So today was the 6th day of spraying.. 15 days total. Recommend to put females to be pollinated in between 14-24 days after initiating flower and spraying of reversed plant.
Going to try different times. Just put in Durban and pure indica.. likely put in PotG and blueberry in there in 3 days from now.. probably try one more solo cup one to get just a few seeds from as well but it’s looking like crosses will be
BLUEBERRY x
-Pure indica clone
-Durban from seed
-PotG 1 clone
-Blueberry clone
Reversal plant is looking like it’s flowering.. pistils showing for sure. Should start seeing pollen sacs within a week or so..
————MIDWEEK UPDATE ———
So it’s day 18 or 19 and this still looks like regular ass flowering plant. No real signs of pollen sacs. Worrying me.
Day 21 now I got formations that appear to be the beginning of male flowers so that’s good!
+--------PROCESS---------+
So here is a general run down of how I ran this and what I used, etc.
PRODUCT
Product used was Twenty20 Mendocino - 2 part STS (Silver Thiosulfate) purchased on Etsy for $30 bucks.
This is a two part product you mix and its good for about 30 days after mixed , then it declines in efficiency.
They have detailed instructions on their site, as well as a YT video outlining application of product

PLAN
Idea here is to make a few crosses by reversing the Blueberry pheno I found, then pollinating a few females I have ( Some from seed, most from clone and hunted)
Reading up on this and as suggested by their website - Timing can be tricky. You want to wait 2-3 weeks after initiating the flowering and reversal of the ReversedFem before you initiate flowering of the female seed donors or females that will be pollinated by the reversed female Blueberry.
So given their indication that timing is very important - and this large window they suggest starting your females in flower after reversed fem (they said wait 14-25 days).. I hatched a plan to help account for any timing issues that occurred. My worry is that seed plants have a slower trigger than clones in flower.. as well as strain differences and pheno differences. So, I started spraying my large Blueberry Fem on 1/31 and put in 12/12 that night, then on 2/3 I did the same with a smaller solo cup clone. This allows me to have a little buffer if there comes any issues. Although ultimately we want the large one to be the main producer and pollinator.
After that I planned to put half the females in about 15-17 days later, then another about 20 days after..
PROCEDURE
So procedure panned out similar to the plan
JAN 31
Sprayed large Blueberry fem with STS and threw in 12/12
FEB 3
Sprayed Large BB and also solo cup clone BB and threw that one in 12/12
FEB 6,9,12,15,18,21,24
Sprayed each of the two BB fems as instructed by Twenty20 - around nodes and new growth.
As weeks went by I wasnt seeing male parts so I delayed the fems a few days.
FEB 17
I introduced the first females , Pure Indica and Durban I believe, into the tent with the Reversed BBs
FEB 20
I introduced the rest of the females to be pollinated into the tent - POTG, Blueberry Clone, and a small Thanos clone (astaphanos keeper cut)..
FEB21-22
First obvious signs of male pollen sacs surfacing
FEB 27
Full blown male sacs showing on majority of bud sites on plant.
None appear to be opening up much yet. I would wager no pollen is active in the air.
POLLINATION
I will attempt mainly naturally pollination with some assistance such as tapping the Reversed plant over the fems when the sacs are ripe.

About how much pollen would you say you got from 1 reversed female?
How much less would you say than a reg males pollen?
I'm about to force females for pollen to make fem seeds & I was wondering about how much to expect. Or should I force an extra plant to ensure enough pollen for my female.
@cheetah844, oh and I think you could get better results likely but this blueberry is a very tight noded plant and made it tough to spray well. So it wasn’t a full on reversal it seemed like it was about 60% male parts and 40% female. This was problematic as I described in this week update. The female trichs reallllly like to grab that pollen too.. whereas a male wouldn’t have that issue.
Why such jumping over pollinating, if fan and time would do same, just move pots of future seed plants around tent and position reversed plant in front of oscillating fan ??
Wonderful job for other growers, HUGE Respect !
@AsNoriu, lol thanks bruh. And I’m not sure maybe I did something off.. I’m curious to have another go with the STS and maybe it will be easier.. it was an awesome learning experience tho. Plus I got me thousands of fem seeds 🙀
