TRIPLE B features five 5gal (20L) white buckets with five CFL bulbs(4100K and 6500K) and two 8 mm PC fans. Customized and friendly, TRIPLE B operates in a lightproof closet. Slightly cold during winter, lighting generates fortunately enough heat for the grow space (over 75°F/24°C inside). A red adhesive tape is used in order to highlight where TRIPLE B can be safely handled. This amazing Space Bucket was made thanks to the resources of the Spacebucketer community and especially Ekrof builds.
