Growing Plants With LED Lights

Using It

Now for the best bit, actually using it.

1.)Place the tissue paper in the small tub and dampen with water, then sprinkle a few seeds ontop and place inside your LED growing tub.

2.)tun on.

3.)wait

4.)eat delicious plants!

depending on what your growing you may need to transplant the seeds into a better growing medium once they have germinated.

During my first attempts at growing plants under LED lights, i grew cress in a bean can, and used a PIC microcontroller to turn it on and off every 12 hours, this produced failry good results, the cress grew quicker than some placed on my windowsill.
After reading around a bit on the internet (whether you agree with the use of a certain herb which is currently illegal in the uk or not, the people who grow it tend to be very knowledgeable on plant cultivation, and have a wealth of experience in growing plants under artificial lights) i found talk of keeping lights on for 24 hours during vegetative growth stages, then encouraging flowering by switching to 12 hours on and 12 hours off during, i don't know if this applies to all plants, but i shall be experimenting.

I'm still playing around with this so any suggestions/improvements are greatly appreciated, and if anybody decides to do this themselves (i hope you do, its great fun) i would love to hear about your results.

About how long did it take for your seeds to sprout?

 Might it be that these ones grew better than those on your windowsill as there were warmer due to all the electrics and being in an enclosed space? 
While i'm sure some plants / drugs might be better grown under artificial light i dare say cress can survive without external power supplies!

Interesting as an experiment though!

through my experimenting ive found a 16-8 light cycle is good to start the plants and then 12 12 to force them to flower

 For growing give them light 24 hr/day.
Darkness is not needed.
As long as lights are on they continue to grow.
I agree with flowering at 12/12.

blue for veg
red for flower
just white and u`ll b all right
plant will always grow towards the light so you could try horizontal grow tube

an idea i had was solar cell to charge battrie pack conected to photo cell which could switch a relay to turn on battrie pack when go`s dark  "any help of wireing would be helpful"
