I recently saw a instructable where user GreenThyme grew some plants with only blue and red spectrum. There was also an interesting picture:


That looks like something I would like to test out.

I'll probably use bean seeds for my experiment since I have a lot of them home and it germinates pretty fast (8 - 10 days).

I ordered a 30W 650mA LED driver that takes in 220V which is great, 10 cool white 3W LEDs and another 10 3W Grow spectrum LEDs.
I also ordered a timer switch since it would be easier to set up then an arduino + RTC + relay ...


I'll probably just solder the LEDs to the star bases I have at home from the first time I ordered these grow spectrum LEDs and then screw the bases on a piece of aluminium.

About those strawberry's I mentioned 2 weeks ago. I made a mild nutrient solution with the TNT complex, only 25% strength, and then pushed the runners in a hole in the rockwool cube. Till now, the runners have been growing roots! It just needs a week or maybe more. That isn't a problem though, since we're having nice weather here in Slovenia.

If I quit now, I will soon be back to where I started. And when I started I was desperately wishing to be where I am now.”
