The current approach to cannabis is not working, and the Government of Canada seem to be committed to taking a structured and long term approach at getting this right.

The federal framework is intended to be in place once legal cannabis for non-medical purposes becomes accessible for retail sale, no later than July 2018.

Any Canadians here on the ground verify this, or is the news out there just paying lip service to the Canadian Government?

How do you feel about clothing with cannabis leaf motifs on them?

Are they just cliched now, like all the Che Guevara t shirts you see.?

Or do you think the symbol means much more than a nice motif to stick on a sweatshirt?

Normal news bugs me out.

But not Marijuana news, which is, generally, always good news 🙂

It sounds like the state of Illinois might be on their way. When you read that

"Cook County Board President Toni Preckwinkle signaled her support Tuesday for an advisory referendum on whether recreational marijuana use should be made legal.

Preckwinkle, a longtime advocate for reducing the focus on the decadeslong war on drugs to concentrate more on violent crime, backs legalizing recreational marijuana in general as well as putting a referendum on the 2018 ballot"

and that...

"Based on sales of pot in Colorado, the Marijuana Policy Project, a national advocacy group, estimates sales in Illinois could generate between $350 million and $700 million in government revenue a year."

Generally when prominent politicians start to make the right noises and then when the once dragging their heels realise there maybe tax dollars to harvest, the wheels start to turn a little faster.

Any natives of the stat if Illinois in here want weigh in? Is she really for this or riding a popularity wave?

Marijuana Seeds

Our marijuana seeds review database is huge and includes brands such as Green House, Barneys, Paradise Seeds, Royal Queen, Positronics, Cali Connection, DNA Genetics and the rest!

 

Marijuana can be categorized into two main strains; cannabis sativa strains which are taller more ‘leggy plants and generally offer a more uplifting and euphoric high. Or cannabis indica strains which tend to be smaller more compact (good for stealth) and like it’s smell, offers a stronger more heavy stoned feeling. There are 100% pure sativa strains, 100% pure indica strains and an endless variety of hybrid strains, find them all seed strains here. Read more about the difference between Sativa vs. Indica.

These days the big name seed banks make life easy and offer autoflowering marijuana seeds which flower at a certain point in their growth, feminized seeds which are 95% to 99% female and regular seeds. Zamnesia has a huge range of seeds and smoking products.

Of course you can also buy autoflowering feminized seeds to make life super automated. Learn more about genetics and the different seed types such as ‘white’, ‘blue’ and haze.

Hydroponic Systems

First visit our Hydroponics Systems Master Page to get a run down on all the different hydro systems available to you.

Hydroponics simply means that the plants can grow without soil. They will usually grow in an inert medium and all of their nutrient requirements will come straight from the water they are added to. After choosing your hydro setup you will need to pick what growing medium to grow your marijuana in; some prefer the organic nature of good soil and others like the more synthetic such as rock wool and perlite. Apart from this difference the way you set up your grow room will be the same.

We always suggest buying a Grow Box, Grow Tent or Stealth hydroponic kit from experts.

 

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. Here we direct you to the reviews.

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.

Growing Marijuana Indoors

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

The journey for some is to achieve the biggest yields, others like to grow with organic nutrients, or achieve a perfect Sea of Green or SCROG garden. The key is to get your grow room planning right.

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 differnt

Hydroponic growing systems can be simple affairs such as Wick or NFT or more complex indoor growing concepts like Sea of Green or Screen of Green or large grow systems.

Growing Marijuana Outdoors

Basic requirements – Marijuana plants need water with the right pH levelgrow lightsnutrients and suitable airventilation and temperature. However 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?

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!

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.

 

If you have had a successful vegetative phase then flowering will begin automatically as the days get shorter. Approximately 10 – 12 days after the flowering stage begins you will start to notice two small pistils right at the crux of the branch joint, take a note of the sexing marijuana plant pics. To produce the most potent buds it is necessary to remove the male plants as they have very low amounts of THC, CBN and CBD when compared to the females and they will also make the female plants start to seed. Remove the male plants before they pollinate the female plants as once pollinated the females will turn to seed and we don’t want that! The flowers are the bud, the thing we’re looking for and what you will harvest and smoke.

Without males around the female plant will put all of her energy into creating sticky, THC-laden flowers rather than cannabis seeds. The result is essentially a virgin plant, or sensimillia, which comes from the Spanish ‘sin semilla’ or ‘without seeds’.

  • Marijuana Grow Lights

    If you don’t 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. What is the difference between, red and blue spectrum, nanometers, 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. Start here with our Marijuana Lighting Guide.

    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.
