An HPS complete kit has been a classic in indoor growing for years. The powerful high-pressure sodium (HPS) lamps deliver a bloom-boosting light spectrum that optimally supports your plants during the flowering phase. A complete kit includes all the important components – ballast, reflector and HPS bulb – perfectly matched and ready to use straight away. Whether in a grow tent or a professional grow room, HPS systems are robust, reliable and deliver high yields with dense, heavy flowers.
An HPS complete kit is the quickest way to a working grow light: lamp, reflector and ballast in one box, matched to each other. Here you'll find 600W kits from Platinum, with or without dimming, and 600W kits with a Pro Reflector Wing in Medium or Large size. A 600W kit is a good fit for a 100x100 or 120x120 cm tent. A dimmable kit lets you start flowering at lower power and adjust to your climate. Remember to plan extraction for the extra heat; extraction fans help here. Spare bulbs are in 600W HPS lamps.
Questions & answers about HPS Complete Kits
All growing questions →- Lighting LED or HPS: which grow light is better? LED, for most people with a tent. It's more efficient, makes less heat and the diodes last years. HPS costs less to buy but needs more ve... Read the answer →
- Lighting How many lumens does a grow room need per square metre? None, really. Lumens measure what your eye sees. Plants use PPFD, in µmol/m²/s, so compare lamps on that. Read the answer →
- Lighting How many hours of light do plants need in veg and in flower? Photoperiod plants usually get 18 hours on and 6 off in veg, then 12 on and 12 off to flower. Autoflowering plants can stay on 18/6 or up... Read the answer →
- Problems & pests What is light burn and how do I stop it? Light burn shows as bleached, yellow or crispy leaves at the top, closest to the lamp. Raise the lamp or dim it. Read the answer →
Advantages of HPS Complete Kits
An HPS lighting system brings a number of advantages:
Complete & ready to go: all parts such as lamp, ballast & reflector in one package. Proven technology: HPS lamps have been the standard for the flowering phase for decades. Bloom-boosting light spectrum: supports a lush harvest with heavy buds. Excellent value for money: cheaper than many modern alternatives. Compatible: suitable for various grow tent sizes and setups.
Structure & Components of an HPS Complete Kit
A typical HPS kit consists of three main components:
1. HPS Bulb
High-pressure sodium lamps with a high red content in the light spectrum – ideal for the flowering phase.
2. Ballast
Regulates the power supply and ensures safe operation of the HPS lamp.
3. Reflector
Distributes the light evenly in the grow tent and maximizes light output.
Optionally, kits can also include dimmable ballasts or optimized reflectors, allowing even more flexible adaptation to the needs of the plants.
Use in Indoor Growing
HPS complete kits are particularly suited to medium and large grow tents. Because of the strong light output, good ventilation is needed – ideally combined with duct fans, carbon filters and air circulation systems. Many growers use HPS kits specifically for the flowering phase, while LED or MH lamps are used during the growth phase.
