Amnesia freebee
Day 18
Shes alittle small for her age,well last ph tjeck was 4,8 lol.
Light dimmed to 60w, pwm dimmer is finished, but i smoked to much of the blue automazar while doing it , so itˋs missing 2 key components to work properly. ”work in progress”.

10v pwm dimmer
Its dimming both led panels (2 led drivers / 4 cobs). So the wattage calculations is from both drivers (100% = 111w messured from wall socket).
Its accurate dowm to 60% +- of 1 watt.
Then the led drivers starts to be inefficient (acording to spec sheet)
% of dimming is linear. Mah. (amps) output from driver is also linear. (Acording to spec sheet.)
Pwm. Freq is 520hz. Im prop. Gonna bump that up a little to 1500-2500 ish hz. When i have the time to look (read) about prescale and timer libs. (prop not gonna happed ).
led driver have a mcu on the dim input. so upping the pwm freq will have no effect at all.
So at 61% dim 68w 427mah. cobs at 150is lm/w. thats not bad for old cxa2530 .
Yeah i know fish eats umols, and solar panels drinks lumens. Plants farts ppf.. and all that jazz.
Stay green
Lcd backlight off

Lcd backlight on
Ups a typo on the lcd

Day 34​

She´s in preflower stretch (maybe). No stretch under the new cob panels.
Invironment completly changed with the new light.
So might be the little difference between day and night time temps 4c .24c to 20c

Notes attiny85: pwm and delay functions is a nono. Remove delay and/Ore change prescaler :-(.

Day 38
Well im more ore less, back to my old growing schedule, so amnesia is looking steller. I borrowed a lux meter from a friend..So much easier to adjust light, than with a ruler. Donˋt really care if its accurate ore not. If plant likes 28.000 lux at canopy and dontˋt like 35.000. (Use your imagination).
Easy!!.. Right!!!. Ordered one for 15$.
She had som defoliation( top ) and some pruning( Bottom ).
I'm not completely satisfied with my pwm light dimmer (yet). And i need to get that fixed, before i start to assemble the last 2 cob panels with 1212 3000k/3500k.

Day 45
Looking healthy.
She had som defoliation (top) and some pruning( lover branches ).
Im really, really happy with the performance of these 2 cob panels, and can´t wait to get those 1212 panels build.
Delicious Critical neville haze will be my next sat.dom. strain to grow.
Attiny85 10v pwm dimmer.. Well it canˋt run a pwm signal while communicating with i2c (lcd
display). It hangs / freezes while still dimming .
So iˋll build a new one using a arduino nano. With 2 pwm signals dimming 4 cob panels.
Problem solved, Thought for a moment it was my fault.

I like that amnesia!

I don't know why more people aren't using the dutchpro nutes. They work well

Me too. it aint outgrowing my tent . I have some more sativas i whant to try out this year Seeds of life: sol haze / kabala / Nordika + some i cant remember . I used the dutchpro for a year now, 7-8 grows, only complaint is that itˋs "weak", to reach the same ppm as canna ore cyco, it takes 28-33% more nutes, on a bigger grow, its expensive. but im only using 125ml ish. pr grow.
Stay green.
