To place an order, add products to your cart and proceed to checkout. Enter your address and choose the payment method that suits you. Confirm the order, and you will receive an order confirmation or instructions via email if you choose, for example, Crypto payment or bank transfer. You can also place an order via the chat available on the website, by phone, email, or in person at our store in Katowice. We are available on Signal, Telegram, and WhatsApp.
Fill out the return form, download it, or use a form that clearly states the order number, product name, bank account number for the refund, email address, and phone number. The return address is included in our form.
Paczkomat, like some couriers, is only available for certain sizes and weights of products in your cart. If you don't see this option, one of the products exceeds the size or weight limit for Paczkomat. Remove it from the cart, and the shipping option will become available. We are currently working on a module that will indicate which product excludes Paczkomat or other carrier options.
Yes, our priority is discreet shipping. We do not use domain names on labels. When choosing DPD or Paczkomat InPost, you are guaranteed that the package is not marked with our address as the sender. The sender's name is completely different and does not raise any suspicions—we use intermediaries. All packages are wrapped in black stretch film, and there is no way to guess what is inside. We do not use tapes or any other store symbols on the packages.
II. Indoor Cultivation
1. Growbox - Grow Tents
A growbox is a tent used for growing plants. You can hang a grow light inside, connect ventilation, and it provides light-tightness, good light reflectivity, and ensures that light does not escape outside.
The best options are RoyalRoom tents. This is a Polish brand that matches the best Western products while offering the lowest price. A typical tent for beginners is 60x60x160 cm. It is enough for up to 4 plants, and the height is also suitable to comfortably fit everything. All tents smaller than this require more effort for cultivation.
You need to ask yourself how many plants you want to grow. Use this rule of thumb: for one plant, you need at least 20x20 cm, optimally 40x40 cm. Consider the size of the pot and the strain. For a 120x120 cm tent, the standard is 5-6 full-season plants in 18L pots or 6-9 autoflowering plants in 11L pots. For a 60x60x160 cm tent, the standard is 1 plant in a 20L pot or 4 plants in 11L pots. Anything in between is fine.
Yes, you can build a growbox yourself. However, consider whether it is worth the effort. Today, the prices of tents are really good. Tents can be folded and unfolded any number of times, are easy to use, and provide protection against unwanted odors and light leaks. Often, DIY projects, such as converting a cabinet, are not airtight—unwanted odors escape, and light leaks out. They cannot be folded or unfolded, are heavy to move, and require a lot of work: drilling ventilation holes (at least 100 mm and at least two), lining the entire structure with foil, and creating holes for power cables.
2. Indoor Lighting - HPS and LED
Currently, LED lighting dominates the market because it is more energy-efficient. It is usually Plug & Play, so it does not require additional connections to power supplies, which in the case of HPS are often placed outside the tent. LED lighting is also affordable today and solves the problem of excessive heat in the growbox. Additionally, the latest LED chip technologies, such as SMD LM301B EVO, used in lamps like Lumatek or GOAT, ensure the highest quality and yield.
Generally, the minimum power requirement for LED lamps is about 300W per 1m². Below is a quick reference for typical grow tent sizes:
| Growbox Size | Minimum Lamp Power | Optimal Lamp Power |
|---|---|---|
| 40x40 cm | 50W | 80-100W |
| 60x60 cm | 100W | 150-200W |
| 80x80 cm | 200W | 240-300W |
| 100x100 cm (1m²) | 300W | 350-450W |
| 120x120 cm | 450W | 500-600W |
| 150x150 cm | 600W | 750-900W |
Remember that optimal lighting provides better yields but may result in higher electricity consumption.
It's best to use our energy cost calculator: Electricity Calculator. You can accurately calculate how much you will pay for using lamps in your cultivation by entering the lamp power, operating time, and price per kWh.
Currently, the best lighting has a color temperature between 3000-3600K. Most modern lamps have this color temperature.
Regular bulbs are not suitable for growing plants. Compact fluorescent lamps are better but require at least 100W per plant. The cost of such lamps, along with reflectors, sockets, and lamp preparation, is completely unprofitable compared to affordable LED lamps, such as Cosmos or better GOAT 100W.
LED lamps: about 40-60 cm from the tops. For HPS, slightly higher. Adjust the lamp distance during cultivation—if the plants are not burning or the tips are not curling, the distance is appropriate. If the plants are stretching and drooping, the light is too weak or too far away.
Yes, it is a basic product that you must have. Only a timer ensures proper lighting operation and healthy, unstressed plants.
3. Ventilation
The foundation is an exhaust fan (duct, axial-duct, radial, or centrifugal). Next, a mixing fan is important, followed by an intake fan. When using the latter, remember that it can lead to a loss of negative pressure in the tent, which may cause unwanted odors to escape. Also, remember the ventilation ducts!
All the time! The exhaust fan ensures air exchange, removes humidity, and prevents plant rot. It must run 24/7!
It is not essential but very useful. It reduces the risk of rot, especially during the flowering phase, and ensures better plant respiration.
4. Carbon Filters and Odor Neutralization
Yes, if you want to eliminate odors during cultivation. They remove 98% of odors.
Prima Klima, also consider adding a second filter inside. We described this in the article: How to effectively eliminate the smell of marijuana.
5. Controllers and Timers
Yes, absolutely. Manually turning the lamp on and off is not practical and is time-consuming. Timers are very affordable and indispensable!
Standard for full-season plants:
Vegetation: 18h light / 6h darkness
Flowering: 12h light / 12h darkness
Autoflowering:
Vegetation: 18h light / 6h darkness
Flowering: 16h light / 8h darkness.
6. Growing Mediums
The simplest and most effective method is to use Eazy Plug trays. See the tray. Just insert the seeds into the holes after watering the tray. This method ensures the highest germination success rate.
Opinions are mixed, but in our opinion, for hard-to-germinate seeds, boosters slightly speed up the process and ensure simultaneous germination.
No, regular lightmix is sufficient; you won't see any difference.
Rockwool cubes, such as Grodan, work best.
Yes, but rockwool significantly delays germination.
The standard is 10-18L, depending on the length of the vegetation period and the space in the room. Remember, the larger the pot, the larger the plant can grow.
From 7 liters to 18 liters.
It cannot be definitively stated; both types have their pros and cons. The advantage of fabric pots is more even drying of the soil, which better prevents root rot. However, the thin material of some pots makes watering difficult, as water spills out the sides before reaching the bottom.
It's not necessary, but it helps prevent root rot from overwatering, especially for beginner growers.
No, it can hinder water evaporation from the pot and be harmful.
Yes, it's worth adding perlite to the medium. Ready-made mixes available in our store already contain perlite.
No. You will get the same yield. Coco coir works better in autopots and can be reused. However, the start is usually slower. Be cautious with BIO nutrients when growing in pure coco—they can sometimes rot. For beginners, we recommend soil or a soil-coco mix.
From 30-50% coco coir. It loosens the soil and prevents it from compacting easily. This is a good cultivation method.
In most cases, NO. LightMix soil works best. If you don't fertilize during vegetation, you can use richer mixes, but they require more experience and pH/EC meters, as they can cause issues. If you're a beginner, LightMix is the best choice.
7. Other Questions About Indoor and Outdoor Cultivation
No, you don't. If you're a beginner, focus on a good tent and lighting. Then, take care of the necessary accessories, followed by nutrients, and only then consider CO2.
Cultivation takes an average of 8 to 14 weeks. For autoflowering plants, it is usually 8-12 weeks. For manual strains (full season), depending on the length of the vegetation period, the average cultivation time is 10-14 weeks.
It is definitely harder to achieve very high quality with outdoor cultivation. Although outdoor can yield more, the quality in 95% of cases will be better under lights.
