The Caboose is a famous Californian cut, a cross of the original Trainwreck with the legendary Salmon Creek Big Bud. After several years testing Strain Hunters were able to reverse it and self it, to make stable feminized seeds. The strain grows compact, with short internodes and wide branching.
 The structure of the branches makes it a good filler and a great producer; it has the irregular bud formation typical of the Trainwreck heritage, with the calyxes large and round, with purple and reddish hues, but the buds grow large and dense, more like a big Bud than a Trainwreck. This large-calix and large-bud combination is very rare and makes the Caboose an ideal commercial strain with great quality and a very complex aroma and scent.  The Caboose is good for outdoor and indoor and performs great on all mediums. If plants are large the branches should be supported. The Caboose is a fast hit, has a distinctive mineral aroma, complemented by a flowery background. It smells like Chinese oranges and spring blossoms, but it also has a pungent, almost metallic scent (a memory of the NL heritage from the Big Bud side).  The resin is very white, giving it a really cosmetic look.
