Making feminized seed

Discussion in 'Cannabis Breeding' started by TimJ, Oct 16, 2022.

  1. First let me start off by saying I am not an expert at breeding. I don't want people to get off on the wrong foot here. I simply make seed for myself,family and friends.
    I have been making feminized seeds for several years now. Timing is important both in the maturity of your pollen and your female pistils. I use two clones from a mother plant to make my seeds from. They can come from different varieties if you're making a cross. I use a 1/2 gallon pot for my pollen donor and a 1 gallon pot for my female. I start to spray CS on my pollen donor 1 week prior to flipping to 12/12. Then spray for one week more before I flip my female. I continue spraying my pollen donor until I see well developed pollen sacs. By doing this I find I have the highest production of seed. A female needs to be around 3-4 weeks in flower before her pistils are mature enough to accept pollen. The pollen from our donor is not ready to drop mature pollen for at least 5 weeks. Sometimes 6 weeks. Once my pollen donor starts dropping pollen I gently shake it over my female daily for 1 week. This insures maximum pollination of my female. I run my female through her full flowering cycle. I do a progressive seed harvest. Every few days more calyx's open exposing mature seeds ready to drop. I find once the seeds are maturing 100 + seeds every few days is average until she is done. Anyone can browse my journal to see several of the photo period crosses and BX1 I've made in that journal. My latest venture in feminized seeds making was an auto-flower cross. I now have her offspring at 50 days old. Good luck and if you have questions or can offer insite in any way do not hesitate to do so. We are all here to learn and share with one another.

    I prefer to use a 9v dc battery as any larger 20-24v will only increase the silver particles,
    I only spray one lower down flower, most the time its the lowest and latest flower to emerge
    I then apply the long awaited pollen to again the lowest flower on that very same tree,
    and mark both sites, I often apply the pollen to other strains in again the same position

    I allow the plant to get to harvest, take the above regions but leave our pollinated flowers to continue alone
    as I dare, any screwups here on my part are 'fixed' by Rodalization
    True about the pistols its vital to get that 'right time' just before the pistols die back, is the best time to apply pollen, often the first pollen from a female plant can be sterile, so capture the pollen as its in full swing, a tsp will do thousands of plants, I freeze it for 2 weeks and apply with a cotton bud, after covering the plant with a large towel ..I wait for an hour then spray heavy with water to neutralize any escaped pollen then return her to the grow room
    Timing is important many times I've had the female ready as the male is miles behind, or the other way round, best is to have emerging CS pollen from the last crop as your female is just getting into flower..its tricky,
    so plan it all out, having good real 99% silver, not coins is a great start

    I've used the 9V battery and even tried the two 9V batteries connected. I find the particle size too large with the two 9V batteries connected. I didn't have the best results using those methods. I have much better results using an old cell phone charger with alligator clips connected to the leads. Most cell phone chargers have an output of 5.0-5.1 volts. I believe the smaller particle size of the silver works better in my experience. It does take a bit longer to get to 20-30 ppm. But, I find I get the best results using this method.

    Bonus: To double check your silver is actually suspended in the water. You can use any laser and shoot through the water horizontally. In distilled water the laser will not show up in the water column. When you check your colloidal silver your laser will magically appear in the water column. This is a trick I learned from @3Deez.

    On another subject. I couldn't find definitive proof of the silver particles actually becoming systemic within the plant that has been sprayed with the silver. But, it is likely and I would not consume the plant that has been sprayed. I grow enough weed that I just toss whatever plant matter is left after I harvest seeds.

  5. If you are ever having a hard time reversing one with colloidal silver, I'd try going the silver thiosulfate route. Some breeders sell STS reversal kits to make this easier.

  6. Thanks for the advice @gxxire and for dropping that knowledge on us. I have used Tiresias Mist once and it worked well. I'm currently back crossing a Nirvana seeds Raspberry cough. My last attempt was a failure. I ended up crossing the Raspberry cough female I had in waiting with White widow pollen I had on hand. I'm hoping for a better outcome this time along. I'll need to check and see if I still have a little bit of that Tiresias Mist left.

    I found the Tiresias Mist I had used once before. I still have about 1/3 of the 2oz. bottle. After reading the MSDS on this product it appears to be colloidal silver, not silver thiosulfate. 20221016_191602.jpg

  8. Just gettin in to this lol
    Got karma reg seeds acid dawg and was trying to find a strain to cross to it but have to be careful for herms on the chem and sour ranges apparently so selecting is very careful and flavours obvious I’m not keen on lol

    I love skittles but can’t find anything solid on who has good reg f3 up or bx in them in uk
    And no solid on herming a cross to chem

    skittles is heavy yielders normally so with the dawg acid being big yielding too I can’t see my yield dropping though I’d worry for mould lol the skittles should space buds out with the sativa structure to help that as it’s bobbly

    stil researching lol

    so Untill then I’m going to store my pollen
    And try copy what you have to get some fem seeds I can run in my main crop I love this strain so if I can get 100 seeds fem instead of running clones I would be made lol seed vigor always wins the stems are triple cuts lol and yields insanely more I always thaight it would copy the plant exactly but it doesn’t only in flavour and style

    Can you breed from fem seeds??

  9. Chem strains were never my first choice. But, we all have different tastes. I loved Nirvana's Zkittles. I grew it from their feminized seed. I have pictures of that whole grow in my journal. She was mainlined to 8 tops. You can breed with a feminized female or a true female to make feminized seed. I make feminized seed because I only grow for my own needs and have a few small spaces to grow in. I find mainlining works best when the plants are grown from seed. And mainlining plants is my preferred training method for my small grow spaces.
  10. I’ve been playing with mainlining lol
    In that case purple city has a watermelon skittles cookie that gives 2.8gpw but the cookies makes balls wk 4 ya need to pick
    But there gmo nana is flawless

  11. I just topped my next mainline for the first time. That's some high gpw. I don't grow for weight. I grow for the quality of medicinal properties. I don't think I would grow a strain I needed to pick off pollen sacs from. I do understand there are some great strains that are prone to hermi. They are just not strains I care to grow.

  12. I understand ya it’s a mental flavour with one of the best highs I’ve had lol but ye last grow I saw how o got the odd seed but for quality man it’s next level and sooo tight the yield was off the chart whitch I didn’t half expect them was told cookies you must remove balls sacs

  13. I found a guide that says using sts spray you spray one time wait 3 weeks and spray 2nd time
    With cs it sounds like u have to spray every day ?

  14. @2cent420, I have no experience with STS. I use Colloidal silver as it's cheap and easy to make. I do spray CS every day until I have pollen sacs opening. It's really not a big deal as I do this solely as a hobby and not for resale.
  15. I purchased a small 2x2 tent, a LED light and a fan just for making feminized seed. I have around $125.00 in this whole setup. Here's my current feminized seeds grow. This is a Nirvana seeds Raspberry cough. She is starting to make seed and he is still dropping pollen. They will stay together for another week and then he becomes worm food. I also progressively harvest my seeds for several weeks when they become mature. From the 1 gallon pot she is in I should get 500-700 mature seeds after sorting out the undesirable ones. 20221117_173456.jpg

  16. I thought I'd show a picture of the donor Raspberry cough. She is just starting to fade and still has a week or two before I'll harvest her. 20221117_174710.jpg
