I want to tell you about DIY stuff. A lot of it is garbage and or very inefficient.
This part of the grow cost me quite a bit. My stuff was ghetto rigged , I built all kinds of stuff, light fixtures, carbon filters, odor boxes, fans, exhaust. And in the end it just didn't cut it and I had to purchase all new equipment.

Unless you are very crafty or mechanibus, then I would avoid this.
Just buy the proper equipment in the beginning and avoid the headache.
It's well worth it.

DIY DWC buckets are excellent though.

I don't want people to get sucked into all the false claims. Cultivating marijuana can be simplified. Many new growers tend to over complicate things.
