Hi
@BigDaddyK "Stop Grow"is a product manufactured by Spanish nutrient company Pro-XL. It's a plant growth regulator that claims to stop vertical growth and induce flowering, not only enabling us to control the final height of the plants, but also reducing flowering time by around a week. According to the manufacturer, this also automatically leads to larger, denser buds and an improved flower formation. As an added bonus, Stop Grow is compatible with CO2 use, for optimum results.
6-Benzylaminopurine or 6-BAP is a synthetic cytokinin, a growth hormone which is used in agriculture to improve flower set and increase productivity. Some cannabis growers have reported good results from applications of 6-BAP but it has its disadvantages, being difficult to source and complicated to mix and apply as well as being toxic and potentially harmful to human health. When it comes to a product we intend to consume ourselves, we prefer to keep things as natural , sativa varieties are very prone to stretching and can be a true challenge to grow to full maturity indoors, as they tend to keep growing upwards well into the flowering period. Over the years, experts in growing these more tropical strains have found they can manage the stretch by keeping the plants in smaller pots for the first four weeks of the bloom period, only re-potting to a larger pot once stretching is over.
48 hours darkness. Ive seen reported for Sativa and Sativa-dominant hybrids is to subject plants to 48 hours of complete dark to help transition before switching to the 12/12 light period for flowering. Good luck mate 👍
