They are in their fourth week from putting them into soil and they've started to develop these little funny things. I guess these are preflowers. Can we say anything about the sex? Please enlighten me:)

Not preflowers...
secondary branching... but you're looking in the right spot.. that's where you'll see preflowers eventually.. probably about 2/3 up the plant or closer to the top.
Ya, what Bob said. Just let them grow. You'll know them when you see them.
Thank you. As you both advised, I waited (switched to 12/12 also) and took a couple of photos. Here they are...
those pistols look female, :D
Peace,
Denial
Yes, definitely female from the last picture you posted. Are you completely flowering your plants now? If you moved to 12/12 just to sex, you're going to lose about a month of total grow time to re-veg it.
no, not for just sexing... I'll continue growing them in 12/12. They are not big though. A little taller than a foot. This is my first experience, I wonder how small the yeild will be...:rasta:
Now I have those two ladies and they started to smell like hell. I have installed a manually made carbon scrubber near the top of my grow cabin and it works ok.
I have an active intake at the bottom. The fans run 24/7. My question is that should I place a carbon sheet on the active intake as well? Cause the odor is not completely gone (though it's not that irritating)...
Is it possible to seal the room completely? Filtering the air coming into the room doesn't seem like it would make much difference if the odor is still able to escape the room. If it's not possible to seal the room entirely, you may eventually want to think about using an exhaust with a slightly higher cfm rating.Quote:

My bad, sorry. I explained it wrongly.
I'm using a wardrobe as a grow room. So the exhaust fan filters the air and gives it into the room again. And the intake also takes air from within the room.
In other words, there's no fresh air entering the room from outside unless the room's window is open... :D
I have sealed the closet entirely except there's no carbon stuff on the intake opening. (Is it possible that some air can flow through the intake fan to the opposite direction?)
Ah, I gotcha now. It'll be tough to clear up the smell of the room without some ionizers, or something to cover up the smell. You really need to be exhausting outdoors, or at least into an attic, to pretty much neutralize the smell from your room. But I guess it's safe to assume that if it were possible, you'd have done it by now.
Well, there's always incense... in the end you could have a bountiful harvest of patchouli & jasmine scented buds! :thumbsup:
So there's no point using a carbon scrubber on the intake fan, right? Right now the smell is not that bad (10 days of flowering). I hope it won't increase much in the following weeks.
Thank you... :thumbsup:
Well, if you have the means to put one in there, it'll probably make a small difference in the smell outside the wardrobe... but again, as long as you're venting directly into a closed room, there'll likely still be a lingering smell.Quote:

Some strains are absolutely pungent during flowering, especially towards the end. Others aren't nearly as bad. Make adjustments based on your circumstances and remember what works best, it'll make it that much easier for you next time. Take care.
@Mr. Clandestine.. thank u very much... :rasta:
I have put another carbon screen inside the closet. Now the air is being sucked in through the carbon screen and exits through another carbon screen.
I have also put a carbon screen on the active intake and sealed all the edges as much as I could. The smell is completely gone now... :thumbsup:
I also used two screens (one for intake, one for exhaust) to collect dust before it reaches the carbon filters. That way I hope them to last longer. (There was no dust filter before, and the carbon screen only lasted ten days or so)
Good deal, man... glad to hear it's working out for ya. Looks like you're starting to get just a slight bit of leaf curl on one of those plants, but aside from that, they're looking really healthy! Take care, and best of luck to ya throughout the rest of your grow.Quote:

By the way - How many watts is your HPS?
Only 70 watts...:rastasmoke:
looking good...please continue to post with pictues, i want to see how this turns out
Some pictures...15th day of flowering...
Looking nice!
Some of the very bottom leaves started dying and the end of some leaves (near top of the plant) started turning brown. What's the problem here? As far as I understand it's nuteburn or heatburn. :confused:
They are in the sixth week of flowering. Should I be worried?
Thanks in advance...
Those plants are the picture of health.
You're seeing the problem with a small HPS- the low leaves don't get a lot of light, and will eventually die off. But at week 6 with the tops looking that healthy, you are FINE. Better than fine. Yer golden.
Thanks @stinkyattic .... :)
How much time till harvest? Can we guess by looking at those pictures?
impossible to tell by those pics, but if I were to guess probably another 2-3 weeks....your pistils still look very white and fresh.
the tips will start to turn brown soon.
you also need to infest in a 30x or higher magnifier so you can look at the trich's that's the only surefire way to determine harvest time.
you're plants are looking SO sweet, don't wait on getting a magnifier!
one question...where did you buy that HPS lamp? it looks kind of small, I'm needing a small one but I can't find anything small
It's a 70w hps. I found it in an electronic store.
Question: I haven't got a 30x or better magnifier but I do have a normal microscope (up to 300x). Can I take a very small sample so that I can use the microscope? And where should I take the sample from? The pistils or the leaves?
I've thought of another way to see the trichs. I've used my digital camera to take some shots and cropped the pictures.
Can we tell by those photos?
The trichs still look pretty clear in these most recent shots. When to harvest depends on what kind of high your looking to get from them. More clear to slightly milky colored trichs will give you more of a heady high, while more cloudy to amber trichs will produce a narcotic, couch lock type high. I like to wait until about 15% of the trichs have turned amber, but will harvest a little earlier if the plant is taking forever to mature. (11th week on up...)
They are in the 7th week of flowering and almost all of the pistils are still white. About that trichome method... Where should I look? The top, middle or bottom part of the main cola? Do they all advance at the same speed?
You may have a strain that needs more than 8 weeks to finish its flowering cycle. Several of mine take 10 weeks, or sometimes longer. And when you're looking at trichomes, I'd check the top of the colas first, and then compare them to the lower buds that aren't receiving as much light. The colas themselves generally mature at the same rate, but the lower growth ("popcorn buds" - I hate that term for some reason) can take longer to mature. Since the tops sometimes do mature faster than the lower growth, so do a side-by-side analysis to determine when to harvest. And you can harvest just the tops, and leave the rest of the plant in flowering a while longer if you need to. With some of the tops and side branching removed, you're able to get more light to those areas that didn't used to have it.Quote:

Glad I could help & best of luck with your harvest! :jointsmile:
while I look at trichs in all areas, I tend not to rely on the ones on the leaves as you've showed.
the best places to look are the spots you'll be smoking :)
Update...
50th day of flowering...
How many weeks to go? And what kind of changes should I be expecting in following weeks? Any experts opinions?
They look wonderful. I see some tip scorch but nothing to be concerned about at this time. I think 2-3 weeks to go. You are starting to see some browning of the pistils. In another week and a half you will probably be ready to flush, and then start checking the trichs more closely to determine chop time. You will see a lot of additional 'bulk' between now and harvest, on top of what already is a respectable bud mass you have now.
I appreciate your help @stinkyattic. I got all the answers thanks to you. But I have another question :)
For some reasons, tomorrow I'll have to give them 20 hours of darkness. As I mentioned before, they are in the 7th week of flowering and there's not much to go. Might this 20 hours of uninterrupted darkness affect the process in a bad way that I can't undo?
P.S. They are doing just fine, and now I can see some false seed pods on the buds... :thumbsup:
Don't give them 20 hours of darkness. Give 12 or 36. Simply wait until the lights go out, unplug the light from the timer while still leaving the timer plugged in (turning), and do not plug back in until you are completely ready to go back on your original schedule. Basically, just SKIP an entire lights-on period and don't shift the schedule unless that was your intent.
I don't have an automatic timer. I was thinking that giving them 4 hours of light is better than nothing. So, I'm giving them 36 hours of darkness and then go on with 12-12 schedule. As I know, some people use that 36 hours darkness just before harvest. I have about 2 weeks more, since you said that I guess that won't matter.
I've got one more request from you @stinkyattic... :jointsmile:
Why not giving them four hours of light and instead keeping them in 36 hours of darkness? Poor things won't get any light tomorrow... :(
I'd appreciate if you explain that...
I'm a kind of guy who likes to learn... nothing more...
Thanks again...
i havnt grown since last season, but if i remember right, the dark is the time they use for maturing and "growing". were the light is the time when they get all there energy.
so if that is correct, the 4 hours might shock them.
were the 36 hours of darkness will just let them mature a littlemore.
((also, dont forget to flush a week or 2 before. you look very close to harvest )) :hippy:
The only reason I suggested the longer dark period is for convenience, assuming that you need some time to do whatever you need to do. But given the choice between a less than 12 'day' and a long 'night, I'd pick the long night. It's just instinct; I can't really explain it, but I feel that the shock would be less EXTENDING a day or night than CURTAILING it.
