Amazing!.. Very inspiring also. However I have to ask, why are these not suitable for plants? Surely they would be if you buy different LEDs? Some further information on this would be handy Steve.. Thanks
to answer your question deadly, plants need a certain Wattage and a certain Temp in K in order to grow, now standard LED from say a Xmas tree are typically 0.1 to 0.3w and have a K value that will be useless to plants enough for light but useless on plants now the W on steve's LED's are 3w that is sufficient given enough of them to provide the power and have a correct K value sorry i do now know much info apart from that, you can usually tell by how there made and how cheap they are tbh yes you can get LED's for like £15 but again they are no good for plants, in order to get plants they need the correct values because this requires more effort i think on the company the value increases in some cases by 5 to 10x the amount
hope this has helped a little, i am learning LED and this new temp or K value that i not know about until a few days ago myself haha, im sure steve will tell you correctly if you PM or post a thread up
