How the Secret Jardin Twin T90 Runs Two Stages at Once
Two rooms on a single floor tile. Assembled, this tent measures 36 in wide by 36 in deep and stands 87 in tall, split into a 63 in upper chamber and a 24 in lower one. The upper room takes a flowering light and full-size plants; the lower shelf runs cuttings, seedlings or a mother under something small. Each tube carries 30 lbs and the tent as a whole takes 60 lbs. Walls are 190D hammered mylar at 95% reflectivity, with Level 2 light proofing. A thermally isolating panel splits the chambers so the photoperiods never bleed together. Both chambers are washable inside and out.
Where the Dark Room Twin 90 Earns Its Floor Space
The Dark Room Twin 90 answers one specific problem, which is running a perpetual harvest when there is only room for a single tent. Cuttings root downstairs while the previous batch finishes upstairs, and the handover is a matter of opening two zips rather than moving between rooms. Each chamber needs its own extraction, which is the part people underestimate. The lower shelf will cook behind a closed zip without air moving through it. Polypropylene corners and a divided frame keep the whole thing tool free to assemble. The lower chamber is short enough that it only suits propagation and mothers kept low. Anyone wanting two full flowering spaces should take two separate tents instead.
Key Features
- Two sealed chambers: A tall flowering room over a short propagation shelf, running independent photoperiods.
- Three foot footprint: The whole perpetual cycle fits the floor area of a single small tent.
- Thermally isolating divider: Keeps light and heat from the upper chamber out of the cuttings below.
- 190D hammered mylar: 95% reflective walls with Level 2 light proofing on both chambers.
- Thirty pound per tube rating: Sixty pounds across the tent, stated so the hang plan is a calculation rather than a guess.
- Washable inside and out: Both chambers wipe down between turns, which matters more when propagation is in the building.
