Just testing out the Penetrator XB300. Figured I would divide up all the plants I had and throw them into flower in a week and see what happens. The two jelly pie plants in the 5-gallon buckets are female, The clones I took are for breeding and will remain on my veg shelf until I see what Pheno's they are. I have a Fat Dick in both tents and are Fems. Everything else needs to be sorted out. Looking for a male WLD for my next round of breeding. Everything I flower is for personal use.
Your 260 is the same as mine board-wise, but I have the XW where they are side by side instead of end to end. I replaced it with the XB200 in my 3x3, so I'll be interested to see the comparison.
The XB200 is supposed to be 205-210w, did you do any watt-meter stuff with them? It seems the XB model numbers accurately represent wattage. Not sure on the Horticulture Lighting Group's because I don't have a meter.
I have the spaces dialed in and all the males taken out. I have divided up the plants once again so that both tents have similar plants. Each space has a Jelly Pie, Fat Dick, White Larry Dragon, and 4th Gear
