A How To Guide to Guerilla Growing

As the temperatures warm up and finally it looks like spring may be round the corner for many of us, we begin to think about outdoor growing, and even doing it guerilla style.

What is guerilla growing?guerilla_garden

Quite simply, its a hidden, secret outdoor grow, normally not in your own garden, but amongst the wild places.

Advantages of guerilla growing:
  • well, unless you are unlucky to be caught at the spot and been under surveillance, the chances are that you can’t be caught to rights on these plants.
  • you don’t need to dig up your nan’s best rose bushes or even have your own garden to get the benefits of an outdoor grow

 

Disadvantages of guerilla growing:
  • you can’t be with your plants every step of the way. For some of us, used to spending time literally watching them grow, that’s a hard break to make.
  • losses – whether to animals or people, you have to accept no place is safe enough.

Picking your plants: photoperiod or autoflower?

As indoor cannabis growers, we’re used to playing God and creating our own perfect microclimates for our marijuana to flourish in. Growing outdoors however means we have to leave it up to “the big fella” and quite frankly he doesn’t do as good a job for many of us. So when picking your strains for outdoor grows take into consideration factors like length of decent summertime, the amount of rain you generally get and so on. Sensi Seed’s World Climate Map is very good at enabling you to quickly pick your area and gives suggestions for what will grow well there.   But having been at the receiving end of one too many October thefts of a virtually finished (albeit unflushed) bud heavy plant, I’m going to come out and say it:

Autoflowering Cannabis is great for guerilla grows

There are many reasons why autoflowering cannabis is ideal for growers who want to use the guerilla approach for their personal yearly nug supply:

1. Photoperiod plants grow BIG. Whilst this means that someone with an ideal climate like mine can get 1k plants, it has its disadvantages:

  • big plants are thirsty plants.
  • big plants are noticeable plants.
  • depending on where you are in the world, you have to pick your strain according to the length of summer time.
  • everyone, from thieves to the police, is looking for outdoors grows at the beginning of autumn. In Spain special helicopters do the rounds in October looking for green foliage standing out against the arid terrain. I’m pretty sure this goes for elsewhere too ..
  • March-October is a very long time to wait.

2. Autoflowers on the other hand:

  • smaller plants need less water
  • smaller plants hide in natural foliage easily
  • autoflowers finish according to age rather than hours of darkness, meaning you can start cropping 10 weeks from germination date.
  • you can mix and match your autos, from the fast auto in 8 weeks yielding 20g of dried bud to the super autos which may take 4 months but will give you 300g ..
  • Mix and match not only applies to finishing times, but to smoke appeal too. Lots of different types mean lots of different smoke …

When autoflowers first started being developed, they were hailed as the guerilla grower’s godsend. Only they weren’t. People got fed up with lollipop buds, plants that reverted to standard photoplants, and smoke that wasn’t really all that. However some great work by breeders such as Dutch Passion, Dinafem and Short Stuff have raised the bar, and now there really are some great yielding stable autoflowering genetics with THC contents matching standard plants.

And as for the lollipop buds? Read our Top 10 Tips 4 Autos & Why the Veg Stage is so important to an Auto Grow to get the most out of these little beauties.

When to plant an outdoor grow

OK as we know people come from all over the world to this site so to give you an exact date isnt practical because its going to vary to your individual climates …

But here is the general idea:

If you are looking for a early season crop, then the most important factor as many of you vegetable gardeners know is that we are waiting for the last chance of frost  to have gone ..

However the temps of the grow during the cycle are going to affect the yield and possibly the quality of the harvest

For northern US and northern Europe, many plant autoflower seeds once a month from May until September. The earlier crops will probably be smaller than the crop planted in the beginning of July. But done properly there is no reason to assume the quality will be affected with those dates

In the Mediterranean we can pretty much plant from March and I have been harvesting some years until Xmas day (although saying this, we had a foot of snow fall in the mountains on March the 12th this year so nothing is set in stone).

  • For the plant to grow well it will need 8 hours of direct sunshine and ideally your night time temperatures will not drop below 10c (50F) but the plant will tolerate a drop to 6C (42F). Its not a positive thing as there will be some element of shock that could interfere with the quality and quantity.

 

guerilla grow cannabis

Choosing your spot(s) for a guerilla grow.

They say that preparation is the key (and we’ll get to more of this later), but with a guerilla grow planning is important too.

Choosing where to plant your stealth cannabis plants deserves a deal of fore-thought long before you even start germinating your marijuana seedlings. Putting a little work into where you decide to plant is going to be the deciding factor in whether you reap the rewards of all your work or just end up growing plants for others.

Avoid public areas or well frequented footpaths. Now don’t get me wrong, there is nothing more funny or satisfying than chucking some auto seeds in a  police station’s planting area or in front of the local town hall, but lets get real here: you’re unlikely to see the plants grow to maturity. (Still funny tho – I had a friend in Spain that went around every bar planting seeds in the flower pots. Everywhere you went there they were, but I don’t believe he ever managed to see one through to the end)

Think about your chosen spot from all viewpoints (including above), and bear in mind whether a deserted area in

the tail end of winter will still be empty come the summer picnic season.

For me when selecting a planting area there are some things which are a must:

consider your spot from all viewpoints. from the helicopter, this secret patch just stood out like a sore thumb ..

Biggest for me is access to water.

One guerilla grow I did had 27 x 6 foot photoperiod plants scattered in block around the mountains of where I lived. Southern Spain is a semi-arid area (in fact its Europe’s only desert), with temperatures reaching 40C (104F), the plants started   drinking 2/3 gals a day. Getting water to my beautiful but struggling plants became a nightmare, as I spent 3 hours a day rock climbing with 30 kilos of water, making trails through the undergrowth and completely negating the “plant em and leave them” approach necessary for secrecy.

Quality of soil

Another point to consider is the quality of the soil and the surrounding planting for camoflauge. Here’s a tip:

Brambles and stinging nettles are full of nitrogen, and enrich the soil. If you find a hidden spot with plenty of these, then you’ve found a guerilla goldmine:

  • the nettles themselves are evidence of good soil
  • they like a damp soil, so show that there is plenty of moisture in the area
  • they give shade to young / short plants
  • they act as a deterrent ..  lets face it not many people thrash around in patches of brambles (apart from you that is)

So in summary: you are looking for a place which isn’t on a hiking trail, yet still is accessible enough for you to get to. It shouldn’t be overlooked, and your cannabis plants shouldn’t stand out as green against a bare background. Soil should be good, and if possible there should be cover plants both for disguise and protection. You also need a fresh water source or be prepared to lug bottles of water.

 

Good places to start:

The side of railway tracks – just don’t get caught trespassing & remember safety signs are there for a reason. It can be  a double edged sword: ok you are less likely for the general public to come across your girls but to be honest you are more likely to get caught by the authorities tresspassing

Another good area is arable land (in the hedgerows) but make sure the farmer doesn’t follow a herbicide spraying programe because that will kill your girls like nothing else would.

You need to think carefully about when you are likely to plant and its well worth putting the energy into it.

And then you need to do it all again. You ever hear of the saying “don’t put your eggs in one basket” here this applies as well. If you’re looking for a good yield from autos for your efforts it really is a numbers game.

  • You should plant your crops in different areas in (loose) blocks of whatever numbers you want. I aways think of my glass as half full so I might plant in blocks of ten autos in ten different areas. And if in the worse case senario I only get away with 10% reaching maturity I have covered the cost of the seed and will have enough weed to last me a few months at least compared to having to go out and buy it works out much better for me at least

And for every block not discovered above that then I’m a happy grower indeed….Bonus!

Why such a low harvest rate?

This applies to photoperiod plants as well as to autos, but you have to assume that some, if not many, of your little wild plants won’t make it through. Its not just thieves and responsible citizens, though. You’ll lose some to diseases, and others to wildlife.

Now I came across this device on Amazon which looks like it may work wonders in protecting your precious plants if your main problem is the small and furry kind .. Now I haven’t tried it myself, but it has AMAZING reviews by zillions of satisfied customers  … keeps away deer, cats, dogs, rabbits (and in my neck of the woods the problem critter would be goats).

To help aid not having areas discovered by people, its good to learn some basic field craft:

  • take different routes to your planting area .Its suprising how quickly a twice a  week visit to your site can end up leaving a obvious trail for others to follow.
  • Visit the area at varying times
  • Park your vehicle in different places

 

Basically just don’t get lazy. Think like a fox! And use some common sense …

Preparation and Planting.

Now this is a fact if you dig over the earth and add plenty of organic matter,  then you are going to get bigger healthier more productive autoflowering cannabis. Its great if you have a head start by fertile soil (remember the brambles and nettles?)

I would advise a collapsible trenching spade such as the military use: 

If possible dig over the area well and add as much well rotted manure as you can carry there. I always add a spoon of epsom salts and any other slow release fertiliser you can think of which will help improve the condition of the soil and add the needed nutrients for a great start. I can’t emphasize enough how important it is to dig over a much larger / deeper hole than you may think necessary. Cannabis produces a great root system in order to grow so quickly, and you can help this by loosening the surrounding soil area.

  • In a guerilla set up I don’t worry about ph issues  but go by whats growing naturally in the area to give me an idea that my plants will flourish in that soil.

 

To give the plants the best start in life, I find it best to grow my seedlings for the first two weeks indoors. This means I can germinate them with a high success rate and nurse them through the delicate first 2 weeks. This also means I can get a jump start on spring and get young established plants out into the ground when soil temps are only just thawing enough to germinate cannabis seeds. Planting the sprouted seeds in 3″ pots means they are fairly easy to carry in a sports bag, with only a few casualties.

When I plant, I have prepared the ground in advance so it’s a simple matter to pop them in the ground, quickly firm the soil and water them in. The least amount of time on site with cannabis plants in hand, the better.

  • Normally when I plant I will also liberally sprinkle slug pellets (not the blue ones) and also a top dressing of ferrit shit. The former protects against slugs and snails, the latter against rabbits.

(If you’ve no access to a ferrit then there are commercial brands available to deter four legged pests)

  • When  the plants are young you need to keep an eye on the weather, as if its too hot, it can only take a short time of sunshine to shrivel a young and tender plant - I would normal check them around every 3 days in hot weather
  • If I’m using unfemmed Ice Express I will go back a week after planting the two week old seedlings and remove the males.
 I like to use un femmed seeds that are of a excellent quality straight from the breeder as they work out by far much cheaper even after allowing for the:male female ratio.  For fifty seeds at  70 dollars I can have 3 separate areas with around eight to ten female autos per planting area.

What I like about autos is that with some strains I can have them sexed by the time they are 21 days on average so there is a argument to wait until sexing before planting out. However fems do make the whole guerilla growing a lot easier in that respect – but its a bigger burden on the pocket

OK so they are in the ground and if you’ve followed the above advice there is very little else to do apart from watering and perhaps feeding later in flower. All the work in guerilla growing was spent in the planning and preparation.

Choosing the right autoflowers for your guerilla grow.

This is going to depend on where you live and the time of year. If you live in a relatively cold country then you will want to use a strain with a little bit of purple & blue genetics in it for the first and last yield of the year, as these types of strains are more able to handle colder wetter conditions. I’d also go for the quicker varieties, 70 days and under as these will be exposed to the vagueries of weather conditions for shorter time periods.

Recommended Autoflowers for warmer climates:

 

If you browse the Seed section of the site, you’ll find plenty of fast autos for quick crops, as well as some great super autos that will give you yields as well. I highly recommend looking through the bulk buy section for anyone seriously interested in taking up guerilla growing on any scale this year. I don’t think you’ll find better deals anywhere on the net. I’ve found that bulk buying autoflowering seeds loose halves the cost of the cannabis seeds and means I can afford to lose a few. All the seeds listed in our Seed Shop are sold through Original Sensible Seeds, who process payments and orders, but what you’ll also find are genuine growers reports on the varities and why Growers Guide to Cannabis recommends them.

Don’t get surprised when you lose some ……that the name of the game and that’s why you planted so many and that the challenge a true guerrilla grower will be prepared to deal with.

Good luck!  …. & don’t forget to chuck a seed in front of the local police station ….

Free the weed

And happy tokin

  • You say it’s good to get a patch where there are plenty nettles/brambles. Are there any circumstances where you’d want to clear an area before planting? And how close would you plant your seeds to the nettles/brambles?

    • Hey Arran
      ok mate the reason I say choice a patch of nettles or brambles is because this is an indication of an extremely good water retentive fertile soil and for larger photo period plants can be an excellent camouflage as the individual heads will poke out of the mess without having the immediate form of a plant
      however saying this indeed it is a point because of the smaller nature of the autoflower that a good hard prune of the nettles may be beneficial to allow more light for smaller plants

  • Hi would there be a problem with the roots of nettles infringing on the plants roots should I weed and dig out around the plant after I have planted

    • weed widow says:

      cannabis roots should be able to “stand their own” however whilst nettles are a good sign of both 1) good earth and 2) a deterrent, you dont really want any competition for this good soil.
