How it works

Three steps, whichever door you pick

Grow Tent Builder

  1. Step 1: Pick a tent or a complete kit

    Everything listed is in stock. Add your floor and ceiling and we only show tents that fit the space.

  2. Step 2: We fill in the rest, with the why

    Light by PPFD, fan by CFM and duct size, a height check, climate, pots, soil and feed — each pick shows its rule and the math.

  3. Step 3: One cart, or a grower

    Add it all to your cart in one tap with 10% off, save and share the build, or have a grower in Milford or Webster look it over.
