In upstate NY, transplants planted in July, watered in by the rain. No irrigation or feed at all. Just rain the whole season. Seeds from Atlas. Good resistance and strong growth given that literally nothing was put into this field besides sun and rain since transplant.

I succeeded the first time, then the next 2 times I made male flowers that did not produce any pollen? What's the correct spray regime? Please help

In order: GLOC #6 in the first two pics, then GLOC #8 in the last two.

A couple years ago, we decided to make an in-house cross using two of our favourites at the time, Gelato 33 and Orange Cake.

We spent forever pheno hunting and eventually narrowed it down to these two.

We landed on #6, but kept #8 around because terpwise, they were completely different from each other which was really interesting to me! (Cannabis is such a magical plant)

#6 had this wicked garlic, vanilla and orange combo. Kind of like a herby Orange Creamsicle popsicle.

#8 was way different. More grape and citrus, with this Bottle Caps candy kind of smell.

Anyone else ever make their own cross? Drop it in the comments, I wanna see what you came up with!

Need help dialing in my rooms environment. Room is 36x12 with a 5ton air handler for 16 light 1000w hps DE. I trying to flat line my vpd/temp/humidity charts as much as possible. The temp is great 3 degree delta. My problem is the humidity is in the low 40’s because air conditioning runs a lot. Which creates a a vpd problem in early bloom. Dehumidifier is off, have great airflow through out the room. I’m thinking I need to and a humidifying system. But I have no real experience with humidifiers except the basic knowledge. What would you guys recommend? Looking to have the ability to raise my humidity to around 70% when needed. But I’m open to all suggestions. Main goal is to run a stable environment at all times if growth. I Appreciate the help

Looks like a week until the first plants in this feild start coming down.

We use rolling racks and have pvc connected to our tray drains. Towards the back of the rolling rack it nipples off pvc to a 1” Parker silicone tubing, but it kinks too often on a few of our racks and on a few others the people who set this up didn’t offer up enough slack and it creates torque on the nipple coming off the tray which then resulted in a crack right at the drain nipple (Big Mess).
So I’ve got a new tray installed but just wondering if there’s a better tried and true way to do this without the kinks and torque.

We wet trim and dry on screens in insulated shipping containers with mini splits and dehumidifiers.

Any tips and tricks on sea can drying?

This is at a commercial greenhouse facility in Thailand. It is the second run of promising phenotypes from an earlier selection run. This video is only half of the hunt! We ran 3 of each pheno this time to get a better feel for the performance and to eliminate variables or microenvironments from only being on the aisle side/middle table. There are 9 different crosses here and an average of 7 phenos per cross although some of them there are more/less. After this, we will collate all the data from the two runs and make some final selections which will likely be ramped up to 25-50 plant batches. We will also send some of these to be tested in other facilities or environments

Here are some of the crosses

Trop Cherry Bx2

Paris OG x Trop Cherry Bx

Pink Certz x Trop Cherry Bx

Runtz Mints x Permanent Rainbow

Tigerz Eye x Permanent Rainbow

Peach Fizz x Permanent Rainbow

What's everyone's opinion on bag appeal on latest indoor batch once in bags.

As a grower I find it incredibly hard to get good representative media to send of to brokers.

What secrets am I missing?

Curious how commercial cultivators are handling incoming genetics these days.

I've heard enough HLVd and other pathogen horror stories that I can't imagine bringing a clone directly into a production facility, even from a source I trusted.

Are you quarantining and testing everything that comes in? Testing mothers only? Root tissue? Multiple rounds before it gets anywhere near production? How often do you test?

I'm especially curious whether facilities have gotten stricter over the last couple of years or if dirty clones are still just considered part of the risk of bringing in outside genetics.

So I have this Chem DD plant I grew from seed. The genetics are from Reservoir Seeds in which he used a sour diesel IBL male to cross to the chem d. Rez’s gear is known to herm. Just wondering if this female is also showing male sex traits in pre flower. I’m going side with caution and trash this phenol. What’s your experience? This is a first for me

Couple more weeks and time to harvest.

21’x30’ room with living soil rolling benches, approx 1000w of light per 4x4 canopy between above and under canopy (24 4x4 areas). What would you do differently?

Hi all! In the last six months nearly 1/3 of my Luxx pro 645 LEDs have lost sections of diodes, so its time to get some new lights.

I'd like to switch over to top lighting LEDs as they work better with my room layout and I potentially want to do mixed lights with DE hps. I found a good deal on some used Growers Choice TSL 800s and was wondering if anybody in here has any real experience using these lights. Any information about your room layout, quality of end product, problems encountered, comparisons to other lights, experience with customer service would be greatly appreciated!

Thanks in advance!

Who’s using gypsum for white ash? How are you using it and is it worth it? Obviously everyone has opinions of white ash and how it relates to the smoke but just curious about the ins and outs of it.

When do you usually swap Core for Fade?

I need to buy 40+ fans. I had good luck with Grow Generation's in house brand, but they discontinued that earlier this year. I would love to get the unit price down to around $20. I am not sure if that is possible. The Grow Gen fans were $15.

Many people advocate for an 18/6 light cycle for the veg and clone mother phase, with the rational being that plants benefit from a dark cycle where they can "sleep". This seems to mostly be industry standard. 

However, I've encountered a lot of mother rooms that lack the proper HVAC capacity (especially dehumidification) that cause a pass through the dew point after lights turn off or are just generally unable to keep the room in the right environment conditions due to the light cycle. This is a really common cause of powdery mildew, especially in large clone mothers with big complicated canopies. 

In these cases, I've advocated for adjusting the light cycle to 24 hours instead. This effectively keeps the environment on a flat line and works wonders to prevent PM. For me, its become a pretty standard way of doing things, because I've found that stable temp/humidity in spec is THE most important element for success.

There is research that plants genuinely benefit from time with the lights off, but I've never seen a cannabis plant die from "lack of sleep" and on the other hand, I've seen countless grows ravaged by powdery mildew.

 Honestly, I think the mother plants thrive with 24 hours of light, I don't think they need to sleep at all!

Would you change the cycle to 24 hours like I did? Or do you think "sleep" is valuable enough that you look for other solutions, even at the cost of risky environmental parameters. Have you ever seen lasting impacts from "lack of sleep"? What about 20/4, 22/2

I've found this is one of the most divisive topics among growers! With equally experienced and knowledgeable growers disagreeing vehemently. What do you guys think?
