Sure, it is possible most LEDs produce UV light, question is what kind of UV light and how strong. LEDs are monochromatic, almost single frequency (wave) devices. Unless they are specifically UV LED chips, all others are devices using phosphorus coating to turn LED light into multi-light wave devices. The UV light from these LEDs are very weak. As someone has said, for your eyes to be damaged, you will need to tape the LED to your eyeball. dcarch

There is no need to wear eye protection. LEDs produce no harmful rays. I sometimes wear sunglasses mostly because the glare from the brightness. I was lucky. A guy on eBay was selling those used huge heatsinks. I was searching on ebay and Amazon for a long time. dcarch

The Sun Will Come Out, Tomorrow Today, Everyday, ---- Just flip a switch. It has become easy to build your own high power LED grow light. COB 110vac LEDs are not expensive. No more need to have complicated power drivers.. I made 4 COB LED grown lights, each with two 150 Watt chips. Cooling fans and heat sinks and switches. Plus Acrylic rods for focusing. 1,200 Watts of light. So incredibly bright. It's like having my own sun! With only one light turned on No, nothing medicinal or recreational. dcarch

Unfortunately my friends will treat me differently if I wear panty hose. So instead, I do this: dcarch

Thank you! I like skate a lot. It is a mild tasting fish. I think the texture feels like crab meat. It is important to prepare skate properly. The skin needs to be removed, or it will taste like someone did a #1 on it. Sous vide is a good way to cook fish to avoid over cooking. This one was SV at 135F for 40 minutes. dcarch

Cheapskate Valentine's Day dish Skate was on sale. SV skate and shrimps dcarch

Try not to drink too much liquid during the game. There is a serious world environmental problem during Super Bowl. The entire world flushing toilets at the exact same time during half time!!! dcarch

Cheap indoor long lasting, good looking stakes, for starting indoor climbers: BBQ bamboo sticks come in 36" long, a few dollars for 100 sticks. dcarch

If you use a pressure cooker, and if you find a way to adjust the regulator weight, I think you can have very stable and accurate temperature control from 212F to 250F, possibly to within one degree. dcarch

Last year's. dcarch

You can find PIDs which can take over 1000F. Try ebay also. dcarch

"Accurate" may not be the total temperature control personality of a cooking appliance. You probably would also need to know the temperature control range. For instance, your oven may be very accurate to keep temperature from 200F to 250F. dcarch

May be you are talking about mercury vapor lights. If the outer glass is broken, the bulb inside will send out harmful UV rays. LED chips can only generate one single frequency (color) of light. Actually there are no white LEDs. White is generated by using phosphors or using three color LEDs in combination. dcarch

By the time I finish making my 4 LED lights, I will have a total of 300W x 4 = 1,200 watts of light. Looking forward to nice seedlings for the coming season. dcarch

My favorite - Ananas Noire dcarch

I will. Not for a while. I am busy building a few high power (300 watts each) COB LED grow lights. Got to get them done soon to start seeds. dcarch

Yeah. I have improved my system. dcarch

I don't buy seeds on eBay. Too many fake seeds. dcarch

Here is an ultrasonic humidifier I made for my hot/cold smoker. The noise you are hearing is from another machine running in the background. Remember, you can't hear ultra sound. :-) The water looks like it's boiling, but it's actually ice cold. dcarch

I will be in that area in the next few weeks. Will give it a try. Re-balanced your picture's color. dcarch

The chef screwed up the spinach recipe. dcarch
