Is one light sufficient?

[Finnicki]

I have a 3x3x6’ tent. I am starting up with two plants after a brief rest. Light is an LED 600 watt, Amazon purchase. I try to keep light 18” from top of plants. Is one light enough? When I couldn’t raise light any higher In the tent as the plants grew, I resorted to using a sheet of parchment paper below light to soften the harshness. Plants didn’t seem to mind. I need to top both this grow.

Does the light tell you the footprint it covers? Also what is actual power draw of the light? In power terms you need 30-35W per Sq ft.

Here is a chart from that light. It’s about 2 years old. Not the updated models. I have two, but have only used one at any time in tent.

I would use both of them in your tent

Thats actually 130w light and they have focused lenses towards the center so they can say the words 600 par, its only 600 par for like 2 square inches.
Thats like a single leaf gets enough light.

You need at least two of those.
