Intensive Cultivation 150x90cm: Maximize Your Yields Over 1.35m²

Intensive cultivation on a 150x90cm surface represents the art of getting the most out of a compact 1.35m² setup. This approach demands precise technical mastery: powerful LED lighting, optimized ventilation, and rigorous space management. With the right equipment, this area becomes a true production laboratory where every square centimeter counts.

Why Choose Intensive Cultivation on 1.35m²

The main advantage of this surface area is that it allows for the installation of a truly efficient system without taking up too much space. Frankly, a well-optimized 1.35m² can rival much larger, poorly designed setups. Modern LED lighting easily delivers 400-600 µmol/m²/s over this surface, which meets the needs of quality intensive cultivation.

Ventilation also becomes easier to manage. A 150-200 m³/h extractor is more than enough to effectively renew the air in a 2-3m³ volume. This is where it changes everything: you perfectly control temperature and humidity without the hassle of larger installations. Energy costs remain reasonable, around 200-300W for lighting and 50W for ventilation.

How to Properly Equip Your 150x90cm Space

For lighting, aim for 200-300W of full spectrum LED evenly distributed. 240W quantum boards are perfect for this surface – they cover exactly 1.35m² with uniform intensity. Pay attention to height: keep 30-40cm between the LEDs and the canopy to avoid light burn.

For ventilation, a centrifugal extractor of at least 150 m³/h with a suitable carbon filter. Don't forget passive or active intake depending on your setup. The ideal temperature is between 22-26°C during the day, 18-22°C at night. Humidity should gradually decrease from 70% during growth to 40-50% at the end of flowering.

To maximize space, consider SCROG (Screen of Green) or LST (Low Stress Training). These techniques allow you to fit 4-6 medium plants or 2-3 large ones on the surface. The important thing is to maintain a uniform canopy at 60-80cm in height to optimize light penetration.

Frequently Asked Questions

Which 150x90cm LED lamp do you recommend for intensive indoor cultivation?

For intensive cultivation on 1.35m², opt for a 240-300W full spectrum quantum LED panel (3000K-6500K). Samsung LM301B or LM301H models offer an efficiency of 2.7-3.0 µmol/J, ensuring a PPFD of 400-600 µmol/m²/s across the entire surface. Avoid low-end purple LEDs that generate too much heat and consume more power. The optimal hanging height is between 30-45cm depending on the chosen power.

How many 1m tall plants can I put in a 150x90cm tent for intensive cultivation?

With 1m tall plants, count a maximum of 4 plants in 11L pots for successful intensive cultivation. This density allows each plant to properly develop its lateral branches without hindrance. If you master SCROG training, you can go up to 6 plants in 7L pots, but regular pruning and training will be necessary. The minimum spacing between pots should be 15-20cm for air circulation.

What ventilation and extractor should I choose for a 150x90cm grow box without light leaks?

For a 1.35m² grow box with a height of 2m (volume 2.7m³), a 150-200 m³/h centrifugal extractor is perfectly suitable. Prefer models with a dimmer to adjust the flow rate according to the cultivation phases. For intake, passive 125mm grilles are sufficient, or a 100 m³/h intake fan if you want total control. To avoid light leaks, install anti-backflow elbows on all ducts and check the seal of the connections with aluminum tape.

How to set up a 150x90cm grow room in a small space without odor?

Installation in a small room requires particular attention to the filtration system. Use an oversized carbon filter (200-250 m³/h) compared to your extractor to guarantee zero odor. Place the grow box away from heat sources and allow 50cm of space around it for maintenance. Air can be exhausted to the outside via an insulated duct, or recirculated into the room if it is larger than 15m². Pay attention to the ambient temperature: it should not exceed 25°C, otherwise your grow box will overheat.

How to maintain and clean a 150x90cm tent after intensive cultivation to prevent mold?

After each harvest, completely disassemble the setup and clean the tent with a 3% hydrogen peroxide solution or 70% isopropyl alcohol. Pay special attention to corners and zippers where moisture accumulates. Let it dry for 24 hours with windows open before reassembling. Also clean pots, saucers, and supports with the same solution. Systematically change carbon filters every 12-18 months and dust off LEDs with a dry cloth. This routine prevents 90% of mold and pest problems between grows.
