Komplette HPS Growzelt-Kits

A complete HPS grow tent kit bundles the tent, ballast, reflector, lamp, extraction fan, carbon filter and ducting into one matched purchase. HPS has been the flowering standard for decades and remains the cheapest route to serious light output per pound spent.

What is in a kit

• The tent in a footprint matched to the lamp – typically 100 x 100cm for a 400W, 120 x 120cm for a 600W
• Ballast, reflector and lamp – digital ballasts on our kits, dimmable on most
• Fan, carbon filter, ducting and clamps sized for the heat the lamp actually produces
• Hangers and a timer

HPS or LED?

HPS costs less up front and its flowering spectrum is proven over a very long time. Against that: it runs hot, so you need more extraction and you will feel it in summer; lamps degrade and want replacing roughly annually; and running cost per gram is higher. LED wins on heat and efficiency, HPS wins on purchase price and familiarity. If the room is in a loft or a small bedroom, heat usually decides it – see complete LED grow tent kits.

Extraction matters more with HPS

A 600W lamp is 600W of heat inside a sealed box. Size the fan generously, run a decent carbon filter, and consider a fan controller so you are not running flat out at night. Browse extraction fans for the range.

Building instead

If you would rather choose each component, tent kit builder parts covers the hangers, ducting and clips, and grow room lights covers ballasts and lamps separately. Every kit we sell is on grow tent kits.
