Hey all overgrowers!
Finally I’ve compiled all my photos from last grow. This was actually a test of custom tailor-made grow LED light. RainForest from General Hydroponics as grow method was failproof at the time and chosen as proven platform. This time with 6 Hash Plant (clones but originally selected mother from Sensi Seeds pack at early 00’s).
You can see same grow cabinet footprint with different combinations here:
So you can easily compare results with Osram Plantastar 600W High Pressure Sodium (HPS) to this custom 340W LED light.
This light had 3 regimes - each powering different circuit of diodes in different field
- Grow - 156W in blue Cree diodes
- Bloom - 177W in red Cree diodes
- Extra UV - 8W in ultra-violet spectrum
For vegetation period of small clones just grow part was used saving electricity costs. Once plants got bigger also red spectrum was switched on totaling 340 watts. For second half of blooming period, UV extra spectrum was turned on…
This lamp had this extra ultra-violet spectrum because it was a prototype test light.
I’m not sure if those 8 watts of ultra-violet light has done something beneficial to the plants, but I can tell you for sure that it was functioning as you could feel sick after spending few minutes nurturing plants with it on… After feeling sickness I decided to turn UV off every time before entering the room. UV is not healthy thing for living animals and definitely not healthy for human skin and eyes.
