you'll be fine. you just simulated early autumn.

looks like completely normal growth for that amount of time.

your babies are a little stretched from being too far away from your lights. if you are using fluorescents of any kind you should keep the bulbs within a couple of inches of the plant.

count up the lumens of all of your lights. optimal light for weed is 7,000 to 10,000 lumens per square foot of growing area.

sorry for old english, but the rule of thumb is one gallon of pot for each foot the plant is expected to be at harvest.

we can't tell a male without a close-up. but it's safe to wait a couple of days for the male to show. there is really no mistaking a male when it shows.

colas form behind all growth tips of the plant. there are other buds on the same branch that are closer to the main stem/ground and aren't part of the cola. males and females are easy to tell apart - females have white hairs growing out of their buds while males have multiple pollen sacks that...

best you can probably do is wash down everything in sight before you turn the fans on, not that i think that's going to help a whole lot as the pollen is largely airborne. if you happen to have an ionic breeze or hepa air filtering equipment you can remove a lot of the pollen from the air.

how can we resist not making fun of that cute lamp hanging upside down. really. as thizz says, you want an intake hole without fan on the bottom and an exhaust hole with fan on the top.

how would we know? i can tell you that you have a 75% chance of getting at least 6 females if you used regular seeds.

yes, you want to separate them and transplant into their own containers. but before you do i suggest you do some reading on this site. there's lot of useful info on growing in the stickies of each forum. if you want to make this more than a hobby you need to study some.

well, basically because they suck in every way imaginable. they give off too much heat compared to other lights. they give off less light compared to other lights. they give off a less useful spectrum of light compared to other lights.

as promised, took the time to review and respond to your points. still think you're wrong, but i'm running out of energy on this one so i'm only going to take one more shot at it. Not trying to make you look wrong, you really are wrong. Real world example – it gets well above 100 degrees...

big sigh. i am way too comfortable to even read this right now. i'll try to get to it tomorrow. you still seem to take this so personally. i haven't called you anything or implied in any way that you were anything other than someone who is clearly highly educated and sincere in his positions...

great questions. what matters with grow lighting is both its intensity in lumens per square foot and over how many square feet it can produce that intensity. for instance your 400 watt light at 55000 lumens gives you good intensity of 5500 lumens per square foot for 9 square feet at 18" from...

called out? ok, up for the task. to get to the heart of where we disagree: depends on the air temp. if the air is too hot the convective heating will be greater than the evaporative cooling. gotta say this is wrong as stated. if the air is wet and relatively hot, there is no cooling of the...

males often show first so maybe you're in luck with the last two. not unusual at all to take a couple of weeks after 12/12 starts to show sex.

looking really good, newbie. one trick - place your smaller plants on a platform so that the tops of all of your plants are at the same height. your shorter plants will thank you with a lot better growth. also, it looked like you wanted comments so i went ahead but the general rule here is...

easiest thing to do is to put something under your inner pot to get it a couple of inches above your catch area. that way you keep a clean grow area and still keep the roots out of standing water.

won't work unless you vent out the hot air coming from the condensers. an a/c produces more heat than the cooling it provides and if you don't vent the heat away you are just running an inefficient heater.
