Ok I think I will do the same. Ive ran a boss hood with an DE Ushio 1k at that height with no issues, but wanted to try out the gavita/nanolux. The Boss hood was more like a 5x5 footprint or maybe 4x6.
I def will be giving some info once I can test my new room cause I have 9 nanolux's sitting in the box but 1 . I tested 1 in feb and since it was in my temp room and only had 8ft ( kept it on 750 w, then 1000w last week and burned a few leafs)
I must say it kicked the crap out of the previous HID's ( air cooled raptors ) and def shows the new tech is here even from a half a run when the buds are so AAA closer to the DE's
Anyways I don't grow in the summer indoors but when fall comes ............. Those 10 Nanolux's are cumining onto then roof then ;)!
