congrats on your harvest! now, hit us with the smoke reports!
I must take some pictures of the dried buds to post them among the smoke report, after a few days of curing on the jars (for a more 'compact' look). But seriously, I think I will have serious trouble trying to make a smoke report for AK47. Two or three hits could be more than enough for this purpose, as a 0.5g joint will totally blow up my mind.
I can't describe the taste of the AK47 - the first hit is something chemical, sometimes it remembers me of the taste of perfume or cologne - partially bitter, but very intense. The second hit make my lungs explode and the third one usually send me in another dimension where real world has no sense
Anyway, the AK47 buds looks amazing : the buds have shrunk after drying, and they are almost white in color. I must remember to take some macro shots. If the strong odor of this strain would not be a such major problem, I would grow this strain again indoor, but it was a PITA to cover/control the stink . What does really surprise me is the fact the dried buds do not smell so strong.
Please keep us posted on your white LED experiment. Great job!
hello hempfield in post # 255 of Building a home made led, you said mounting your panel. I'm putting one in the same way. 3w leds are, and have a source 24V 15A, I will use the current limiter as you showed. In his panel were 11 strings of leds. 11 current limiters were used? Connection of switches on / off was taken if you can explain? Sorry if the question seems silly but that part is not quite understood. Thanks for sharing your knowledge and experience, peace! I did this same question in thread building a home made led.
I thank you already!
For the beginning I will go with a less effective current limiter circuit, which use a MOSFET transistor as variable resistor, controlled by a feedback loop composed from a load resistor and a NPN transistor. There will be two strings of 3 LEDs, powered by a 12V power source. The circuit will be built right on the base of the heatsink, without any PCB, for simplicity.
This will be the 'poor man' version.
If the results of the grow will reach the expectations , I will change the current limiter with a switching driver, based on a LM257 (http://www.ti.com/lit/ds/symlink/lm2576.pdf) and I will try to build it with PWM support, for dimming (I personally don't think this is necessary for a grow light, but my intention is to create a circuit that simulates sunrise and sunset).
My final goal is to create a simple and cheap light source, compact and modular (this light is intended to cover a 1sqf area -for best results and up to 2.25sft ), easy to build and operate, especially in the case of small scale grows. If the plants will require this, a 10W multichip RED LED will be added (http://www.ebay.com/itm/High-Power-10W-Red-Led-400LM-620-640nm-Energy-Light-Lamp-/260965696179).
