On Saturday, I was given a budget 600-watt LED grow lamp from a friend, but I couldn't find much info about it online, such as PAR values, how many watts from the wall, etc. All the product info said was "full spectrum" and "Double Chips 10W (2pcs 5w chips in every led) LEDs, which is (sic) much brighter and efficient than 3W and 5W LEDs."
While I realize that a cell phone's lux app isn't going to give a reliable value for a full-spectrum LED, I thought it would be good enough to compare against the 300-watt LED lamp hanging in the flowering tent. So I took the plants out, set the phone on the tent floor, and took the reading for both the 300-watt and 600-watt: 9000 and 5600, respectively. How strange. Then I ordered a Kill A Watt meter because I just had to know. The wattage these lamps draw from the wall are: 131 and 65, respectively. Conclusion: this "600-watt" LED is good for supplemental lighting, but hardly enough to power a plant like cannabis!
I should receive two 40-watt CFLs today and can hang those in the flower tent to bring the light up to 211 watts' worth, a little more than the 175 needed for 5 sq ft.
The good news is that my 180-watt light draws 108-113 watts, which is above the minimum required for the 4-sq-ft veg tent. I'd like to put the 300-watt in there if I could afford a more powerful lamp to replace it in the flower tent, but I need to get a job first.

She is doing well! She's looking a lot healthier than she did in veg. I hope she's done stretching though. I had to raise the light and put the C99 on a box to get her closer.
On 27 Jan, she got 80 oz plain tap water.
IN: pH=7.11 PPM=93
OUT: pH=6.69 PPM=2692
Painkiller XL, age 17 days
She's looking fine! I plan to let her 4th node grow in a bit more, until the 5th starts up, then top her above the third. My plan right now is to "mainline" her to get 8 tops/colas, but I might change my mind and do a mini-flux instead.
Dance World Clone, age 16 days
She's still alive. That's about all I have for good news. I cut off her dead top in the hopes her top nodes would flourish. Also trimmed away the lowest nodes to direct her energy to the two new tops. She's living under a humidity dome (aka clear 2-liter soda bottle), but that might be too little too late.
