XL Height extension sets
There are several reasons why you would use a height extension set, it allows you to utilize different reflectors without the air system getting in the way. It gives you the option of using a more powerful extraction system for higher wattage lamps. You can also choose a height extension set with a seperate ‘growing’ chamber for seedlings or motherplants.
The XL sets (height extension sets) add considerable height to your cabinet. 56cm for the Bonanzas and 37cm for the Wing cabinets. Easy to install.
