Female pollen from a feminized plant

Hi. Gonna attempt making feminized seeds using colloidal silver. Is it OK to use this technique on a feminized plant to get the pollen, or is it only advisable to force regular females to grow them nut sacks?

Yes it works. Most people use it on feminized plants because so many strains are not available as regulars and that's the only way to make seeds from those strains.

Good to go then thanks guys
:lol: I thought I'd read somewhere that feminized plant pollen isn't (very) viable or something. Can't remember now, I'm probably getting mixed up with something else :joint:

When inducing a female to make pollen you should be aware they don't normally make as much pollen as a regular male. Also, because the time it takes to "reverse" a female can vary (some are more stubborn than others) you may want to have several female plants you intend to pollenate in varying stages of flower to ensure when the she/he is ready to go, there's at least one female of the desired strain ready to receive. Good luck.

Once the "fems = hermies" myth started losing its power the femphobic hippies started spreading myths about fem seeds lacking something or other from males and therefore couldn't be used for breeding.

Also be aware that the pros are all using silver thiosulfate (STS) instead of colloidal silver because it more reliably reverses females with just 1-2 applications... If you have a decent scale you can make assloads of it from a small amount of easily obtainable sodium thiosulfate and silver nitrate or you can buy premixed concentrate from Riot Seeds.

Yeah basically got a mature clone ready to put to flower whenever, so hopefully by the time she makes the pollen there'll be a few branches in the tent to pollinate which are just seedlings at the moment.

I heard this. Isn't the inventor of this from Sweet Seeds, Mohan Ram (?) Anyway just had a quick look and I can source both of them ingredients. I wouldn't know how to mix them though. Is there a recommended guide anywhere you know of?

He may have introduced it to the Cannabis breeding world, I don't know, but it's a legit technique used by botanists/horticulturists

If there is nothing to pollinate when it reverses then dry the pollen out and freeze it. In individual little paper packets. Pull one out of the freezer when you're find a good female and hit it with pollen.
I haven't tried it but I have read it can be really hit-or-miss. Have you had good success with frozen pollen?

This is the method I use. It works and you only need to spray once or twice. Be careful with the solution as it will stain anything you get it on. There is also two types of sodium thiosulfate. You want to get the (anhydrous) type which is NA2S2O3.

I have. Up to eight months to a year with freezing it in a single envelope. Another person suggested freezing in smaller individual packets. They said they got longer time. Makes sense. With one big envelope it draws moisture everytime it comes out of the freezer.

My last plant I froze in small packets and I will see how long it lasts.

The key is to make sure the pollen is bone dry.

Is this how to mix for reversing? I just notice it says Tissue Culture at the top...

I will check that out. When I looked briefly on amazon I didn't see that it specified what type of sodium thiosulphate it was. I'll be sure to get the right one.

I was chatting over on another site and a user there says he freezes his pollen but tries to use it within 5 months. Says it gets less viable the longer it's kept which makes sense I suppose. Nothing lasts forever right.

I've regular gotten 6+ months from pollen. I think individual packets will extend that to a year+.

Hi ,

I am going to create pollen from feminized photo by spraying colloidal silver . I am going to spray it on same grow tent where my other feminized photos going to follower . Is that ok ? or will whole tent will get seeds ? Also i have very small plant which i decided to create pollen (seeds) (less than one galoon pot ) is that enough to breed :) thank you guys
