Ok might be a problem might not be, but with some of the numbers online I have seen it bothers me, the last harvest, had some nits and a little PM so I read how to wash, and wash I did, let it dry and the buds all of a sudden seemed a bit airy, well I continued to harvest and placed in jars, looking at some reasons I went through the whole gambit, they were done ( I mean trich done! and all the signs a week and a half early) I chalked it up to the possibility they were clones and started faster and finished quicker, I checked the distance on the new plants I just put in, I keep a continual grow, I keep them 16 inchs away from the bulbs, I have 2 600 watt HPS, I used a lux meter and at canopy level it registered right at 38000- I thought that to be a little low, so I changed the bulb out on one of them and it never increased,the room isnt really large and I have had some that the buds were really tight, cured well and had great bag appeal, but looking around some say the HPS should be at 60-75000 Lux, hell I just dont want to go through this again, I use a combo of nutes FF- Big Bud, Grow Big,Tiger Bloom and Open seseme, Beastie Bloomz,and Cha Ching, Cal-Mag,Molasses, and usually Happy Frog. I know some strains are notorious for airy bud, but I dont think this is one- Ive grown it before and tight as a drum. Im wondering if the washing might have "fluffed" them up a tad, with 2 600 watt HPS shouldnt be a problem room is 5 foot by 7 foot, and a bit of that is just used for access, I cannot understand the low Lux readings? Or are they good? At a loss...
