R420R Hydro, Twin



The Maxspect R420r (Razor) contains advanced technology that allows you to control the time the sun rises and sets in your grow room in the same way that nature intended. There is also the bonus of no need for plug in timers anymore. The light is fully controllable over 2 channels with increments of 1%. One channel is matched for growing your plants and seedlings saving even more energy as the unit can run on minimum power whilst the other channel can also be deployed during the flowering stages customers can mix and match each of these channels for different intensities or blends of each spectrum to suit the fruit that they are growing.

1 x 180W R420R will light a 1.2m x 0.6m area. We recommend that 2 x R420R units are used in a 1.2m x 1.2m grow tent and will produce similar results to a 600w sodium bulb.

A pair of R420R units running at full power over 4 x harvests in a 12 months period will cost no more than £225 in electricity however if you are only deploying half power during growth periods this will be reduced significantly further. 

The R420R is perfect for use in a tiered system for multiple small plants per layer — using this format it is possible to grow 2 or 3 different species in the same grow tent.

The R420r comes with a built in programmable lighting cycle.

The end user can program their R420r to automatically turn on and off at set times of the day no need for separate timers!!! The unit can also run at different intensities for example if you want to run with 80% power on the A (Blue dominated) spectrum and 40% on the B (Red dominated) spectrum simply input this data into the controller and the light will automatically come on at your chosen time point with this blend of light, giving you total control of the lighting intensities within your growing environment.
