Danger of Humidifier
Good morning everyone. So I've recently set up my new TS1000 and I'm wondering is humidifier dangerous for LED lights? It's directly under the light 60cm. And how can I regulate the temp in the room without new equipment? It's too high at the moment.

Hi guys just after a bit of information regarding flipping. When you guys and gals flip do you increase your light output gradually or do you just go straight to full power. Any information will be appreciated thanks growmies

Increase light hours autoflower
My autoflowers are 6 weeks old and showing flowering signs. Can I increase the number of light hours from 17hrs to 20/22/24hrs? Does it cause light stress and can trigger vegetation or make it hermaphrodite?

Grams per watt
What’s the best gm per watt that someone here has gotten on a single plant? I’m aiming for 1gm per watt but doubt that she will yield 315gm once dried.

Switch Fixture During Bloom
Plant exceeded growth expectations. Now the light penetration is not at the desired PPFD half way down this crowded plant. Any reason not to upgrade to a 250 bar light during flower with Autos?
