The Photoblaster uses LED lights in a 3:1 Red to Blue light ratio. This is common in growing applications. However, this makes plants appear black or grey, making it impossible to assess health. To remedy this, we added full spectrum white light to the mix. Additionally, light outside of red/blue have been implicated in signalling responses in plants (review coming soon).
Adjustable, Stackable, Uniform, Optimized
Climate-controlled growing space is often limited. The Photoblaster allows vessels to be stacked vertically. You can easily fit 9 vessels in 1 cubic foot. Connecting the boxes is easy – the power cords can be daisy chained from one LED light to the next (see picture).
Control your cultures
Included dimmers can control light intensity from 10 to 150 μmol/m²·s.
The standard light intensity for plant tissue culture is 40μmol/m²·s – why? It’s likely because that’s about the intensity you get from a fluorescent bulb or two. Plants have a variety of growth conditions, some excel only in low light (ex. Acer saccharum) while other thrive in high light (ex. Artemesia annua). Are you cultures getting enough, or too much, light?
The Photoblaster offers superior uniformity due to its distance from the plants. Overhead lighting setups (especially fluorescent tubes) are extremely non-uniform. See Figure 1 in Shukla et al 2017.
Reduce electricity consumption
Like all LEDs the Photoblaster is efficient, using only 2W of power to deliver 150μmol/m²·s at the maximum setting. Such low energy requirements are an advantage of having the LED lights on the top of the vessel. This also reduces waste heat production in culture rooms.
