Tips?

New to vert. I plan on using my 400 watt hps. 4 plants. Any advice for beginers?

Place a fan directly below light blowing up to control heat and chicken wire/mesh between plants and light so you can SCROG. You can shape the mesh into a cylinder and wire tie it to hold its shape. Spacing between the light and mesh can vary but if it's the first run I'd allow for about a 12 inch gap. This is so you can train the plants around the light to create a nice even canopy maximizing your yield. No cool tube needed as that will significantly reduce the light intensity/yield.

thanks a lot!

Not a problem....vids are also a very helpful tool whenever you want instant info/solutions.

What he said! Good advice bush,,, short and to the point.

Thx...just trying to help someone in need and not add to the confusion. We all need help at some point and I just wanna do my part to show my appreciation...thx RIU!

I concur with all the above. Try to hang your light about two thirds the way up the plant, raising it as the plant grows.

And/or add a second light.

Or put it on a mover.
