Optimal conditions

Seedlings and clones like RH levels of 65–80%. Remember, these young, fragile plants have weak root systems. By increasing humidity levels, you’ll allow them to take up more water from the environment and focus on developing strong roots. At this early stage, you’ll want to keep temperature levels at around 25°C during the day, and around 21°C at night (77°F and 70°F, respectively). Vegetative plants, on the other hand, tend to prefer moderate humidity levels. There’s no exact figure to follow here, but you’ll want to stick somewhere between 55–70% depending on the strain. Temperatures should sit between 22–28°C (71–82°F) during the day and roughly 18–24°C (64–75°F) at night. Vegetative plants have strong root systems and will absorb more water from the soil, which is why most growers drop humidity levels slightly during this stage. At the early flowering stage, most growers agree that plants benefit from lower humidity levels. Again, there’s no ideal figure to aim for, but many will stick between 40–50%, occasionally pushing to roughly 55%. You’ll also want to drop temperatures to about 20–26°C (68–78°F). During the late flowering stage, try to drop humidity to about 30–40% and keep temperatures around 18–24°C (64–75°F) during the day, followed by slightly cooler nights (16-20C in the last few nights). Keep pH between 6.0 6.5. Hope this helps! Happy growing.. 👊
