Indoor Grow Kit 600W Without Tent – Complete Set for Room Growing

Turn any spare room, closet, or corner of your house into a high-performance production center with the Indoor Grow Kit 600W Without Tent. If you already have the physical space and want to save the cost of a cabinet to invest in pure power, this set is exactly what you need to start harvesting professional-grade buds from the very first cycle.

Is your spare room gathering dust instead of resin?

You probably have a space at home—a pantry, a built-in wardrobe, or a small spare room—that is perfect for growing, but you don't know where to start. You look at the empty space and think about the potential, but the idea of buying a tent that doesn't fit the measurements holds you back. You want to grow, but you feel limited by standard kits that force you to buy a structure you don't need.

It is incredibly frustrating to spend hours browsing forums and shops, trying to figure out if that extractor is powerful enough for that 600W bulb or if the cables will be compatible. In the end, you waste time, spend more money on shipping from different places, and risk setting up a system that overheats or doesn't perform. The result? A headache instead of a harvest.

The Indoor Grow Kit 600W Without Tent is the definitive solution to cut to the chase. We have selected and tested every component to work in perfect harmony: lighting, ventilation, and nutrition. You just have to prepare your room and plug it in. Forget about compatibility math; we've already done it for you so you can focus on what matters: growing huge plants.

Why this kit improves your DIY setup

Unlike buying loose parts, this kit offers you a synergy verified by experts. The 600W HPS lighting is the "gold standard" of indoor growing; it offers a light intensity that penetrates to the lower branches, guaranteeing heavy and dense flowers, something that low-power LEDs cannot always achieve in large spaces. By removing the tent from the equation, you have total freedom to adapt the crop to the shape of your room, maximizing every available square centimeter.

Plus, you're not just buying lights and fans. We include a complete pack of Cannabis fertilizers from Biobizz, ensuring that the flavor of your harvest is 100% organic and free of chemicals. It is the perfect balance between the raw power of HPS and the finesse of organic cultivation.

Key features you’ll notice from the very first grow

• 600W HPS Powerhouse: Includes a Class 2 ballast, a high-reflection granulated reflector, and a Hortilight bulb. This combo mimics the autumn sun, triggering explosive flowering and rock-hard buds.
• Double Ventilation System: A 150mm extractor for heat removal and a 100mm one for air intake (or support), connected by 5 meters of Aluconnect ducting. Goodbye, heat pockets.
• Organic Nutrition: The Biobizz Try-Pack (Bio Grow, Bio Bloom, Top Max) covers all phases. You will get sticky, aromatic flowers with a smooth throat hit.
• Total Control: Includes a VDL digital thermohygrometer with a probe to monitor the climate at the tips of your plants and a Cornwall mechanical timer to automate the photoperiod.
• pH Precision: A drop test kit and pH Down Dry ensure your water is always in the sweet spot for nutrient absorption.
• Adjustable Height: Easy Roller pulleys allow you to raise the lamp as your plants stretch, keeping the lumens exactly where they need to be.
• Top Genetics: We include 5 PEV Seeds of your choice so you can start with vigorous and reliable strains.

Who this product is especially interesting for

This kit is a master move for specific grower profiles:

• The "Handyman" Grower: If you are handy and can adapt a room with Reflective material for grow room, this kit gives you the engine for your custom Ferrari.
• Budget-Conscious Yield Hunters: You want the maximum gram-per-watt ratio without paying for a structure (tent) you already have in the form of a closet.
• Old School Lovers: For those who know that, despite modern tech, a 600W HPS is still the king of production/price ratio.

How to integrate it into your routine without overcomplicating things

Setting this up is easier than IKEA furniture. Since you don't have a tent, the first step is to ensure your space is light-tight (no light leaking in during the dark period) and line the walls with reflective plastic or white paint to not waste a single lumen. Hang the HPS lamp using the Easy Rollers from the ceiling or a sturdy bar.

Connect the 150mm extractor at the top of the room (heat rises) and the 100mm one at the bottom for intake. Program the timer for 18/6 in growth or 12/12 in flowering, and you're set. With the Biobizz pack, follow the simple table included; being organic, it is very difficult to over-fertilize, making it ideal for a stress-free crop.

Frequently Asked Questions

What area does this 600W kit cover?

This kit is optimized to cover a growing area of approximately 1.20 x 1.20 meters (1.44 m²). If your room is larger, you can focus the light on that area or add more kits.

Does the HPS light consume a lot of electricity?

A 600W HPS is powerful. You can expect a consumption similar to a small electric heater. However, the return on investment in terms of dry flower weight is usually superior to other cheaper lighting systems.

Is it difficult to install without a tent?

Not at all. The only difference is that you have to screw the pulleys into your ceiling or a beam instead of the bars of a tent. The rest (connections, timer, irrigation) works exactly the same.

What do I do when it's time to harvest?

Since you have a dedicated room, you can use the same space. We recommend checking our section on Harvesting and Drying Marijuana to use drying nets or hang the plants directly using the ventilation system to avoid odors.

Personal Experience of Pevgrow’s CEO (Alan)

"Before grow tents became the standard, we all started like this: clearing out a closet or a spare room and hanging a 600W HPS. Honestly? There is something special about walking into a room dedicated entirely to your plants, without zippers in between.

I love this kit because it brings back that 'old school' power. The 600W HPS bulb generates a heat that, if managed well with the extraction included, accelerates the metabolism of the plants incredibly. The buds come out hard as stones. If you have a cool room or live in a not-too-hot climate, this kit is unbeatable in production price. Plus, the Biobizz touch guarantees that, despite the high production, the flavor remains gourmet. It's the setup I recommend to my friends who have a spare room and want to fill the pantry for the whole year in one go."
