Everything you need to harvest 10 oz. of dry material every 3-4 months!
I will list the items that are absolute mandatory to grow first. There is a list with additional items, that I deem useful below. Get started on your first grow tent!
- Your grow medium of choice is soil.
- You grow in a grow tent.
- You start from seed.
- You are a grow enthusiast who wants to make the most of a given space.
- You do not have to run this hobby on a budget. (Options for that below)

- Tents are great to keep control of every aspect. You can change temperatur, brightness, humidity and even simulate seasons in there! Its absolutely necessary to get your tent completely dark to your needs. If you have a closet or a room where you can manage to create pitch black darkness, you dont need a tent. The brand of the tent does not really matter.
- Light: Your articficial sun. Good growlights are hard to find in the LED jungle. Read more about lights below.
- Pots: They come in different varieties. Plastic, fabric, with holes in it from 0.5 to 30 gal. I choose the airpots, because they let air move through the soil, and roots are pruned naturally at the outlets, preventing root rot or rootbound plants.
- Soil: Do not buy common gardening soil. Cannabis roots need space to roam. Specialized cannabis soil has the right consistency and is often perfectly balanced with nutrition. You can also cook your own soil!
- Nutrition: Personal opinion about nutrition – as long as its marketed for cannabis and does not kill your plants every brand seems legit. It is more like a personal decision what kind of nutes you use…
- Ventilation: Moving air prevents bud rot and keeps the branches moving. That creates resistance and your plant will grow thicker and stringer. Keep the vents on 24/7.
- Filter system: Your main exchange for air. If you have to grow stealthy or at home you do not want to have the smell leave the tent. Get one of these asap.
- Clima Control: Really important to keep track of your values in there. You want to know the numbers. Once you know its over 34°C in your tent all the time, you know its time to do something about it. Same with humidity.
- On/Off switch: Over the course of 100 days of a grow you dont want to hit the switches twice a day at the same time. Automate that.
Yes, the light is the most expensive item in a grow operation. Yes, you can save money on light, but this is the best option for a grow room of that size. Its cool, quiet and runs damn bright. It has the most recent technology behind it and does not need extra cooling. But there are alternatives.
PRO TIP: You need at least 35W/ft² of high quality LED/COB light or at least 50W/ft² if you use CMH/HPS lights, if you want max out the tent potential! There are thousands of options. Just make sure its a grow light. Spectrum, PAR, PPFD values and color of light are also important properties. Read everything about the theory behind light here.
Alternative 1 – The Quantum Board
Horticulturelightinggroup.com has a very decent 320 Watt kit. It has alot of advantages like better light distributions or overall efficiency. I just did not link it as first option because it only has 320 Watts, and we wanted to get the most of our room with the given conditions. If you are able to build these lights yourself with a kit, buy these! The magic behind Quantum boards are LM56c or LM301b LED chips from Samsung. If you can find other distributors using these chips, you can go for it.
Alternative 2 – Other LED Distributors
Its true, Timbergrowlights is just an option when in comes to LED lights. There are several chips out there that are awesome to grow weed with.
Timber makes use of Citizen CLU048, Cree CXB3590 and Vero29 COB LEDs. But other companies do it aswell!
Cobshop.net has a 3×3 kit including 4 COBs for $480, but they dont disclose how many Watts you get in the end. I assume its 200 W, so only half of my first option.
Alternative 3 – Low Budget only
I will list them here only because they work. But do not expect wonders. Im talking about the infamous blue/purple or pink lights you find on amazon.
NO, they almost NEVER deliver the amount of power they have in their names, NO you dont need just one, but at least 3 of these “300W” varieties you find online. Which one you take does not really matter, they are all ok. They only use the cheapest LED technology, including chips and drivers. If you spend $210 on three of them, you will be able to light up your tent properly. But remember to tune up the ventilation system, because three of these bad boys run pretty hot in a 3×3.
Alternative 4 – HPS lights
A 600 W HPS light will get you pretty far in a tent like this. And it costs only $130. This can reduce the inital cost significantly, but keep in mind that these light run HOT. And by that i mean shit-i-might-need-an-AC-in-my-tent HOT. The price is low, but running this shit can cost you! Save some money, ditch the AC and the pay only 2/3 to run a sweet LED light in there and pay less for your production.
Alternative 5 – Build your own COB or Quantum Board light
www.ledgardener.com, is the best source for that. There will be a guide here soon….
Soil and nutrition – Globalization and availability
If you live in Europe you have different soil companies than in the US. So while you can buy BioBizz in Europe pretty cheap, it is better to choose Fox Farm.
The right soil is very important for your grow. Your roots want a pretty loosy, oxygenated environment. Many soil companies put peat (turf) in their soil which is very harmful to the environment. Check the ingredients, if you want to save the planet.
EU soil recommendations
US soil companies
Same with as soil. It seems like there is a new nutrition company out there every week. Even the breeder try to jump on the nute train and handing out their own nutrition along the seeds. (Royal Queen Seeds and Green House Seeds for example.)
I will also only recommend nutrition that have an organic base. I just do not believe in chemicals, but thats up for discussion.

There are a lot more items making your tent easier. These are nice to have, but not 100% necessary. This list is not not yet completed.
- Depending on your method of germination you will need papertowels or kitchen paper.
- Since germination needs a dark, moist and warm environment, you might need a propagation box. I just put them in an old cookiebox on my PC.
- Do not touch seeds! Use a tweezer.
Seedling and vegetative stage
- Seedlings do not need flooded with water. Use a pump sprayer and be careful!
- If you plan to train your plants, you need gardening wires or metal stakes. Or anything else you can come up with. You can also just use a cord and bind them down.
- Use sharp scissors, knifes or even scalpels to cut leafs!
- If you see pests like mites or thripes, treat them with bio degradable organic insecticide. Be careful with that!
- Some genetics produce fat buds. Too fat to hold them in place. Use plant yoyos or bamboo sticks and wire to hold them in place.
- If you see any pests in the flowering stage do not spray the buds with insecticide. Use predatory bugs to fight them. This is your chance to have a personal ladybug army in your garden.
- Jewelers loupes help you watching the trichomes and help to determine the harvest window.
