hmm. thats an awful big room for only 300 CFM. you probably have a volume of about 640 cubic feet right? lets say that 300 is brought down to 200 b/c of the filter, and down another 50 b/c of the ducting. so thats around 150 true cfm that the fan is pulling. im to stoned and lazy to do the math...
it mainly depends on the amount of pressure that fan can handle. in general though, 300 cfm isnt very strong, especially if you are running a filter through there. how man cubic feet is your room? id say keep the ducting under 10 feet with minimal bends for best results.
thats exactly what i thought the problem was like 10 days ago! i started to notice yellowing, so i started adding high N ferts, and iv been using the high N ferts almost every watering now...so i think iv overdone it just a little bit...im just going to water with plain RO water for a few weeks...
yea, i think it might be over-ferting. i will do a nice flush today. only one plant is badly affected, with about 50% of leaf mass starting to show symptoms. the other ones have just a few leaves. should i flush all of them?
here are some pics of the plants...
they used to look a lot better...
hello all. iv noticed a pattern of systematic yellowing and dying off of fan leaves, starting at the lower levels and climbing upwards. its not like anything iv ever seen before. the leaves are spotted with "death", meaning it has dead patches all over. the stems are a deep purple, and the...
hmm. now we just need to figure out where to get human bones...anybody wanna donate??:twisted:
i wonder if it was only human bones they used...or if it was entire human carcasses that they just let rot in the soil...its pretty crazy that even with some of todays amazingly advanced scientific...
holy cow! i was just doing a bunch of reading on that stuff! the amazing self regenerating soil huh? i looked for days for a website or company to buy it from, but found nothing. i had no idea there was a recipe available? is it the actual way it used to be made, or just something similar? do...
opps. i meant 1.5 to 2.5 zips...i just smoke a fat bowl...;)
yea, i definitely think its at least two.
so are you keeping what lights and stain a secret??
Deesbarrett, have you ever pondered on why you only need one drop per gallon for that nasty stuff? thats the thing that scares me about it...its like damn, what do they put in there that its so concentrated and powerful? stuff almost seems radioactive!
