Romberg Greenhouse Maximus Complete LED – Heated Propagator with Integrated Grow Light

The Romberg Greenhouse Maximus Complete LED combines bottom heat, LED plant lighting, and adjustable ventilation in one unit. It creates a stable environment for seeds and cuttings even in darker rooms or during short winter days.

A 5 W Venso LED lamp provides a plant-friendly light spectrum, while the heating mat keeps substrate temperatures in the 22–25 °C range under normal room conditions. Together they support strong, compact growth from sowing to transplant.

More information

Integrated LED lighting: 5 W lamp for seedlings and young plants when natural light is limited.
Heated base: built-in mat maintains a stable, warm root zone.
Adjustable vents: lid sliders let you regulate humidity and air exchange.
Compact footprint: approx. 59 × 27 × 39 cm – fits on shelves or sideboards.
Durable housing: anthracite body that is easy to clean and resistant to common horticultural acids.

Use the Maximus Complete LED for reliable germination and propagation performance without relying on window light alone.

Ventilation and humidity in Greenhouse Maximus Complete LED

Closed start: Keep vents mostly closed for rooting and germination, then open gradually to harden off.
Condensation: Light condensation is normal; persistent heavy droplets usually mean it needs a little more airflow.
Watering: Aim for lightly moist media rather than saturated trays.

Cleaning and storage for Greenhouse Maximus Complete LED

Wash between rounds: Rinse tray and lid with mild soap, then dry fully.
Gentle cleaning: Simple cleaning keeps plastics clear and seals intact.
Storage: Store out of direct sun and heat so the lid does not warp.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
