I used a specific colodial silver I can post later, I am trying the gibberellic acid method this time as it’s organic and you can actually still use the bud unlike the silver method. Pyro check out my YouTube channel I kinda explain how I did it with a few autos. I’m doing it now with photo plants green crack/Durban poison/lemon OG candy/ Girl Scout cookies/Night nurse /Skywalker OG and Vader OG. I’ll be covering the photo plants on my channel(as best I can) Essentially, you spray the bud sites a week prior to flower 1-2 times a day with either gibberellic acid(specific concentration) or colodial silver(30ppm) worked for me. With autos it’s tough because unless you e grown a strain before, you don’t really know when it’s supposed to start flowering and the week prior is critical. I start autos once there is 4-5 sets of fan leaves. With photos you can do for a week then switch light to 12-12 and with both methods you wanna go 2 weeks into flower and you will notice male pollen sacs forming at those sites you spray/brushed on either product. With this next experiment I’m gonna spray an entire plant with gibberellic acid because I have 3 mature clones of each strain. About the 8 days into flower I’m gonna switch lights to 12-12 in my other tent of plants I wanna pollinate. Once the pollen sacs get mature, or right before, I’m gonna put the unsprayed plants and hermi plants in a 2x2 tent I have seperate. I’m going to pollinate the same strain with same strain, I’m going for max seeds and I want to be able to collect and store pollen for later cross breeds. After about 4 days of pollen going on that plant I will remove plant with sacs/ collect and store pollen then dispose of plant. And on to the next plant, it takes 3-4 days for pollination to take effect and absorb the pollen. Then you spray the hell puta he pollinated plant with water to destroy the remaining pollen that didn’t get absorbed. I will do this 5 times. And later with a northern lights but I started that seed super late. I’ve done a ton of research on this and actually produced a bunch of seeds and some cross breeds also with purple Ryder/white widow and white yoda and Pineapple Express.
Any questions ya got feel free to ask. I don’t always check here but I do reply pretty quick with you tube comments.
