Another new tool makes it possible to compare different seed strains. Enthusiasts can compare, for example, the strain WSS Amnesia Feminised with other feminised cannabis seeds. With this new functionality, Weed Seed Shop aims to make dialogue with customers even simpler. Weed Seed Shop is also stimulating site visitors to share their experiences with the help of product reviews and ratings for each sort of cannabis seeds.

Weed Seed Shop in style

During the development of the new cannabis seed webshop, the nine year old design was also taken into hand. The new house style is both clearer and more attractive, increasing its user-friendliness. The logo and font have been freshened up and the new colours serve a practical function, indicating the three different groups of seeds: feminised weed seeds, autoflowering strains and regular cannabis seeds.

How to Regenerate Cannabis Plants

Cannabis plants have the capacity to regenerate after harvesting, going back into vegetative mode and then flowering again for a second, and sometimes third, crop. Your cannabis plant has put a lot of energy and resources into creating an efficient root network and all of those nutrient pathways are still there after harvesting. Seems like a shame to waste them J.


So how do you do it?

Although it is possible to just cut your plant down and get regeneration from the stump, it is more efficient to follow the steps outlined here.

When you first harvest your plant, remove the top 1/3 from the main stem. Remove the buds carefully from the middle 1/3 of the plant, trying to leave as many leaves in place as possible. On the lowest 1/3 of the plant, remove the tip buds but leave some of the nuggets on each branch. It is from these flowering points that regenerative growth will occur, so the more you leave the faster the plant will regenerate.

Now feed the plant with a high nitrogen feed. It is important to point out here that you will have fed the plant some nitrogen throughout its flowering phase. If it gets starved of nitrogen during this period it will not have enough reserves to begin regeneration.

Switch the lights back up to 20/24 (or whatever your preferred veg cycle is). Look for new growth within a week or two, starting from the lower branches where you left the budding points. As soon as you have a good bit of vegetative growth going, simply switch back to flowering mode by changing the nutrient and light regime as normal. You can expect a second harvest in as little as 2 months, depending on strain and conditions.

You can also use this method to get a crop from a mother plant by simply reversing the normal process. Crop your plant as described above, and then use the second generation vegetative growth to provide clones instead of reflowering.

How to Pollinate Cannabis Plants

As people progress and gain experience with all the different aspects of cannabis cultivation, they invariably get to a point where they wish to cultivate their own seed. Despite all the great work by the big seedbanks that has resulted in the thousands of quality cannabis strains that are available today, seeds tend to be very expensive and this can be prohibitive when budgets are tight.

Producing your own seeds is a relatively simple task. Indeed, many growers have produced them by mistake, much to their dismay. It is essential that you take control of this process, producing either seeded plants, or sensimillia, as and when you wish.

First off, let’s have a short 101 on the cannabis life cycle so we all know we’re singing from the same sheet. Conventional cannabis cultivation has us remove all males as soon as they exhibit sexual traits. This means that the females remain unpollinated, essentially ‘virgins’, and put their energy into THC and resin production rather than seed production. The result is sensimillia, literally meaning “without seed”.  If a female plant does become pollinated she will produce abundant seeds. This does not mean that the plant is wasted, despite the fact that many growers trash accidently pollinated plants. Your seed bearing female is still useful to smoke, most of us have bought weed with seeds at some time. It’s just that sensimillia is better!

In the wild cannabis is essentially a wind pollinated species, although there may be a minor part played by some animals. Male plants will come into flower just before the females and will form flowers over a period of several days, ensuring that there is some overlap between the male and female flowering times so that they can be sure to be producing pollen at the correct time.

If you wish to collect pollen from your male plants it is important to keep a good eye on the sex of your plants. Pollinating all the plants in your grow room is not a problem but if you wish to control it and leave some of the females unpollinated, you will need to remove males as soon as you identify them. Put them in a separate room as far from the room with the females as possible. Unwanted pollination of female plants can occur with heart breaking regularity. That pollen has a great knack of getting to the females and you should ensure the utmost hygiene, changing clothes and washing hands when moving between rooms. Fans should always be turned off when dealing with pollen.

Having isolated your males you can begin collecting their pollen. Attach a paper bag over the end of a flowering branch on your chosen male plant. If collecting pollen for cross breeding you will have selected the male with the most desirable characteristics. A bag with a clear plastic window can be useful here, enabling you to see the pollen collecting.

Tape the bag around the stem so that it is completely sealed and then pinch a hole in the top corner to allow the branch to breath. Once a day pinch the breather hole shut and give the branch a good shake. You should be able to see the pollen begin to accumulate in the corner of the bag. Continue this process for a week or so.

Now cut the branch off below where the bag is attached. Tear open the top of the bag and remove the male flowers. At the bottom of the bag will be the pollen and some other bits and pieces of detritus. Pour the pollen into a ziplock bag, seal it and store it in the fridge.

Now it is time to pollinate our female. When the selected female is ready and her flowers have developed long pistils, invert the ziplock bag over the end of the cola. You will see the pollen attach itself to the flowers.

In some cases you may wish to pollinate individual female flowers. This is easily achieved by using a soft paint brush or cosmetics brush to gently apply the pollen directly to the flower.

And that is literally all there is to it. Once pollinated your female flowers will go straight into seed production and you will see the calyxes swelling with seeds. Do not be tempted by impatience. Seeds are not mature until they darken in colour. It is best to wait until the calyxes begin to open, seeds will pop out easily. Actual seed colours may vary from strain to strain but you are looking for dark brown or tiger striped. Light green or tan seeds are not ready.

Once you have harvested your seeds you should air dry them for a week or two. They may then be stored (a film canister is ideal) until required.

Watering cannabis plants

Clean waterAutoflowering plants just like regular cannabis (Sativa and Indica) plants need water to grow and produce healthy leaves and buds. Water is the lifeblood of the plant and cannabis plants are about 80 % water and this liquid is used in almost all of the plants life processes starting from photosynthesis and transpiration to nutrient uptake and keeping the leafs stiff. So if water is so important what are the optimum amounts of water and when , how you need to water your plants?

First of all there are so many variables like temperature, humidity, growing medium, strain, climate conditions, pot size and so on that there is not a one method – fit all solution but there are general guidelines that can help you to water your plants properly.

But first before all the watering techniques and explanations you need to know what water to use. Basically any tap water will be fine but you should let it sit for at least 24 hours within an open top container as all the chlorine in the water will evaporate and the water will also heat up to the temperature of the growing room and you won’t damage your roots with cold water full of the toxic chlorine. Chlorine will evaporate in the form of bubbles on the container walls , so when those bubbles have gone away then you should also check the PH of that water and if everything is OK then you are good to go.

One growing myth is that reverse osmosis water will be better for your cannabis, but this is not the case as in the reverse osmosis process the water is stript from ALL of the nutrients so every micronutrient will need to be supplied artificially. Many grow nutrients will not have all of the micronutrients in adequate doses as they will expect some of them to be in the water , so be careful with that purified water!


Underwatering happens when the plants gets too little water and its leafs start wilting. This process is common in nature but not so common in indoor grow operations as growers usually do exactly the opposite from under watering. Marijuana plants need a little dry period for the potency and for the optimum growth but it should not get so extreme that the leafs start wilting. The wilting process happens because the water pressure inside the leafs is not high enough and the cells start shrinking so the overall structure of the leaf  bends under its own weight. You can fix underwatering by simply introducing water to the growing medium and you will be able to see how the leafs start slowly strengthening and that means that they can start to fully photosynthesise again.

Underweatered Marijuana Plant


Over Watering marijuana plants is one of the most common inexperienced growers mistakes as usually they want to supply plenty of water but they don’t realize that too much water slows down the growth and excessive amount of water can introduce some mold or fungus that can severely damaging the plant. First signs of overwatering are that the leafs start to curl and bend strangely and the leaf tips start to turn yellow. This process is often misdiagnosed for nutrient deficiency but can be easily spotted if you know what to look for. Overwatering can’t be cured immediately but letting the plant use up all the water in the growing medium will be a start and slowly your weed plants will recover and keep on growing.

Optimum watering

If your automatic or regular plants get optimum water starting from the seedling all through the flowering phase then they will grow fast and will give you huge harvest. In different plants life cycles there are different techniques of watering and different amounts of water you need to supply.


In the seedling phase you need to supply your plants with plenty of water but not in share volume but in frequency. You need to keep your growing medium wet for the new seedling to grow and develop properly so you need to water your soil at least twice a day but with a minimum amount of water as too much water can kill the little sprout! My suggestion is to use a hand sprayer and spray the water around the newly developed plant but not directly on the stem as it is still fragile and can bend over. As for the amount I suggest to simply wet the surface as the rest of the pot will be wet from the pre soaking process before planting the seed in the ground. This moisture in the ground will be enough for the seedling to produce a good root ball so be careful with watering at this stage! Autoflowering seedlings are a little tougher than regular cannabis ones but there are no differences between autoflower and other cannabis plants in the watering process for this phase.


At the vegetative growth stage autoflowers will also need the same care as regular cannabis plants and that means that the watering process needs to be repeated every day if your pot is small or every other day if the pot is medium to large. Basically depending on the growing conditions every grower will need different time periods between waterings but a good rule is to check the first centimeters of the soil and if it is dry then it is time to water! There are also soil humidity meters but in general cannabis growers will water their plants depending on the surface moisture or holding the pot up / setting it on the site, to feel the weight of the soil, and with time every grower will be able to tell that the weight is too low so it is time to water your herb!


At the flowering phase you need to continue as in the vegetative growth phase because autoflwoers can grow under 24 hours of light and still flower! This skill gives them advantages but in the watering department it gives a bit more work as the flowers will chew up more water but the air temperature will also increase the water evaporation so you will need to water more frequently than you would regular weed plants. But again do the watering only when the soil is moist at the top or the pot is too light when picked up!

After knowing the right method for each phase you need to know exactly how to water your plants. In the seedling phase as I mentioned before you need to get a hand sprayer because large quantities of water can kill the little plant. But when the seedling phase is over you most definitely need large amounts of water to sustain optimum growth. This means that at each of the flowering and vegetative phases you need to pour as much water in the growing medium to get a 10% to 30% runoff water at the bottom as only then the growing medium will be completely wet and you won’t need to worry about dry soil pockets or dry spots full of nutrient that can give overdose to your marijuana plant.

If however the soil gets too dry between watering phases then you can get runoff exactly as you start watering because the soil can be pulled away from the pot sides and water will flow down by the sides directly through the pot. If this is the case then you have three options:

  • You can slowly wet the soil adding a little water in multiple watering cycles. You will need to do this process till the soil expands again. This process can be long as you will need multiple waterings in a short period of time so if you choose to do this be patient and don’t rush the process because you need the whole soil to get moist.

  • You can also crumple the top soil a bit in the gaps between the pot walls but be careful not to damage any roots. You can also add additional growing medium at those sides, but give exactly the same medium as the one you used for the initial potting.

  • The third and final chance is to mix a little bio-degradable soap inside the water as the soap will make the water “wetter” and it will more easily wet the growing medium and soak in the dried up parts so there won’t be as much runoff as without the soap.  If you choose this method know that only bio-degradable sop will be OK as other soaps contain hazardous chemicals. if you add soap to your water be sure to measure the PH of the water as some soaps can increase the PH level!

So now you know almost all there is about the watering process on cannabis plants but if I missed something or you have some additional question come to my blog and look around or ask for answers on any topic related to autoflowering or regular marijuana plants!
