can you (or anyone) elaborate on what you mean making seeds?
Well you're gonna need pollen to make seeds. That's a given. How you obtain that pollen can come from a few different methods.
If you want to make regular seeds which are seeds that will produce both male and female plants, then you'll need a male plant to collect the pollen from.
If you want to make feminized seeds then you will have to obtain pollen from a female plant. Yes that's right. Female plants can give you pollen too. In order for that to happen you need your female plant to produce some male flowers and to do that requires any of these 3 methods.
#1. The method that is most frequently used for producing reliable female seeds is to let a few buds on your plant keep flowering after you've harvested the rest of your bud when it was ready. Your plant will feel the impending doom looming upon it and produce some male flowers in a desperate attempt to self pollinate. When the male flowers are ready, you collect the pollen and store it to pollinate the next plant you grow. Because the pollen came from a female plant, the seeds it will produce will be at least 98% female.
#2 Another method to use is the Colloidal Silver method. I won't go too deep into it but using a prepared compound(search colloidal silver) to spray a few of the buds on your plant will cause them to do what method #1 does. Again save the pollen to pollinate your next plant.
#3 This method was one I didn't know about until my last grow but it has turned out pretty solid so far. If your plants are showing only female sex and you put them under real stress, this can cause them to produce some male flowers. At the beginning of flowering on my last grow the plants experienced a few nights in a row of really, really low temps. A few days later I noticed that a few nodes had begun to spit out hermaphrodite flowers. I was unhappy at first but did a shit ton of research into it. What I found lifted my spirits as it turns out the pollen created by those flowers would produce mostly feminized seeds as well. The bonus there was that I could actually use the pollen on that round of plants instead of collecting and storing it for next time. So that's what I did and now I have a ton of those seeds. More than 12 have been grown out and they have been female so far. With the 6 plants I'm running now I actually had 1 male preflower growing out of 1 side of 1 node. I plucked it and all is well.
The final method is one that isn't recommended. If you have a plant that naturally shows hermie traits you can use that pollen. Problem there is that the seeds you will produce will mostly be hermie as well. If you don't mind seeds in your weeds then by all means press on but you'd be much better off using one of the above methods. The top 2 being the most commonly preferred.
I'll be using method #1 to obtain some pollen from my current run to cross with my next plant which will be Melon Gum from Dr. Underground. Strawberry Blue x Melon Gum sounds good to me. I'll probably use method #1 again on the Melon Gum to obtain some of that pollen so I can back cross as well as pollinate my Fruitylicious when I run that after the Melon Gum. Blue Fruitberry Melon.
