Make sure they are not testing for PED's - still no concentrates for rec sales?

I think the pool scene is not testing yet, thankfully. Shamefully, I have not even been in a store yet. I have way too much high quality in reserve (A great problem to have) I hear just flower for rec. I will know more after my maiden visit today!

Last I checked you can get a 250w led on Amazon for $120ish

I guess i just picked the wrong lighting company lol...

[Bobby Stainless]

My next fixtures will be Double Ended Gavitas.

Input wattage is hardly the determining factor for the value of LED lights. You need to look at the PAR (photosynthetically active radiation) output over a given area. For example some lights will require 250 input watts but need fans to cool the drivers (instead of driving photons), and have a footprint so small that you need to hang it 4' above the canopy to cover even a 2'x2' area. So the cost per volume of photons suck.

Kind LED is a classic example

Yeah, fuck Amazon. Buy from a local wholesaler.

[Game Over]

I was looking at getting some of these for the greenhouse

300w for $128 shipped.

Are they shitty? In the comments a guy says two would replace a 400w HPS.

[highangle]

I wonder what the bugs will think of a magenta greenhouse glowing through the night?

Never used LEDs, probably won't until some design emerges as a standard. The whole LED segment still strikes me as a bunch of garage tech and snake oil with a lot of anecdotal hooey and dodgy side-by-sides to back it up.
HPS works.

I've got a few extra if you want to upgrade sooner rather than later

Shit didn't think of bugs being a issue in a lighted greenhouse.

Some things to consider
1. LED output per watt is about 1.5-2x that of HPS/MH. So if two 300W LED's are needed to replace one 400W HPS, you got some shitty LED's
2. Output per watt will suck any time fans are needed to cool LED panels/drivers. These have fans
3. These lights are 8"x15" in area - size of a legal tablet Now look at how the LEDs are recessed around the edge of the fixture - no way light can spray many photons outside the fixture's footprint. So you have to raise the light way up to get light spraying outside that 15"x8" area. Overlay the inverse square law of light and the answer = not much photonic energy is gonna hit the plant

You get what you pay for. Sadly, it's this kind of crap product that has given LED lighting a bad name.

That is truly how you should feel as the LED market is the wild west. The lighting companies of the world are the ones that will eventually dial this in and many are there or close. Philips, GE, Cooper, Hubbell, Acuity (Lithonia), Cree, etc. There may be some greenhouse specific guys that come out of this, but in the meantime every tom, dick, and harry (or Chen, Wo, and Huang ) is creating their own LED fixture.

Thanks guys for saving me from buying junk

[Bobby Stainless]

Gettin frosty.




Next round is all GG#4...

First pic? Wow incredible.

[Bobby Stainless]

Thanks!

They hit day 29 today. Almost halfway.

[TBS]

BD - Are you vegging the GGs under an LED?

[Bobby Stainless]

nope. Thats a T5 array, and some are under a 1K MH.

[Game Over]

Oh man nice! I gotta get on the horse and get a tent.

[bgrayvy]

55% ?!?

That's what the label says. It's really a little much for all-day sipping.

[TBS]

55% ?!?

I know. Legalization was supposed to improve quality in CO

Here's what we get in Central OR for $20/gram

[Bobby Stainless]

[bgrayvy]

Not if you happen to find yourself at Disneyland, then you'll want to sip an 80%'er to help calm the chaos. 3days3carts was correct dose for touring magic kingdom with the other tarts.


stupid fucking awesome what your producing Bobby Stainless!

Been there, done that. Added a whole new level to Space Mountain and the hotel/elevator drop thing.

[Bobby Stainless]

I like fat chicks.
day 31

[TBS]

^^^Me too, especially after a month when they get moist and start giving off a stank!
