Sf1000 or a ionboard s22 any advice or other Options
2.7 meters? A decent metric for illuminating 2.7 meters square is 40 watts per square foot. You are looking at 17.7 square feet, so 710 watts is a required minimum for optimal results if you intend to populate the whole grow space.
The SF1000 is built with quality components, but it is only a 100 watt light that will struggle to flower even a single plant with decent results.
I have a mars 150watt that I ran on my last run it’s did alright…was just wondering if I should switch it up?
I have this exact tent spec and to reach the universal accepted light energy I run 2 150 watt lights.
100 will be enough for one small plant and the flower footprint for good bud will be minimal but it will deliver some bud.
How many plants do you intend to grow?
Run them both. Get a tool and move the panels on a tilt until the light looks flat. With that much light you can rigid mount them up high and change dimmer for ppfd.

Ideally more lighting for 2 plants, but if you want to go for it with what you have. You’ll get a harvest, but the plants will be stretchy and flowers will be larfy. You’ll get far better results with more lighting though.
