Celt’s 2020 Grows

The Celt said:
This will be the first grow from my GA3 seeds but I don’t expect any issues, been growing feminized seed since I started 6 years ago and they are produced with GA3 :)

Nice! This sounds like a very interesting way forward.

I had a bit of further reading on GA3 this weekend:

Many seeds from semi-woody trees and bushes need a period of cold (stratification) around 2-3 months before waking up from their hibernation and can then begin to germinate. During the cold season, gibberellin is formed naturally in the seed and when the seed begins to warm up after a period of cold, gibberellin activates the seed's onset of germination......
.....GA-3 can be used to skip the long period of stratification. Even seeds with hard shells and seeds that are difficult to wake from their hibernation can often be sprouted in a much shorter time than usual. Slow germination times often cause the seed to rot or dry out before the germination starts. A solution with GA-3 is used to soak the seeds, 250 ppm is sufficient while 500 ppm is recommended for most of the difficult to grow seeds

Oh and good to have another Sativa hunter watching along :thumb:

I have somewhere on the order of 2500 of these BD seed, thinking of popping 100 of them mid-March and do a proper hunt ;)

Whooo hoooo!!! Proper hunt indeed!! Hahaha
 
@GardeningGnome,

That information is right on the mark. Gibberellic acid (GA3) is a natural plant hormone used quite extensively in horticulture, especially fruit crops. It is used to produce “seedless” fruits like grapes and watermelon.

As cannabis growers, only converting a female to produce pollen and breaking seed dormancy is useful to us but:

100 - 200ppm for female pollen production
200 - 300ppm to make a male produce female flowers (ppm might not be 100% accurate)

Over 500ppm will prevent flowering - male or female

And 250 - 1000ppm to break seed dormancy - be careful with this one though, GA3 causes massive stretch and seedlings can grow themselves to death.

Lovely knowledge you are dropping on me here Celt... Thank you. Thank you. Thank you.

I will be following your adventures like Huginn and Muninn.
 
Evening all,

As promised, I have mapped my light at various heights and here are the results.

Now as I am unwilling at this point to dish out a few hundred dollars for a good PAR meter or a few thousand for a spectroradiometer, I am using a cheap LUX meter that reads to 200000 LUX.

This method is good for ballparking your lights but is unlikely to be as accurate as an good PAR meter from Apogee, but they do post conversion factors for various lights to convert from LUX to PAR.

For those using 3200k LEDs, you can use the same conversion factor (0.017) to get a PAR value.

For those of you using burple lights, to the best of my knowledge, no one makes a PAR meter to measure their output and a LUX meter will not work. This doesn’t mean you are SOL though, with a lot of math, and knowing the PPF of each colour LED, you can work out the PAR output for a given area.

CREE has the PPF value for some of their LEDs (white, red, blue) in their spec sheets. As for other chip manufacturers, no idea.

Back to my light measurements, you can see that around the edges, the output doesn’t vary significantly, but the centre goes up dramatically.

The average DLI climbs by approximately 0.5 per inch between 24 & 16” heights.

OK, lecture over, let the questions roll ;)
 
Quick update,

Had a lot of visitors over the weekend so not as far along as I’d hoped to be at this point but here is where we stand:

Slow boat from China finally made port and I got my irrigation parts yesterday.

The seed tent is chugging along, no real signs of pollen yet but looks to be some pistils browning so maybe.

I am off to the city today to pick up the steel rod needed to make the rest of my pots and racks, so hopefully I can get them built this week and the BD girls into their new digs.

As the new pots are not ready yet and the girls were at 7-9 nodes, I decided to give them a new hairdo and this is what we got.

First off, the girls were arranged according to height and pots numbered 1 - 18

The 3 tallest girls in the back row left, are likely Sativa Dom suspects, along with the 3 paler girls directly in front of them. Those 3, second row left, are a week younger and have easily caught up to the majority of the girls.

The 3, front row right, are my Indica Dom suspects and the rest likely 50/50 phenos. Time will tell.

Next we have the girls with there new dos.

I have left 2 nodes on each plant, they may or may not get a second cut, I want 4 tops per plant in this setup. I may give half of them a second cut just to compare results and see if it has any advantage.

The top of each plant became a clone in solo cups numbered to match the mother they were cut from. I have tried various cloning methods over the years with varying results and never consistent between methods. Sometimes a method would produce excellent results and the next time using the same method, results were hit & miss. The method I have had the most luck with, when cutting from seed plants, is to just use rooting hormone of some sort and stick them in wet soil with no humidity dome like this:

This round, I am using reamended soil rather than seedling soil, and I put perlite on top as fungus gnats are a bane to organic soil growers if you let them. We will see how this works in the tent with the mothers for a few days.

Tent is running at 75F and 40% RH this morning and the fan shut off. The tent is big enough, for girls this size, that I really don’t need the air exchange and zero air flow is better for the cuttings.

Thats it for now, tune in next time when the BD girls will be moving on up into their new digs.
 
Hay Celt I just skimmed through but you have some Great stuff goin on in your journal. I am very interested in making seeds in the future and when I do I will have Lots of questions. I hope you don't mind me taking a seat in the back and follow along
 
Welcome aboard @PCaddict, pull up a chair, there’s some Blue Dream, THC Bomb, Cluster Bomb and Pineapple Chunk in jars on the bench, help yourself ;) There’s also a local strain bred by a cousin of my father’s that I met for the first time a few months ago, but that’s been set aside for hash which may get made today lol
 
Ok friends, due to a recent discussion on another thread about the price of seed, I’ve decided that for those of you that live in Canada, let’s have a contest here.

As you know, I am pheno hunting in this BD grow, seeds are from my harvest in January.

So, of the 18 plants pictured above, tell me which ones you think will be Sativa Dominate. I will be judging these plants about 5 - 6 weeks into flower as I will be able to tell by the smell and growth then.

For those that have made their guesses before I flip them (about 2 wks from now), live in Canada and guess at least 2 plants right (assuming there are 2), I will send you 10 Blue Dream seed and some Pineapple Chunk seed if she produces.

Free seeds sign me up. Which picture do we choose from?
 
The Celt said:
Make your choices from the picture where they are lined up according to size :) remember, the 2 in the second row at the left end are about a week younger ;)

Tis a hard choice to make. But for some reason I'm drawn to 4 and 7. Either way lots of potential good smoke you have there.
