After several years testing we were able to reverse it and self it, to make stable feminized seeds. The strain grows compact, with short internodes and wide branching. The Caboose is good for outdoor and indoor, and performs great on all mediums. If plants are large the branches should be supported. The EC levels can be high, especially when the plants are in a healthy environment and perform at 100%. 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 flavour.Height: short plant (average internodal distance under 5 cm).Flowering Indoor:8 weeks flowering time. Up to 0.9 gram (dry and manicured) per watt per m2 (with 1000W HPS).Flowering Outdoor:8 weeks flowering time. Very large plants can harvest over 1Kg of dried, manicured buds.Taste (burned): chemical, mineral, flowery.Scent (unburned): kushy, sweet like blossoms yet salty, almost metallic. Complex.What the dried bud/crumbled bud looks like: The dried buds are dense, thick and hard, with large calyx. The crumbled bud is very sticky, bright green with some orangy-brownish hues.Effects: Speed of high onset: fast hitter.Duration of high: medium lasting.Quality/type of high: strong, far more stoned than high, trippy first and then sedative. Medicinal qualities: still to be evaluated, surely a good appetite stimulant.
