What do think the minimal darkness that’s needed during veg for a photo plant? I’ve read a lot I’ve done the 18/6 for evey grow but would like to goto to 20 or 22 hours light for the last two weeks vegging. See any harm/Benifit ?

Photos need their rest and autos do as well. 18/6 is best even for autos.

When is the vegetative stage?This is my second grow ever. I plan to let these grow indoors until 4/20 and then transfer to bigger pots outdoors. When can I consider these plants to hit the vegetative stage? I have heard when they hit their first set of 7-point leaves but that seems long. Is that accurate?

Darkness and Waterless before HarvestTrying to find a definitive answer as to why, * 4 days no water and in total darkness before harvest. I expect this is to stress the plant to fully bloom, but not sure. thanks in advance.

New Light? Find a way to raise light? More Fans? Combination? (Light: 44" above ground level | Tent Height: 63" Day avg: 78.6f) Should i worry?What do you guys recommend as far as lighting for this tent? I have a 300w led light but at the height it's currently at it is producing a large amount of heat with my exhaust and two oscillating fans? I also have other plants in with my seedling so could the humidity cause it?

Changing DWC Reservoir. How often?Just out of curiosity... does anyone here go longer than 2 weeks without changing their reservoir in a DWC system? I have been changing mine weekly, but the more I read up on it, the more I see people say that you don’t have to change it that often. Thoughts?
