Feminisierte Samen selber produzieren

Thanks for your reply. A lab would be cool now

That also sounds like a lot of effort that would be worth it if the result is right. Cleaning lamps and especially all ventilation equipment is also relatively a lot of effort.

However, in Ed’s book, the topic is treated quite “roughly” and I think I’ve read here that you also prefer knowledge from books rather than the internet. Could you possibly tell me what other books you have that describe the topic a bit more intensively, especially with feminized seeds?

Regards and have a nice weekend

I only have 2 books, both by Rosenthal, one is Marihuana Growers Handbook and the other is Cannabis Anbau mit LED (Cannabis Cultivation with LED) for the right choice of lamp.

I had informed myself for half a year in advance on the internet and on various breeder websites as well as on YouTube after I had read it in the book, and I wasn’t much wiser afterwards. The best explanation was in the 2 videos I posted here. Long story short, my thought was “what he can do, I can do just as well”. So I got the stuff and just tried it out, on the windowsill and put it in a cardboard box for the dark phase. I don’t need to clean it; it’s simply disposed of and a new one is taken. It then took three weeks and a few attempts, not including the production of the silver water, and then you could also see the desired change.

Next time, I’ll leave the silver diodes in distilled water for 24 hours and start treating during the growth phase before switching to flowering. Then the desired effect should come faster.

Yeah, there’s a lot of nonsense on the internet

But the book makes me want more, and I’ll start a test with Gibberellic acid, let’s see how that works. I’ve also thought of a cardboard box now, that’s a pretty good idea Cuttings are currently rooting, and then I’m excited to see.

But you didn’t test the variant with silver nitrate as powder & sodium thiosulfate, did you? Personally, the method with the rods would be too much effort for me.

No, I didn’t.

was put together in 5 minutes, then waited 24 [hours] and poured into a spray bottle. You can also buy the stuff, however, the parts you need for production are cheaper, and the rods can still be used by your great-grandchildren.

This is one of the home-grown seeds. You can already see the pre-flower at the node below the tip.

Here we go again, this time with a Growlog to track everything. This time I’m propagating a single specimen to replenish the stock. Royal Runtz growlog - Grow with Jane

Today, the shoots were spread out a bit and the lighting duration was reduced by one hour so that I can start the flowering phase by the weekend. The upper shoots are treated daily with silver water.

Here’s a new picture of the Royal Runtz

Small Update, the stretch is in full swing and the first pistils are already visible. The male flowers are still awaited.

Today I performed a super cropping on the two upper shoots to limit their height. The colloidal silver treatment continues.

Upon closer inspection, I believe the first are forming. Although I tried to photograph them, it’s not visible in the pictures. Viewed with the , it looks like male flowers. Perhaps I’ll manage to get a clear picture in the next few days.

Today I took a picture with the and now you can see the nanners

Today I was finally able to take some good photos. The are so big in some places that it looks like they’re about to burst. I finished the colloidal silver treatment the day before yesterday; 14 days with three daily treatments served their purpose well. Currently, it’s Flowering Day 15.

Upper level looks like this
