Our marijuana seeds review database includes over 1000 strains. 20+ years of reviews by you guys of all the big names; Green House, Barney’s Farm, Paradise Seeds, Royal Queen, Positronics, Cali Connection, DNA Genetics , Bomb Seeds and all the rest!

Marijuana can be categorized into two main strains; cannabis sativa strains which are generally taller more. Or cannabis indica strains which are smaller and like its smell, offers a stronger more heavy stoned feeling.

There are 100% pure sativa strains (‘leggy’ plants and offer a more uplifting and euphoric high), 100% pure indica strains (compact, heavy stoned feeling good for stealth) and an endless variety of hybrid strains. Difference between Sativa vs. Indica. Find all seed strains here.

These days the big name seed banks make life easy and offer auto-flowering marijuana seeds which flower at a certain point in their growth, feminized seeds which are 95% to 99% female and regular seeds. Of course you can also buy autoflowering feminized seeds to make life super automated.

Take a look at our research and reviews of the Top 10 Best seed strains in each sector.

    – Big Bud to Pineapple Kush – we love Indica. – Powerful cerebral high, from Amnesia Haze to Trainwreck. – Auto seeds will flower automatically. – The Best Cannabis Cup + others all in one place. – These seeds are chemically treated and 95% – 99% are female. – Best strains for solid CBD and known to be used for therapeutic purposes. – Amazing chance to get 25%+ THC. a nice sativa and India mix, well rounded and highly bred strains. – Northern Lights, Jack Herer, Afghan, we put them all to the test. – Low, quick growing, fat juicy seed strains from Lowryder to Mosca.

Hydroponic Systems

Hydroponics Systems master page to choose between Aeroponics, Deep Water Culture (DWC), Drip, Ebb and Flow, NFT, Sea of Green, SCROG or Wick.

Hydroponics simply means that the plants can grow without soil. They will usually grow in an inert growing medium and all of their micro and macro nutrient requirements will come straight from the water flow.

The advice from companies like Dealzer and SuperCloset are second to none – you can have the kit the next day and get growing by the weekend. We have worked all the major supplies over the years and these are the only two companies we recommend, I can honestly say you need to watch your back when dealing with some of the others.

Or you can save some dollars and piece it together from Amazon or eBay and get a decent system together – it will work and it might be just fine for what you need. Your a word of warning though, we find many of our visitors end up wasting time and money because pieces don’t fit, you buy more than you need, quality is sometimes questionable and advice is zero.

There’s an amazing variety of hydroponic systems available with pros and cons to each. Choose yours.

Aeroponics

The process of growing marijuana in a fine mist rather than an actual nutrient solution. The roots are confined to a dark, moisture proof area to keep humidity high with intermittent spraying using micro mist nozzles.

Continuous flow / Top feed system

Using a 2 to 4 inch PVC tube with holes cut in for plants there is a continuous flow of nutrients pumped over the root system. NFT is considered easier.

Deep Water Culture

(DWC) + Recirculating direct water culture systems (also known as RDWC) + BubblePonics

Drip Irrigation

This is a terrific water/nutrient saving system. Nutrients are dripped right next to the root system which is held in aggregate (medium). There is less evaporation and this system is good for stealth or apartment growing.

Ebb and Flow

With pots situated in a tray above a reservoir, the nutrient solution ‘flows’ into the tray and then is allowed to ‘ebb’ away.

Nutrient Film Technique (NFT)

Similar to the Ebb and Flow, however the tray above the reservoir is tilted so that a thin film of nutrient flows from the top to drain at the bottom. Nutrient solution is either timed or continuously pumped past the root systems.

Wick system

A very basic system, with either plants all sitting in a medium or within pots situated above the main reservoir and wicks of thick cotton connecting the two. The wick uses capillary action to absorb nutrients up into the medium.

Sea of Green (SoG)

A Dutch method to grow marijuana, not so much of a hydroponic system just a method of maximizing crops. The concept is to force the plants to flower when they are very young and small, to push out a sea of green of marijuana plant heads. Got to love the Dutch!

Screen of Green (Screen of Green)

Similar to the Sea of Green system except that a screen of chicken wire is placed over the heads of the marijuana to help control and top them.

How to Grow Marijuana Indoors

The decision to grow weed indoors instead of outdoors is one that will take you on a journey.

Some of us like a basic hydroponic system with a little tinkering while others want the best, most automated and perfect grow box or grow tent kits and have the time to make that happen. Either-way growing marijuana indoors can be a very rewarding experience, you choose the seed strain, choose from Top 10 THC, Top 10 CBD, Top 10 Feminized or Top 10 Autos you control the environment, the temperature, ventilation and C02, what nutrients you use, the pH, what grow lights to use whether it is HID (HPS and MH), CFL or LED grow lights, what light cycle, when to flower and when to finally harvest your little babies. There are so many different factors that need to be considered, but don’t worry, that’s what we are here to help you with.

How to Grow Marijuana Outdoors

Basic requirements for marijuana = water with the right pH level, grow lights, nutrients and suitable air. However when you choose to grow marijuana outside you should bear these basic requirements in mind and ask yourself at each stage how can I improve what I offer my plants naturally.

Cannabis life cycle outside – Cannabis is an annual plant and if grown outside it germinates in the spring, lays down a lot of vegetative growth throughout the summer, and then flowers in the fall. When growing outside it is best to start germinating seeds inside and then planting the seedling at the start of the season in spring. So germinating your marijuana seeds early!

We review the Best Outdoor seeds

We review the Best Organic Seeds

The season will vary depending on how far you are from the equator and also the elevation of your proposed marijuana garden. Generally you should be able to plant seedlings after the last frost of spring and grow right through to the first hard frost of fall / autumn, specifically the average overnight temperatures should not be below freezing 32° F or 0° C at any point because that kills marijuana plants.

The main issue growing outdoors is site selection, security, access to sun throughout the grow (watch out for late in the season and nearby trees) and access to water. If you are guerilla growing then there will be crucial outdoor visits, sexing marijuana plants and of course the final and delicious harvesting time.

Marijuana Grow Lights

Do you know the difference between LED lights, HID lights, HPS lights, Compact Fluorescent Lights (CFL) or full spectrum lighting or how many plants you can grow under a given light?

Start here with our Marijuana Lighting Guide.

What is the difference between, IR red and blue spectrum, nanometers, true Watts, HID/CFL/HPS/MH/LED, light cycles and timings? This knowledge base will help you get to grips with the ins and outs of each, as well as providing ideal sources to get your equipment.

Whether you need to set up a small and discrete growing environment or a larger grow space like a grow box or huge grow tent, we can recommend the best lighting for your needs and then point you in the right direction where to get them.

LED Grow Lights

LED grow lights have been growing marijuana for over a decade now and even NASA used them in 2012. LEDs have been in production since 1968 and as the decades progressed LEDs got brighter and cheaper to make. You now see super bright LEDs in car headlamps, stadium lighting and of course LED grow lights.

The technology is here in a big way and it works, fantastically. We know one of the best know Dutch seed banks uses them to grow some of their top secret buds, we have seen it with our own eyes and know they work better than HPS. However, not all LEDs are created equal. The cheap ‘purple’ light looking plastic UFO junk are the ones to steer clear of, look for ‘white light’ full spectrum, just like the sun, models with no fans, solid construction, honest specifications and a high end warranty. The full spectrum models in the top end range run nearly cold to touch, save around 50% in electricity and will run for over 12 years growing crops without a single bulb replacement. We take LED grow lights very seriously and review all the best models here every year.

High Pressure Sodium (HPS) Grow lights

High pressure sodium marijuana grow lights are a good choice for a lot of people, they have been used for growing marijuana indoors for decades. However they are not brilliant at transferring electricity into light and waste a lot of electricity on producing heat instead. LED grow lights are far more efficient at that process. The light HPS emit is also strong in the orange / red spectrum, around 2,200k, due to their inherent sodium content. If a gardener were to start a young plant under a HPS bulb, she/he would see impressive vertical growth so it is why MH lights with their more blue light are often used in the first stages and HPS in the later flowering stages. .

Metal Halide (MH Grow Lights) – A type of HID

MH grow lights – Metal halide marijuana grow lights primarily emit light in the blue spectrum which promotes excellent photosynthesis and therefore green vegetative growth. Blue light also keeps plants more compact, it is the closest thing to real sunlight. If you are going to use just one light this is a good compromise.

LED grow lights vs CFL

The compact fluorescent lights (CFL) are a fantastic way to grow in small stealth locations where heat emissions are very important to control, they are cheap to buy and run but they are generally limited on power and that means a poor yield. If you want some more power but still want to maintain a small heat signature, albeit more than CFL you might want to start looking into LEDs – especially the full spectrum LEDs. We have a good article here that outlines what you might expect from LEDs there days. More on LED grow lights.

How to Grow Cannabis From Seed In 10 Easy Steps

Whether it’s to control budget or because it’s hard to acquire clones, many are interested in learning how to grow cannabis from seed. Growing marijuana has never been easier or more accessible. Our guide to growing cannabis takes you from the planning stages to the final stages of your harvest. If you’re ready to start growing your favorite strain, keep reading.

Step 1: Sourcing and Germinating Seeds

If you can’t or don’t want to grow from clones, seeds are a great (and some may say better) alternative. Finding high-quality seeds is easier said than done. Dispensaries in states with medical or adult-use cannabis may carry cannabis seeds. In states without cannabis laws, finding seeds is strictly limited to online cannabis seed banks.

Do your research on the many available seed banks that ship to the U.S. While many say they ship worldwide, they may exclude the U.S. in the fine print. Seed banks differ in seed selection. They also offer a variety of payment methods and discreet shipping. Some of the most popular seed bank sites include Attitude Seed Bank, True North Seed Bank, Amsterdam Marijuana Seeds, and Seedsman.

Cannabis seeds require germination to jumpstart the growing process. The simplest way to achieve this is through the paper towel method. During this process, the germ in the seed breaks through the outer shell forming a root, also known as a taproot. Germination can take a day or up to a week. Germinated seeds can be placed in the growing medium.

Step 2: Location and Light

Cannabis can be grown indoors or out. However, most towns that allow for home cultivation require gardens to be secured and away from public view. Regardless of where you choose to grow, your space must have the right amount of light and space to grow.

If you’re growing outdoors, consider any large trees that may cast a shadow or shrubs and bushes that can limit its space. North American growers should plant their garden in a space that faces the South to increase the amount of light it gets.

Growing indoors? Consider the height of your space and garden. Don’t forget about including the hanging lamp height in your calculations. Grow lights need to be a certain distance away from lights to prevent burns and avoid stretching if the light is too weak.

Indoor growers can grow in basements, garages, rooms, and even closets. Many growers start off with a grow tent, which provides a contained space for cannabis gardens. Many tent options come with all the necessary pots, lighting, filters, and fans needed to start growing from seed.

Once you’ve chosen your preferred space to grow your garden, it’s time to consider lighting, an integral part of the process. Most growers choose metal halide (MH) lamps during the vegetative stage. They switch over to high-pressure sodium (HPS) bulbs during the flowering stage.

Others may stick to their fluorescent and LED options. These can provide the right level of supplementary lighting for HID lamps. If you’ll be depending on LED lamps for your garden, make sure they have a full spectrum of white light. Full-spectrum LEDs are a bit more expensive than conventional HID lights, but they can save you money on energy bills. 250 to 400-watt HID lights can work for small gardens.

Step 3: Medium and Container

The medium of your plant refers to the base structure of your plant’s roots. A container keeps your medium, nutrients, and water contained when needed. Outdoor growers can use dirt, topsoil, compost, and other soil amendments to create a thriving microbiome needed to feed the plant’s roots.

Indoors growers, on the other hand, are increasingly preferring soil-less growing methods. Mediums made from peat, sphagnum, and coco act like soil. They hold the moisture and air needed to absorb the necessary nutrients.

Many smart pot options have holes around the sides and bottom of the container to improve water drainage. These breathable pots allow roots to get oxygen during the dark cycle. The pots prevent water build-up, which can lead to root rot and mold.

Step 4: Nutrients

Choosing the right nutrients is important for the best growth possible. Cannabis plants require certain nutrients to grow its roots, foliage, and buds. Nutrient solutions usually include an N-P-K ratio (nitrogen, phosphorus, and potassium). Nutrient solutions come in grow and bloom formulas for vegetative and flowering stages, respectively. Grow formulas have higher ratios of nitrogen compared to bloom formulas due to their differing needs.

Start off by reading your nutrient solution’s instructions and create a diluted solution at ½ to …” the recommended dosage. Starting off with a lower-than-recommended dose ensures you don’t overfeed and ruin your crop. If within a week or 10 days you don’t see any signs of nutritional deficiencies, you can increase the dosage to the listed levels on the packaging. If however, your plant looks healthy, you can continue your feeding levels.

Ideally, you want to use organic fertilizers to avoid salt build-ups in the medium. Organic and veganic nutrients are pricier than synthetic fertilizers, but they produce a far better product. Organic nutrients are helpful to bring out the cannabinoid and terpenes from your strain.

Some outdoor growers choose to feed their gardens through a composted medium that has many of the minerals needed for the plant’s growth. Others use time-release pellets that contain nutrients that are slowly released into the medium.

Step 5: Vegetative Stage

A plant’s vegetative stage is the first (some might say most important) part of the growth process. Much of the plant’s size and yield are produced during this time. Some may say that longer vegetative periods can lead to bigger yields. Vegetative periods can last between a couple of weeks to a couple of months.

Plants will remain in a vegetative stage when the light-dark cycle has more light than dark hours. Indoor growers set light timers to provide their plants with a minimum of 18 hours of light per day during this stage. During its dark cycle, the roots develop, so every hour of light and darkness matters.

Many growers use MH bulbs during this stage. MH bulbs have blue wavelengths, which are necessary to keep your plants from growing tall and wild. Indoor growers may prefer this set-up to keep their plants short and bushy. MH bulbs can produce plants with short internodal lengths (the distance between the main stem and the branches).

During this stage, you can employ different training and pruning techniques to maximize growth and yields. For instance, topping a plant involves removing the top shoot of the main stalk near the end of the vegetative stage. When cut, the plant produces additional shoots under the shoot’s cut, where buds can form during the flowering stage.
