I have had a high humidity of 70% once and am quite worried. But the meter was on the floor of the tent so may be a higher reading.
Thanks for your reply buddy
Daily Care in the Vegetative Stage
In the vegetative stage, your job is simple. Cannabis plants grow fast and are tough in the vegetative stage.
To keep your cannabis happy and healthy, you need to do the following
Provide water – Water plants when top inch of soil feels dry to the touch. In containers, make sure water can drain freely out the bottom. In a hydro setup, there will always be plenty of water.
Nutrients – if providing nutrients, start using the included nutrient schedule at ½ strength, and only raise to higher levels of nutrients if needed. Simply add the directed amount nutrients to your water before giving it to plants or adding to reservoir. Manage pH levels if using liquid nutrients.
Provide light – Keep plants in sun or use your vegetative grow light as directed. Simply turn grow lights on and keep at the recommended distance from the top of your plants. Outdoors plants will continue vegetating until days start growing short. Indoors plants will stay in the vegetative stage as long as they’re getting 18+ hours of light a day
Not too cold, not too hot – Vegetative cannabis plants prefer a comfortable room temperature or slightly warmer. 70-85°F (20-30°C) is great. Avoid low humidity in the vegetative stage if possible. Never allow plants to experience freezing temps
Air circulation – Make sure cannabis gets a constant supply of fresh air so plants get the CO2 they need to grow, and keep air moving so there are no hot spots and leaves are always moving/rustling. Outdoors you may want to put up wind breaks if it gets too windy so plants aren’t being waved around.
