Hydroponics: Growing Marijuana in 2018

Growing outdoor will leave your plants at the mercy of environmental circumstances and mother nature – for the better or for the worse. With an indoor hydroponic production on the other hand, you are in charge. Creating a grow room will allow you to influence all factors that limit or accelerate the growth of our plants, and master the art of maximize yields and return on your investment.

From choosing the best grow lights to deep water culture, from fans to wall paint – we've got you covered. You need to understand that setting up the infrastructure for hydroponics might take more time and investment at the start but can produce yield levels otherwise impossible to reach.

Planning Your Business

As with any business, start by reflecting on why you want to do this. What's in it for you? What are your reasons for getting started (financially, professionally and emotionally)?

Research the market circumstances and legal considerations in the area you plan to operate. Your business will be very different depending on your goals: Do you want to grow medical marijuana or recreational? At what scale? And in what state?

What will your team and setup look like? How many people will be involved? How much is the investment for setting up the grow room? How much are the monthly costs for water, electricity and other supplies? Can you grow in your house or do you need a commercial area? How will you be distributing your weed buds?

If you are considering growing marijuana as a business - treat it like a business. Do your research beforehand. Identify your target customer and how you're going to reach them. Research the balance of supply and demand in your market -- your work will be much easier in a market that is supply constrained, so that may influence where you decide to set up your grow. What are the financial and legal risks and how can you manage these risks? Are you willing to take a legal risk or not? A business plan can help you structure your thoughts as well as forecast your cashflow.

By the way: you do not have to have prior experience in growing weed to get started. What it will take is your genuine interest in taking good care of your plants and your ability to work hard, study hard and make changes on the way according to your learnings. It's not rocket science, but it needs dedication and passion. And you can do it, too.

Getting Started

When starting a cannabis business you will want to choose the right seeds first. Depending on the effects you want to achieve, you will choose different strains. This major choice (medical vs recreational) will largely determine the market you will be operating in.

After deciding on the results you are hoping for, you will then research the right plants for you and purchase seeds. With the seeds starts the lifecycle of your plants. From now on you will do everything you can to optimize water, airflow, nutrients and light.

We recommend using an indoor grow room and a hydroponics system (where your plants grow within water and not in soil).

These systems are scalable and - once you have the right control and measurement system in place - easier to manage on a daily basis. Less work for you, better environment for your plants. A classic win-win.

Because we know that starting an adventure like this can seem overwhelming in the beginning we have created this practical guide for you. Our goal is to walk you through all steps needed to start out and grow professional. We cover infrastructure as well as plant care. We help you to select the right strains as well as harvesting them at the right time. We share all our knowledge and secret tips from years of experience.

Growing weed includes various aspects of gardening as well as business. There is great opportunity in the market for medical usage right now. If you are acting smart 2018 could be your chance.

Our guide includes more than 30 pages of in-depth information on commercial growing. We added tons of tips from pros that will make you a pro. All steps of your plant’s lifecycle are described. We provide best case practices as well as secret growing hacks.

  • Not being perfect I have found that over watering is inevitably a problem no matter what the media. I’d like to offer my solution.

    Get a compressor with a cheap air wand. Shove the wand up into the bottom of the pot a couple of inches and spray air into the roots at low pressure, 5-10lb. max. A minute or two into each hole while delicately moving the tip around a few times to keep it clear and spread the air. Air in roots is better than drowning them while trying to correct fertilization issues. The middle hole, directly under the most dense part of the root ball, is the best. start.

    Its not perfect but it is better than not draining the flood in the bottom of your pots/buckets or whatever.
