Choosing the Ideal LED Lighting for Your Indoor Growing
Choose the ideal lamp according to the size of your grow tent
Lighting is the key to success in indoor growing. Without sufficient natural light, plants rely entirely on horticultural lamps to grow, flower, and produce fruit. But with so many models, powers, and spectrums, it is easy to get lost. This detailed guide will help you make the right choice according to your space, goals, and budget.
Criteria to know before choosing your lamp
- Recommended PPFD : 400 to 600 µmol/m²/s for growth, 700 to 1000 µmol/m²/s for flowering.
- Light spectrum : Blue (growth), red (flowering), or full spectrum.
- PAR : The entire photosynthetically active spectrum (400-700 nm).
- Coverage area : each lamp has an ideal zone to respect.
- Lamp-plant distance : to be adjusted according to power and model (see each datasheet).

Small budgets: tips to light without breaking the bank
If you are a beginner or have a small budget:
- Use consumer LED bulbs (cool white for growth, warm for flowering).
- Recycle T5 bars or neon lights with an adapted spectrum (6400K for growth).
- Optimize reflection with mylar or a white surface to concentrate the light.
- Gradually add modules like Cosmorrow or TNoled for growth phases or seedlings.
Summary: choosing the right lamp = successful cultivation
Choosing a grow light is not just a question of watts. It is a balance between:
- the right power for your area,
- a spectrum adapted to each phase (growth and flowering),
- a well-distributed PPFD over the canopy,
- and above all durable and well-designed equipment.
