Choose the Ideal LED Lighting for Your Indoor Cultivation

Choose the Ideal Lamp According to the Size of your Grow tent

Lighting is the key to success in indoor cultivation. Without sufficient natural light, plants rely entirely on horticultural lamps to grow, bloom, and produce fruit. But with so many models, powers, and spectrums, it's easy to get lost. This detailed guide will help you make the right choice according to your space, goals, and budget.

The 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 spectrum of photosynthetically active radiation (400-700 nm).
• Covering surface : each lamp has an ideal area to respect.
• Distance lamp-plant: to be adjusted according to power and model (see each sheet).

Small budgets: tips for lighting up without breaking the bank

If you are starting out or have a small budget:

• Use consumer LED bulbs (cool white for growth, warm for flowering).
• Recycle T5 bars or neon lights with an appropriate spectrum (6400K for growth).
• Optimize reflection with mylar or a white surface to concentrate light.
• Add modules gradually like the Cosmorrow or TNoled for the growth phases or for seedlings.

Summary: choosing the right lamp = succeeding in your cultivation

Choosing a grow light is not just a matter of watts. It’s a balance between:

• the right power for your surface,
• a spectrum adapted to each phase (growth and flowering),
• a well-distributed PPFD over the canopy,
• and especially a durable and well-designed material.
