Does too concentrated STS cause inviable pollen? Despite dabking seeing "seeds all over", There were none. someone didn't get the joke. This fem seed run failed. Lower concentrationn gave 1000s, instructed concentration gave 100s, this OD gave zero despite 100% conversion.

Hey,
Yes, using too concentrated STS (Silver Thiosulfate Solution) can lead to inviable pollen even if you see full conversion to male flowers. Over-concentrated STS can damage the pollens viability leading to poor or no seed production as you experienced. It’s best to stick to the recommended lower concentrations for reliable results

Helmet head help!!!!So I had a seed that sprouted days ago that still had helmet head. I read online to gently squeeze with a pair of tweezers& remove it . I tried and soon found out that it just wasn't done it business. It was a few inches tall though. Will it bounce back or die. Anything I can do?

Unknown Intruder alert(?)I have 5 Green Crack Autos.
A random plant popped up in one of my houseplants, no clue as to what sort of seed it is.
Will it cause a problem being in the same tent as the autos?
Can the random one alter the autos depending on its sex?
Or
Can the autos affect the random?
