-i haven't been concerned with humidity. it's maybe 50-60% humidity outside on a permanent basis. these are indoors.

-they are well ventilated, with alot of fresh air, but not so much direct breeze from fans or from open windows.

-temperature inside varies through the day between 18-26 degrees celcius.
it was colder in their first month

- i grow with soil (coco in the small pots initially)

- i germed them in disposable little cups which you can plant directly into the soil and disintegrate naturally. i took them out though when i planted in the mini tercotta pots. because the pots were small, the little disposable cups looked big and would probably take 5 years to dissolve in coco coir.

Q2) i've seen alot about 16:8 daylight hours to darkness. they are in veg phase, does pushing their light exposure artificially help them veg quicker? is sleep cycle only for flowering stage? i have heard 24:0 is fine for veg. do they have to be in these ratios, or can they get like 19:5 for example.
