Seedling/Veg: 18 hours on, 6 hours off (18/6). Flower (photoperiods): 12 on, 12 off (12/12). Autoflowers: 18/6 or 20/4 throughout entire grow — they flower automatically…
Do autoflowers need nutrients? Or just soil?

Why did my seedling stop growing? 2 weeks old and stalled
Most common causes: overwatering (let soil dry between waterings), cold temperatures (below 68°F slows growth), root bound in tiny starter pot (transplant to bigger container),…
What's the difference between indica and sativa growth patterns?
Indicas grow short, bushy, and wide with fat leaves. Sativas grow tall, lanky, and stretchy with thin leaves. Hybrids are somewhere in between. For small tents, indicas or…
Can I use tap water for cannabis?

What temperature should my grow tent be?
During veg: 72-82°F with lights on, 65-72°F lights off. During flower: 68-78°F lights on, 60-70°F lights off. Slightly cooler temps in late flower can bring out purple colors in…
How do I know when my soil is dry enough to water?

Male vs female plants — how do I tell the difference?

What does "curing" mean and is it really necessary?

How much does it cost to grow one cannabis plant indoors?

My plant is 3 weeks old and the very tips of the leaves are starting to turn brown/yellow and feel crispy. The rest of the leaf looks green and healthy. What's happening?
Can I grow cannabis with just sunlight through a window?
I live in an apartment and can't set up a tent. My south-facing window gets about 5-6 hours of direct sunlight. Can I grow a plant there or do I absolutely need a grow light?
Do I need nutrients in the first week of growing?
Just planted my seed in Fox Farm Ocean Forest soil. Do I start feeding nutrients right away or wait? I bought the Fox Farm trio but don't want to burn my baby plant.
When should I switch from veg to flower? First photoperiod grow

What size pots should I use for autoflowers?
I keep seeing conflicting advice. Some say 3 gallon, some say 5 gallon. Does it really matter that much? I have a small 2x2 tent.
