Every kind of hood has it's place. It's all about finding what works in the area you're growing in. I have a perfectly square tent, so I went with a 26in x 26in hood, only makes sense. If my space wasn't as deep I would run a cool tube or something similar. I always thought that running 3 tubes right next to each other with 400W hps on the outside and a 250-400W MH in the middle to have a better spectrum would be pretty cool. The blue O.G. sure has stretched in the last couple of days, and is looking fine after my dumb @$$ over watered her somehow. I drilled a ton of holes in the side of the buckets I readied for the B.O.G. and the Sour Blueberry, so I thought when I watered the plants there would be run-off easily. It just didn't have any run-off, and the plant acted like I drowned her in a river or something. I'm exaggerating a little but I haven't done that in a very long time is all. I know the B.O.G. is more sativa dom than I first thought and they will react to a heavy watering faster than some more indica dom ladies, but it kind of freaked me out some. It makes me a little leary about putting the S.B. in the bucket as if there's a problem with a weird suction problem, but with all the d@mn holes how could there be suction, IDK. Anyways, now that I have a better hood it's time to get to work and fill that tent up with some FEMALES, and get some meds people. I have one more girl ready right now to flip being the prior mentioned girl. That brings the count to 5 right now with maybe room for a little lady on a corner or something, we'll see. I have ALOT better coverage and penetration with this hood so I'm not worried about a little crowding, there's plenty of light to go around. I used to have to leave the glass out of the hood for better cooling for some reason, but now my tent is running 1 degree cooler with the fan running on a lower speed. I might leave the hood hinged open at night to more efficiently pull humidity off the canopy though. I also have that goofy pair of panty hose to help keep the hood clean, and I know that impedes the fan some, but it's still running happy. I know by opening the hood at night it will pull in some grime, but cleaning it a little more often is better than dealing with mold issues later. Mainly it's a battle to keep the glass clean for best lumen output. I find the cloths that you get to clean glasses with and the cleaner they sell with it is better than windex and such. You can get that stuff cheaply at wally world. Well it's off to be be a GANJA FARMER everybody, time to put in work as they say. Peace and Love.
