What is shelf life of silver thiosulfate ("STS") in practice?
Sit_Ubu_Sit_Good_Dogstarted grow question 2y ago
I know it is recommended to use within 30days of mixing final solution.
However, what "works" can often be different from the recommendations. Has anyone used an STS solution they made after 2months? 6 months? How did it go?

Flowering/Preflowering/Showing Sex in Vegative stage?Today I noticed all my outdoor plants have pistils after being 3-5weeks outside. Is this normal and will they continue veg due to increasing days/temps? Also, could this be reversed with additional light? Currently in the 7th week of Spring with 14h light and 13h sunrise.5y ago

Should I plant my autoflower out in full ground at end of week 5?My autoflower just started week 5 and she's looking really healthy. I was wondering if it would be beneficial to plant it out into full ground by the end of this week. Weather is supposed to be 20+ °C by then. Would the benefits of full ground outweigh the cost of "repotting" ?6y ago

ThanksThank you very much for the advice. Ive never used dry nutes before. These are 100% organic. Only one bag for veg and a different one for bloom. Switch bag with the light cycle switch. Sounds easy so I'm looking forward to it. Thanks again for replying.Other. General questions
