My first grow was inside an aquarium on its side. My second was in a homemade grow box then came a closet for a bunch of grows, then outdoors and now I have a tent.
The best advice I could give you is start yourself a change jar specifically dedicated to setting up a grow tent.
For around 500 bucks (saved over time) you can set yourself up for years to come.
My current grow still needs another air cooled hood for my second light but otherwise I'm fairly set up.
A future shopping list for you can include;
- 1x Grow tent (comes in different sizes)
- 1x light (LED/HID usually comes with hangers)
- Ducting (silvery and flexible)
- Inline fan (the bigger the fan, the more airflow)
- Amended Soil/Hydroponic Setup
- Nutrients
- Zip ties (handy for everything)
- Carbon Filter (a good one eliminates smell)
It would also help to learn about defoliation, lollipopping, LST, Supercropping, topping (F.I.M-ing aka Fuck I Missed), ScroG-ing and other yield increasing techniques.
Anyone can grow cannabis, it's a weed and will grow almost anywhere. The trick is growing great cannabis.
