Hello farmers, I found a good week by week article on bud development and figured I would post it for the new growers to check out....this was not written by me, its from the royal queen seeds website. I hope it helps some of the new guys n gals in their quest to become masters...enjoy!!
Part 1 - Intro
After weeks of mounting excitement the long-awaited moment the harvest is finally within arm's reach. The plants have grown incredibly quickly through their first three weeks of blossoming and have undergone a real transformation, after which began the slow formation of the buds. Ever- increasing numbers of white hairs appeared and formed the basis of the eventual buds, over which we have been drooling in anticipation.
After five weeks of blossoming there should now be hard, THCdripping buds found on your plants, that are still growing and expanding but which have now put the larger part of their development behind them. The blossoming plants should still be lovely and green, and the THC production firing on all cylinders. The leaves around the buds will become stickier and stickier and the many THC-rich resin glands produced on them will later be used for making a nice lump of hash with.
So at the harvest that is just around the corner we will have the leaves that we have trimmed from around the buds, and also the larger leaves that contain THC, both of which we will lay to one side to dry out well. We will then also have to decide whether we want to make water hash or skuff. There will be more about this in our harvest section.
Part 2 - Blooming boosters
In any case, as long as you have not given your plants an overdose of fertiliser then the very sight of your garden should by now be enough to get your mouth watering. It should look marvellous under the strong HPS illumination, which makes the numerous THC glands on your buds and leaves dance and glint in the light.
Because blossoming plants have additional demands for phosphorus and calcium, we give them pk 13-14 as an extra stimulation of the development of their blossoming. These substances are found in every basic nutrient mix, but in lower volumes, and with pk 13-14 we can make up the shortfall. The buds will be harder and more compact as a result If you are a newbie to growing, you are best to begin with the basic package of fertilisers, which consists of base fertiliser containing all NPKs (nitrogen, phosphorus and calcium-containing compounds), plus a pk 13-14 and a root stimulator.
With these basic products you will be more than able to grow yourself a great harvest. If you've got the bit between your teeth and it looks as if your harvest is going to turn out to be mostly problem-free, then you can apply a number of additional products such as a bloom stimulator and/or boosters and enzymes. It does not make any sense to add these relatively more expensive products immediately because they only help as long as everything has proceeded smoothly during the grow. Since you as a relative newcomer will undoubtedly have made a number of mistakes, then these products will in all likelihood be overkill and unlikely to have much added value.
Once you have worked through your main mistakes then these products do indeed offer something of value to your eventual harvest.
Enzymes take care of removing old root remains and reduce the salt accumulation in your medium that comes from giving them additional nutrients. Once you have been using the same bottle of nutrient for a while you will notice the top develops a white, crystalline deposit on it. These are the salts I'm referring to. By using organic nutrients such as plagron you can also reduce the accumulation of salts, since these contain considerably lower levels than the bio-mineral nutrients.
Part 4 - Climate
All the nutrients and water that you give your plants during their blooming period have to go somewhere. The water is evaporated from the leaves of your plants and then floats freely in your growing room. Since at the beginning of the blooming the plants still had little vegetation and were rather small, then little moisture was released into the air by the plants. Thanks to this, the air moisture was if anything too low rather than too high. Because our green plants grow more rapidly in a moister climate than in the dry heat produced by the HPS lamps, you can ensure a faster development and growth in the first week(s) by allowing the air moisture to rise.
The easiest way to achieve this without buying an air humidifier is to attach a dimmer switch to your ventilator. With a dimmer you can vary the speed of the air extraction. Connecting a dimmer is handy because with it you can better influence the climate. What's more, a ventilator without a dimmer always operates at full speed and this is not always needed, and not only wastes electricity but also creates more noise than is strictly necessary. It is not actually the ventilator itself that creates the noise but the stream of air that comes out of it.
So you are better off having a dimmer during the first weeks; it will allow the pump to not only operate more softly, it will suck away less moist air, thereby keeping the air moisture content higher and allowing your seedlings to develop more quickly. As soon as the plants become bigger you can afford to let the pump do a bit more work, as the plants are producing ever greater quantities of moisture, and you need to make sure that the humidity does not start to creep up too high once the formation of the buds is well and truly underway, around the fourth week of blossoming.
Too high a humidity can lead to the rock hard buds beginning to develop mould during their last few weeks of growth. When the humidity is too high there is a greater chance of damp getting inside the bud structure, which continues to grow around it, trapping the moisture. This trapped moisture can incubate moulds. Varieties of weed that develop especially hard buds have a greater chance of developing mould than buds with a more airy structure, thanks to the latter not trapping moisture in them so easily.
Once you have discovered mould in a bud then it is as good as lost, since the mould has been active inside before it became visible on the outside of the bud. When you have a lovely-developed bud and then a strange yellow coloured leaf sticks out the middle of it even though you have definitely been giving her enough nutrients - then you are best off pulling it softly out. If the leaf comes free easily, then the bud is infected. So make sure that you have a good ventilator in action during the last weeks. It is an investment when you are just starting out, but is a 'must' if you want to make sure that your harvest comes off without a hitch.
Not only does the ventilator ensure that the warm, damp air is removed, but it also makes sure that fresh, CO2-rich air is sucked into the space in which your plants are hard at work. They will need this fresh air to keep growing and blooming at an optimum rate. Try and make sure that during the last few weeks of blooming the air moisture is kept below 50%. Of course, you can grow in a cupboard without a ventilator by keeping the door ajar, but then will not get optimal results. If you are going to do something, you are better off making sure you do it well.
The dimmer in combination with the ventilator will enable you to master the environment better, and an outstanding climate increases your yield and the quality of your eventual harvest.
