Wanna Ask The Old Farts A Question?
- Thread starter HempKat
- Start date
I do sativa in hydro, foxtailing happens to my plants when the temps climb into the 90's for days at a time. I have a hermie strain and thought it resulted from that. Hmmm.
Buds come out less dense when I let it go on untreated, keeping the temps in the 80's reduces the effect.

I recently officially turned into an old fart (60).. So... can I start answering questions!?

That's good news, if you don't mind please let her know she's in my thoughts and prayers and that I'm rooting for her to win this battle.

Actually by our standards here you've been an old fart for 20 years now (old fart = O.F. = Over Forty).
Anyway yeah if you feel you're ready willing and able to answer questions feel free to jump in. The more the merrier or so they say.

EDIT:
I just fixed a typo, I first wrote that Rubisco activase is hindered when canopy temps exceed just over 92'F, but that's wrong. The correct temp is just above 89'F. So, make sure not to let canopy temp exceed 89'F

Hi hempkat
now i can really use some good advise. The plants I asked you about last time, the foxtailing ones. are now in week 12 of flower, the final week. they are arjans haze nr. one or two. i have feed them full strengt fertilizer til now. and they show no, or almost no yellowing on the leafs.
I use tropfblumats, and have no drain in my grow room. do you have any idea how i can exspres flush out all the nuts from the plants?
i know its a tallorder, but maybe you have a ace up youre sleve that you can chare.
thank you in advanse
Edit
I now give them only tap water, I live in the mountains and the tap water is very clean, but a tad hard. whit a ph. 7.2-3. normaly.
is it better to add a bit of fertilizer, or none at all?

Well first of all the flushing at the end of flower should not be like the flushing one does to brake a ph imbalance or over fertilized situation where you dump large amounts of water thru the plant in a short period of time. Flushing at the end of flower should really just be giving the plants nothing but plain water for a week or two. Now I'm not familiar with the watering system you use so I don't know how that plays into it all. I'm guessing you're impatient though because otherwise you wouldn't be looking for an express way to do things. From the way you describe them (week 12 with no yellowing) they sound like they could easily go another week or two with just plain water. The flowering times associated with strains aren't hard fast rules and it's been my experience most 12 week strains can easily handle going 14 weeks if need be. When they say a strain takes 8 weeks or 12 weeks, etc. that's usually just a reccomendation.
Now another thing to consider is just how badly do you really need it flushed? Many people, especially younger growers do the flushing just because that's how they were taught or that's what they've heard others say you should do but often they've never even tried smoking an unflushed harvest to see if it really bothers them. Really and truely the only time flushing should be needed is if one has been using chemical nutrients and has been feeding on the heavy side trying to force the plants to get bigger (which really doesn't work). If however one has been feeding organic nutes then really there should be no need for a flush. Organic nutes mimic what is found in nature and when a plant grows in the wild there's nothing going on near harvest time that suddenly removes nutrients from the soil. Flushing in my opion is really more for the chemical stuff because it's similar to nature but it's not the same and too much of it can do things to your bud like make it burn poorly and smoke harsh ending up as something more like charcoal in your bowl rather then nice white or grey ash.
If I was you, ideally I'd just let it go another week or two giving nothing but plain water. If that's not possible then I'd not worry about the flush unless I was feeding it heavily with chemical nutes. Still even if you were, there's nothing I can think of that could be done in an express fashion and not having a drain is kind of irrelevent. Mentioning that I get the impression you were expecting to hear me or someone else tell you to just dump alot of water thru the soil or whatever the medium you're using. That's great for removing excess nutrients in the soil or medium but the flushing before harvest is really an attempt to remove excess nutrients from the plant. The only real way to do that is to force the plant to use up those nutes by not giving it anymore food. Excess nutrients are stored in the plants leaves but if you continuously feed the plant more then enough food it'll never have reason to use up what's stored. That's why the leaves haven't yellowed. The yellowing is what happens as the plant uses up what's stored in the leaves.
Giving them just water is the right thing to do but if it's 7.2 I'd at least add ph down to get it down to somwhere around 6.3-6.5
Yeah I get the same thing, where I live I have well water that's probably about like what you get. It typically starts out at 6.5 but drifts up to about 7 - 7.2 after a day or so if left as is.
Well the way I judge it isn't necessarily the "official" way to judge it but to me it makes sense based on how I do things and seems to work fine for me as far as giving me the results I want. Now when I say "based on how I do things" what I mean by that is that I like to do a really close trim and remove as much leaf as possible. So I figure that it really doesn't make much sense to judge by parts of the plant I won't be smoking. Although I do ultimately smoke the resin on the leaves I trim off. Anyway since it's the bud I'm harvesting then it makes sense to me I should judge trichomes on the bud itself. I also figure that the leaves are more exposed to the environment and therefore the trichomes can be affected more on the leaves by things other then normal rippening then the trichomes on the bud directly.
Also I don't use a microscope even though I did once buy one of those pocket microscopes for that purpose. What I do is use a 30X jewlers loupe when I just want to get a quick read but when I really want to judge it I take macro shots with a 4 Megapixel digital camera from .5" away and this shows me much more and in much better detail then I ever got with a scope or 30x Loupe.
Perfect^^^^ I was also taught to check in the middle of my gurl, not the top...you do great work here Hempcat.. imho..pal

Hey y'all.
I have a question about flowering. I've just been burglarized and they hacked up and stole several of my plants Fucker even came back two nights in a row and almost got caught last night. I have moved the remaining plants inside and what remains of the butchered plants, but now I'm concerned about light and I have no experience whatsoever with indoor growing.
My apartment gets quite a bit of natural light, but it's all indirect. The plants are quite big; two are about 12 feet tall, and likely have several more weeks to flower (I don't time this or anything; I look at them and sample and judge that way). Should I get some kind of light for them? I can't be moving them in and out and in and out every day. Is it possible they'll finish off fine indoors with less light?

At 12 feet tall they'll finish off indoors but they won't finish off fine without additional light. Unfortunately at that size you would need substantial lighting, probably more then you would be comfortable with running. Additionally you would need more then just lighting because you would need several 600 - 1000W HIDs which each generate quite a bit of heat. So you would need fans for cooling, ventilation and air circulation. You would also likely need a way to control humidity.
Given the size of your plants and the point they're at in flower you'd be better off bringing them in and out each day even though that would be a major hassle.

Thanks, man. For the moment I've got them on a rotation--I'm bringing 4-5 out to spend the day outside every day and then back in. I might get some motion detectors, but the cops pointed out how easy it is for them to scramble up the wall and onto my terrace since all the rooftops are communicated and it feels somewhat futile.
It makes me so angry, and what makes me angriest is what fools they are. I know my plants and have raised them since March; they come up here and butcher them, and what the assholes have is essentially going to be shake plus the plant I had heavily inseminated, which was just about ready to go but was fully seeded.
Any idea what the minimum light they need to finish fine is? They all seem ok for the moment after this week of ins and outs.

It's difficult to say what a minimum amount of light needed would be. Essentially it boils down to the amount of space that needs to be covered and a law of physics called the inverse squared law which says that light energy is reduced by a factor of 4 every time you double the distance from the source. So what that means is that whatever the amount of light energy (PAR) is at lets say one foot from the bulb will be 4 times less at two feet 16 times less at 4 feet 64 times less at 8 feet. This same rule or law even applies to the sun. The difference however is that the light from the sun has already travelled so far that it's essentially going to have the same strength at whatever the height a plant is. On the other hand the light from something like a 1000W HID starts to become useless after about 5 feet.
I'm not sure what you mean by how much light loss can you expect. I assume those dimensions you gave are in inches and if so you're talking a box slightly bigger then a desktop computer with 300W of light. There isn't enough room for there to be much light loss because the farthest it can travel in that size space is 2 feet. I'd be more worried about heat from two 150W HIDs in that space then I would be about light loss.
