000k and doing a mix. Of course I can't get that discount doing the second option.
Planning on running Hlg-240h-24a/b's (should I get a or b drivers) and running 6 strips at 75%. I like this idea because it doesn't have enough power to over drive them and seems more idiot proof. I'm starting with a 2x4 tent as my flowering tent but intend on turning it into a mother/ veg tent within one cycle and moving my flower to a full room. At that time I'll likely just build a new frame and dial the lighting back from 12 strips to 6 for the 2x4 and only run that tent on one 240w driver. (Is that enough?)
I'm interested in having each 6 strips framed , driven and hung independently. As I want to run multiple strains and dont want one giant rig that has to all be at one height. I'm super open to input. Trying to make the most informed decision here. Plan on using aluminum extrusion and thermal tape for heat mitigation of each strip and aluminum angle pieces for the frame.

A mix of 3k and 3.5k works for me.
Not enough strips for a 240h24B driver. Somewhere between 9-12 strips from my experience.
My example, 9 f-series strips ran by a HLG240H24B.
If you want to run 6 stripes than a LPV-150-24 would be my choice of driver. Not dimable and not as efficient as a HLG but for a 2x2 that would be my choice.

Nice set up. What size are your frames?

Thanks for your input Jarvild! Unfortunately I already bought the 3 240's so ill just Up the # of strips per driver up to 9 like you are running.

The left is 2'x3' the right is 2'x30", I'll tear the right one down and either change it to 3' or maybe a little longer as I like the coverage better with the longer frames.

Have any of you tried using LED's vertically? Similar to the Sun Cloak method?
I'm giving it a try, but since it's all 6000k I rather expect that I'll need to add some blurple into the mix. Just wondering if anyone here has tried it and what their experience was with it.

Yepp, here are a few peeps using LED vertically(some use COBs other strips). Use the search engine to find the threads..
I would use the 6000°k strips mounted vertically and would add a few warmwhite strips from above just like a sun cloak.
Bridgelux EBgen2 strips(1, 2 and 4ft length) are pretty cheap(7-14$/pc) and deliver 175lm/w or ~2,55μMol/J in 3500°K/CRI80.
What brand are your 6000°k strips? Samsung, Blux or cheap chinese 12v e3ay/amazon shit?

Thanks, Randomblame!
Right now it's cheap Chinese shit for trials. Running the 6000k. But if the concept works, I was thinking to switch out one side of a blade at a time to Samsung strips. I do realize that the yield may be lower than possible by using the cheaper lights, but wanted to give it a shot as a proof of concept. I have a couple of Meizhi 600 watt lights and was thinking I'd put above the blades to give the red and blue light ranges. But the SC grows I saw that inspired me only ran the 6000k with no supplemental lighting. So I was really curious to see if others had tried this single spectrum out and what they experienced.
I'm running Gorilla Glue in coir and perlite, and feeding every day with mostly AN PH Perfect trio and Cal Mag. Tried these lights out for 2 weeks on clones and they seemed to like it fine, so I made blades for my little flower room.
I guess I'm a moron because when I use the search function I only come up with a couple of things.

For a SC I would use Blux EBgen2 series 'cause they can run with no heatsinks even at max. current(1,4A). Especially for the vertical oriented strips its a huge profit.
3000/3500°=175lm/w 4000/5000/5700°k=180lm/w at 700mA nom. current. I've five 5000°k EBgen2 2ft strips running at 600mA/12w and will add them to my little 3ft² veg area next week.
2ft strips need 19,5v and 4ft strips need 39v, max current is 1,4A. Plants can touch the strips without getting damaged. With 1050mA and vertical oriented they stay below 50°C. A 4000°k 2ft strip at 1,05A throws out 3.850lm, the 3500°k ones around 3.500lm. And each strip is only about 7/14$ ..
EB Series Gen2 3000K@700mA(43,75mA)
QER=4.84 µmol/J
LER=331.66 lm/W
= 2.55 µmol/J
Not to shabby for such a cheap strip!
