Psua, have you considered popping a few more beans? In my experience if a seedling has a hard time at the very beginning, regardless of the reason, it takes quite a while for it to recover. You might have solved whatever problem it might have been but they are still going to grow slow as fuck...

They seem to be liking the LEDs. Those two lanky seedlings were already that tall when put under the lights so I would contribute that stretch to forgetting about them in the corner of a dark room right after they emerged from the soil. Haven't seemed to stretch anymore since going under the...

I think the problem is that the camera only cares about particular spots of focus. Like you say the numbers don't need to be accurate as long as they correlate but the chances of having them correlating are very unlikely as you can get ten very very different reading by simply focusing the...

I looked into light meter apps a while ago and they all seem to be pretty bad. This is from the one linked above in their own words: "Please, note, it is impossible to measure illuminance (Lux) using a camera, do not trust anyone who says otherwise. A special device must be used for this...

CREE is currently making 10w LEDs with a single die. There are 100w and 150w high bay fixtures using those LEDs but they are pricey - ~$350 from China and likely twice that made in the US...

Small but precious. And she looks pretty happy.

What are my charges? And you forgot to read me my rights. :)

But how does the image of the apple travel through the tiny tube? I just can't imagine how it fits unless there's magic involved. Oh wait, must be a miracle.

How does someone who doesn't believe in science explain the internet... that's what always puzzles me.

Did you read the article? They are saying all mammals come from sharks - well not sharks but a type of cartilaginous fish. Actually ALL invertebrates, that's everything with a spine. So Darwin is right and the ape theory stands. And if you trace us back even further we came from a primitive...

Well in reality I drove the entire 1.5 lbs in one trip without incident. Are you guys allowed to grow for yourselves? I can't imagine getting by growing outdoors with such a small limit and actually abiding by it. Grow one tiny tiny plant, harvest half, destroy the other half, and then run...

I had to move one time and had just maxed out my holding limit of 1/2 a lb. Had to make four separate 300 mile drives to move it :( Cost me over $300 in gas. Keeping completely within the line is rough.

You can't grow outdoors there? Here In CA you can't travel with more than a few ounces and can't posses more than a half pound. But you are able to grow 6 very large outdoor plants each season and you are also allowed to donate your extras - actually it's required unless you just want to...

"Used as a soil amendment and fertilizer, Greensand (0-0-3) is mined from deposits of minerals that were originally part of the ocean floor. Contains about 3% total potash, along with iron, magnesium, silica and as many as 30 other trace minerals. May also be used to loosen heavy, clay...

I drove a couple pounds to a dispensary once... ** ^lol at that statement. I smoke a pound a year to myself. Assuming that's sarcasm :)

Sheet metal works pretty well.

Gram is a metric unit.

I want to order one of these - 16 xml's on a single board? As shown in Figure 4, this high-bay luminaire design has sixteen XLamp XM-L LEDs arranged in a closely spaced 4 x 4 rectangular array. To handle the high power density we used a special copper MCPCB from Rayben.5 As shown in Figure 3...

Ah, that makes more sense. Damn that's a large die.

Yeah but even the 10w CREEs are arrays. Here's an MC-E for instance: Four individual die.
