This is the female flowering room for this run. White walls black floor 3'9"x7'9"

Pics taken Jan 22 after a heavy defoliation pre-flowering.

Both the TS3000 and the SF4000 are at half power as of now but will change later in the flowering cycle.

This is the male flowering room for this run, silver walls silver floor, 4x4 Mars Hydro grow tent, Under a SP250 from Mars Hydro.

The plants all received STS treatment 5 days before flower, and every 5 days after that, they have been under 12/12 for 17 days.

I used to spray everyday as that is how I was taught to spray STS, but after making a comment in another thread someone said it is supposed to be every 5 days. So I went on an internet hunt for information and the only place I found that said to do it daily was from the person who taught me how to do it, many other sources said spray every 5 days. So this is my first attempt at the spray every 5 days method. Just wanted to document it for posterity.

I spray every 3 days, good to know every 5 days works

Even easier
I hope to do a labexperiment after this run and spray 3 plants with a 9 to 1 mix, 1 plant daily, 1 plant every 3 days and 1 plant every 5 days. Another 3 plants will get sprayed with a 5 to 1 mix, 1 daily, 1 every 3 days and 1 every 5 days. The pictures will then be examined and possibly the pollen weighed for a clear determination of which SOP is best for STS spraying. Provided I have enough meds and space to grow more meds so I don't run out.

Day 19 defoliation to open up the airflow and make STS spraying easier. Looked again today and found some info, seems only 2 or 3 treatments are needed, as I have done 3 now and I can see the formation of pollen sacs, I will stop spraying for now and keep an eye on them.

With multiple strains in the room you will have sooo much cross pollination you will not be able to verify seeds produced on each plant

If I'm understanding u correctly


There are 4 doors between the male and female room, male plants will be taken one at a time to a rinse station where they will be rinsed and dried and sit for a while for new sacs open, then the female of the same strain will be brought to the rinse room where it will be pollinated, both plants will be rinsed again and then returned to their rooms. The males will be allowed to finish growing whatever crosses they picked up in the male room, the females should only be pollinated by the males intended. There will also be several changes of coveralls during anytime there is a possibility of contaminating other females, bags will also be used to cover the plants during moves to reduce unwanted cross-pollination. Ultimately it's not an issue as the seeds are not for sale, just my personal use. The seeds harvested from males will be kept separate and shared freely with other growers in my area for a hunt. With 2 indica dominant strains and 5 sativa dominant strains the crosses should be quite varied.

I also have the same 7 strains in another room which will be pollinated by the corresponding male, it is these seeds I will be keeping to preserve the genetics I currently enjoy. And I do not have 7 rooms, one for each pair of plants, and I do not have the room to keep 7 mothers around.
I did talk to a horticulturist a few days ago and she advised me of a safer way to reduce the chance of unwanted crosses when I go to pollinate the females in the other room. And with her advise and my experience flowering the strains I have several times, it should be fairly easy to weed out unwanted crosses from the seeds I am keeping. Again none of the seeds I produce are for sale so the odd cross is not an issue.

As far as the STS sprayed plants, the seeds that come off the sprayed plants will be given away to other growers in my area that cannot afford to buy seeds very often but like to explore new genetics when they can. I know the plants I'm breeding are vigorous so the variety of seeds the males produce are likely to be vigorous as well. they are like bonus seeds full of mystery. Again these are bonus seeds, the seeds I will be keeping are the ones from the female plants in another room.
