Trichomes & Harvesting

Thank you for the response. To further polish up my practices, what do you recommend for drying time (temps, rh, length in days?) I have a climate controlled drying room this time around. Last time I dried in my garage (california early spring) temps were fluctuating, couldnt say for certain what the temps were. It took about 7 days for the stems to snap. I did trim wet. Cured in 1/2 gallon mason jars, which this time will be 1 qt jars. Burping several times a day (in the garage once again)for the first two weeks, ill be curing in the climate controlled room this time as well. I also picked up a caliber IV hydro meter to make sure my min and maxs are regulated. I got about 2 wks left for some awesome smelling: royal highness, strawberry dlite, and double bubbleberry. I also flushed for a week with pure ro water 0 ppm that probably messed it up as well. After reading this i wont be flushing anymore either. Last question is what is your ppm the last two weeks, recipe and why you use those nutrients. Sorry i wrote a mini novel here, but hopefully this clears up a few important details for everyone. Thanks in advace for your wisdom.
There are a lot of good threads on this subject so I won't go into too much detail, I believe this sub-forum has a nice sticky about this very subject as well.

Near optimal ranges:
Temp range: 16 degrees celcius - 23 degrees celcius
RH: 45% - 65% (the higher, the longer the dry will take)
Days: It's different for every setup due to all the variables but generally ~6 days
One of the most overlooked factors is air flow, be sure to keep a proper and continuous air flow or you will wind up with stale, crappy or even moldy weed.

You don't want the stems to snap, you want them to still be able to bend without snapping, sounds like you dried out your weed too much.
How long did you burp the jars for when your burped?
Did you move the buds around in the jars (cycling)?

Flushing isn't going to ruin your harvest but it would definitely have impacted your end product and the overall productivity of your plants.

Regarding your last questions it's very hard to give a generalized answer, because everything is relative, to the environment, your setup, your plants etc. there are just too many variables.

But I would say for late harvest I generally stay within Hanna 1000ppm - 1600ppm (depending on the strain and the variables).
That's around 2.0 EC - 3.2 EC.
I use some pretty basic GHE hydro nutrients, regular ratio, no special stuff (bloom buddy, extra bloom, whatever else these marketing people call their shite).

Nutrients are nutrients, whether they are organic, hydro or whatever other variant you find, obviously you want to match soil nutrients with soil mediums and hydro nutrients with water based mediums but other than that it's mostly nitpicking and superstition/assumptions, don't believe the overhyped marketing machines.

I burped ten to 15 mins 3 times a day for the first week in 1/2 gallon mason jars. I think those jars are to big because it held alot of moisture in between burps. I bought a caliber IV to monitor rh within the jars better. I found a thread on cure zone rh and what to do t keep it there. (65%). Thanks again

I don't pre-harvest flush my plants at all. I see no reason to do it.
I rarely flush, and only do so if I have problems with salt buildup, nutrient levels or the like (which happens very rarely in my current hydro setup).

Love this. If true it makes scheduling harvest sooo much easier.

RE: Drying….


Okay, first of all, I've only got one plant in my tent and she's almost ready to harvest. My plan is to chop her and then hang her up in the same tent and use the inline fan to keep the air flowing through the tent -without having anything blowing directly on the plant…In other words, the inline fan is pulling air out of the tent and fresh air is being drawn in through the vent flaps. I can increase/decrease the amount of airflow via my Variac switch.

My question is: "HOW MUCH air movement is necessary to dry the plants slowly?" I don't want them to dry out too fast, but I don't want them to get moldy from drying too slowly, either! Is there some kind of tip anyone can give as to how much air movement? Thanks

I put mine after trim upside down in my tent/room and after the second day just had no fans running but kept a humidity gauge in with them and watched carefully. But I live in a dry state, unless it's raining it's pretty dry up here.

Hello! These are my flowers in 74 days of flowering ready to harvest? I want maximum potency of high ?

First time grower and my unknown strain is about 6 weeks into flowering. I'm having a hard time determining trichome color with the standard 60-100x lighted microscope I hear most people use. It's very hard to get a good view with such a small viewing port and keeping the plant still while looking/focusing is even harder. I'm basically trying to find out if there's a technique people use with these microscopes or of I just need more practice. I have a loupe too but they don't magnify enough.

You are at the beginning of the harvest window. Maybe another 2-3 wks. Wait till about 30 percent amber on the buds. I dont see any amber on the pics you took. You have minimal pistils receding, and your leaves are at the beginning of the end of its lifecycle (fall). My opinion wait 2 or 3 weeks. Looks great. Keep an eye on you humidity (below 55). You will suffer from but rot if not kept in check. Peace.

I cut a piece of bud and put it in the microscope stand but not all scopes come with stands.

Thanks guys!
Hi guys, the pictures were taken of microscope 45x.
These are pictures of trichomes daylight.
I think it's almost ready, will keep 5 days, what do you think?
What levels you would specified in clear,milky,amber in %

Is it completely OK to harvest plants sections at a time? The top Cola's look like they are ready but not the bottoms. Also, I only started flushing 6 days ago. I'm stuck in a spot where I don't think I've been flushing long enough (2 weeks) but it seems like the buds are ready (amber and cloudy trichomes). So am I stuck either dealing with harsh smoke if I harvest now or depleted thc if I wait for the flushing to be done?

flushing is BS, harsh taste is from sugars being left in the plant when not dried and cured properly. You actually cause more problems and cut the plant off from the food it needs at the most important time. And yes, you can harvest it in sections.
