LED Growshow

Somewhere in Amsterdam, back in 2007, I started developing a Led panel system for growing Marijuana with LED's, these webpages show you the different tests I did with just a few plants in a 60 Watt, 40 by 60 cm system. Bigger systems were designed and tested here as well. These famous Hans Panels were the very first available that can actually:

Grow Marijuana with only half the electrical power of HPS.

Please note that this site is for educational purposes only.
Growing Marijuana is prohibited in a lot of countries. Don't grow Marijuana unless you are sure it is legal to do so.

Finally, You can purchase the LED Grow panels I developed

With over 3 weeks to go, I am expecting a great result :-) Please come back for more....

Plants are looking great, there are 5 weeks to go, let's keep up the good work :-). Forgot to mention, the total power consumption is 93 watt.

Overall growth has stopped, and flowers are developing fast, it seems they are much faster than with the Red/Blue panels. The panel is switched to flowering mode, with the extra Red leds, in about 6 weeks we will know the result.



Here is a picture of the output in Flowering mode, as you can see only 6 extra Red and Deepred Led's create a big difference, closer to the optimal flowering spectrum.

Switched to 12/24 hour light cycle, flowering, a week ago. Please note the panel is still in Vegging mode, this is to make sure the plants remain short and bushy, instead of becoming rather stretched and thin.

As you can see lots of growtips are developing rapidly. I will let the plants grow for another week or so, and I will keep tying the main growtip down, to increase their number until I have about 20 that could all become big cola's.

Only 4 plants this time, so I am giving them a little low-stress-training to get more big buds.This is done with a piece of rope, tying the stem losely to the side of the pot



Here is a picture of the output in Vegging mode, the high amount of Blue light made the plants very bushy, nice indeed

July 23, 2017 Finally a brand new Set-up, thank you for your patience



Here is the new product, ready for it's final test, as you can see it has a huge heatsink and no fan, so it is totally noisefree. Besides that it has a square reflector to make sure the light is spread optimal in a square tent. The seedlings go in early august, please come back for more.



Most of the work is done by a CREE CXB3590 COB, as you probably know it has a fantastic efficiency, there are many reports on the web showing great results. In this product, the COB is assisted by CREE XPE2 led's, to give better control of the plant's shape.



For the vegging period, 4 CREE XPGDRY are activated to improve bushiness.



For the flowering period, 6 CREE XPEEPR are added to stimulate massive buds.
