hello world, I am the Plant Armbasic..

please support & share our mission;



I help plants grow in dark places - no sun needed. I can easily be attached to any existing plant pot and provide light to the plant. Do you work in a windowless office space, or maybe your house doesn't get any direct sunlight - no problem, the plant arm is here to help..


the 3rd picture shows my planned wireless package upgrade (the plant arm pro). with this upgrade, the plant arm will be able to keep a picture log of the plants growth since seedling stage, turning it into an online time-lapse video, so the user can watch the over time growth anytime/anywhere. the user will also be able to turn on the camera and check up on his/her plant via any internet capable mobile device.


below is a video of the plant arm pro being used together with the plant doctor (an earlier clay model). they easily can be attach and used together, giving the user a better overall control over their plant's health. the plant arm is also compatible with the plant pot.



let's build..>

Step 1: Frame

my body is made out of perforated metal hanger. this metal can easily be bent by hand to adjust to the new size requirements of the plant.


an upside down U shape can be given where I connect to the plant pot, this way the user can easily slide me in/out from the pot.


the LED lights are secured to a 16 gauge galvanized nail stopper. this thick yet very light steel acts as a passive coolant for the lights.


everything is secured together with 2 nuts & bolts. 1 at the base where I connect to the pot and 1 up top to secure the light bar.

Step 2: Electrical

I am equipped with;

4x 1W high power LEDs (2x warm white, 2x cool white)

1x on/off switch

1x LED driver

1x AC cable


apply a little amount of metal epoxy under each led and secure them to the flat bar.

now connect the LEDs all in series.

connect the - negative wire straight to the LED driver

connect the + positive wire to the outer leg of the toggle switch

connect the middle leg of the toggle switch to the LED driver

connect the other end of the led driver to the AC cable.


my planned upgrades are;

3x 3W high power LEDs yielding 9W of energy - using the same amount of space

webcam module

wifi module

Step 3: Conclusion

I am planned to get a 3D printed cover upgrade for the frame and hide all the wires better. I am also planned to get a rechargeable battery/solar skin upgrade to be more mobile.

    hello GG, I have been successfully growing plants with high power LEDs for over 4 months now. these are the best light sources I have yet to use, the plants love them. you could use 430/660nm spectrum lights as well but cool/warm white give a more natural light and do the same job just like it would be 2700/5000+ Kelvin with CFL bulbs. check out my other plant care instruments to see more successful examples. the first picture below is 3 tropical lychee trees grown using 11x 1W HP LEDs, the 3 of them are sharing this source so actually getting ~3.5W each.. second picture is the same citrus tree that you saw in this post, but with a 10W plant arm attached to it. 3rd picture is one of the lychee trees in an earlier stage, this one is under 16x 1W HP LEDs, here I chose to use 4 different spectrum lights. thank you for your interest, give it a try if you can - there is nothing like it !


    Hi Akin , do you manage to make the OV7670 camera module ? if so , can you make an Instructable ? there is not much information on the matter , cheers from Argentina ! .

    hello udubinsky.. i have been successfully growing plants using only warm/cool white led combinations. plants are happy, they don't show any signs of stress of deficiency. but if you would like to add more colors in, check this out;

    you can easily add in 660nm 430nm and many more (what ever ebay has to offer)

    thank you for your interest !!

    Hi Akin, Im definetly going to try this, as winter is approaching Im going to have to move some of my peppers inside, so this is going to be extremly helpful to supplement the natural light in the afternoons.

    make sure to keep me posted..! you should also check out my indoor tomato grower post, in my case I have tomatoes, but peppers will also be perfect. you can do a combination of LEDs and CFLs if you want too as boosters.
