Heirloom's thoughts on making feminized seeds.

No Pic Update...just blah, blah, blah....

In fact no reason to read it all unless you want to make feminized seeds.

The status of feminized seed projects....

Yesterday it was noticed that some seed pods are already opening on the Blue Dream. Two seeds were plucked. Fully developed and dark with patterns. She has a little less than two weeks left before harvest. Looking good for the seeds!

Sib1 Dark Devil Auto fem seeds.....check
S1 HSO Blue Dream pheno 1 fem seeds.....check
Hybrid fem seeds of the above.....check

That's more checks than I thought I would have in this category, this year.


Fruit Punch is next up on making S1 seeds. The STS has been sprayed twice now. First the day before flip, and again one week later (yesterday). The seed host plant is vegged up, healthy and just waiting another week...maybe two....before she gets flipped too. I decided to pop another DDA Sib1 seed in hopes of it catching some fruit punch pollen. Devils Punch Bowl anyone????

For the fruit punch, I've decided to spray the STS 1 time per week until pollen sacks are nearly open. Maybe 4 weeks, we'll see how long she takes to sack up.

The (current) STS recipe/procedure is as follows:

Part A = 1 gram Silver Nitrate dissolved into 60ml distilled water
Part B = 6.25 grams Sodium Thiosulfate Pentahydrate dissolved into 240ml distiller water

Mix part A into part B stirring rapidly. You don't have to mix all of it up at this point. I mix smaller quantities from the part A and part B, but the ratio must remain 1 part A to 4 parts B. I mixed 20ml part A into 80ml part B and kept the rest for future use.

So now you have STS concentrate that must be diluted, lest you burn the plant. 5:1 is the ratio I am currently trying. That's 5 parts distilled water to 1 part STS concentrate.

My 100ml total concentrate mixes with 500ml water to make 600ml spray-able solution.

We soak the plant from top to bottom, inside, upside down. Heck, If I had a vat of STS, I would just dunk it. Sprayed twice on spray day. Once mid day and she's kept away from bright light. Once again before lights out and she's put away. That 600ml spray-able is 5-6 weeks worth for one plant at one dual soaking per week. Enough for 10-12 or so full spray soakings on a dense 12"ish indica. We tend to use about 50ml per spray session. Wispy, leggy sativa like strains use less.

We have not tried STS on just one branch. We've found it easiest to handle a whole small plant in a #1 pot, who's purpose is only to produce pollen. I won't be asking them to reverse some branches and bear seed on others anymore. Much easier to pull the whole small plant from the tent, spray it all over in another room and keep it out of the bright light etc. I'm sure even smaller plants would be fine, solo cup size. You really don't need a pollen plant as big as we're making.
