It is possible that it was too dry before you put it into the jars. Weed that dried to fast or is too dry will be harsh because the by-products of photosythesis never got to break down fully. If they are too dry in the jars the during process doesn't get going.

The way I tell my buds are ready to go from hanging to the paper bags is by how they feel. When the tips of the buds feel crisp to the touch I remove them from the stems and put them into the brown paper bags. This step allows the moisture from inside the buds to escape and be evenly distributed through the bud and any excess moisture will be absorbed by the paper bag. After that step I go to jars.
You can most certainly add moisture to those buds and get the curing process going again. Now if the buds were like a year old, no but they are still fresh! Do you have fresh, moist leaves from your plants? If so you can add a few of the fresh leaves to the jars, the moisture from them will condense inside the jar and the buds can absorb it. If you don't have fresh leaves there are a few things you can put in the jar. Some people add slices of orange, lemon, or lime peel; adding those to your jar will also add the scent to your buds. Some people don't like to use those because they don't want the added fruit scent; in these cases Ive heard of people cutting a small piece of terrycloth, dampening it and then adding that to their jars. I have also heard of people taking the buds and putting them in paper bags with a small container of water then closing the bag; basically a homemade humidor. You could also invest in a humidor, most cigar shops will have them for sale.
You read this where? Everytime I smoke whether it's 10 minutes after cutting a bud or 3 weeks I still get blazed....

Whoaa, I never said you wouldn't get high from uncured buds, I just said curing increases potency, it basically allows them to be at the peak potency because of the chemical reactions that occur. I certainly didn't just make it up, I read it in a number of places. Plus, I have doing this long enough to know there is a noticeable difference in quality between cured and fresh buds. You can find the information in several books, guides, and articles about cultivation by some of the most well known and respected marijuana cultivators, breeders and activists; people like DJ Short (I'm sure you like his Blueberry strain), Jorge Cervantes (If you read about cultivating chances are the info came from one of his books), and Ed Rosenthal.

I'll also provide a few links for you to check out, one is to an article by DJ Short.
Here's the explaination:
Moisture is essential for the curing process, it is both your friend and enemy. If too much moisture is left in the buds, with out the regular mixing, venting and turning of buds involved with curing, molds and bacteria can quickly form and ruin the taste and potency of your stash. On the other hand, without the necessary moisture metabolic processes essential to curing do not take place.
Fresh cannabis plants are around 80% water (all %’s by weight); curing generally begins after the cannabis has lost half of it’s initial mass, and contains approximately 33% of it’s initial water.
Once curing is complete and the pot is “dry”, it should still contain 10-15% moisture, approximately 2-4% of its’ initial water. This is an ideal because most bacteria and molds can not grow below 15% water content, and below 10% cannabis buds tend to powder.
Naturally, as the metabolic processes continue during curing, the conversion of cannabergerol to tetrahydrocannabinol will continue and the potency of the pot will increase. This is because cannabergerol (CBG) is the non-psychoactive precursor for tetrahydrocannabinol (THC). Of course, the exact change in THC content will necessarily be dependant upon the concentration of CBG in the fresh material at harvest. Of course any remaining precursors necessary to form additional cannabidiol (CBD) and other cannabinoids will also be consumed and converted.
Curing proceeds while the leaf is still alive, for until it dries, many of the leaf's life processes continue. Since the leaf's ability to produce sugars is thwarted, it breaks down stored starch to simple sugars, which are used for food. This gives the grass a sweet or earthy aroma and taste. At the same time, many of the complex proteins and pigments, such as chlorophyll, are broken down in enzymatic processes. This changes the colour of the leaf from green to various shades of yellow, brown, tan, or red, depending primarily on the variety, but also on growing environment and cure technique. The destruction of chlorophyll eliminates the minty taste that is commonly associated with green homegrown.
Potency during curing and storage can be maintained by observing some basic precautions. Excessively hot temperatures will promote oxidation and the growth of mold and bacteria, and very cold temperatures can prolong curing and drying for up to several months.
1. The buds need to be kept in the dark, protected from light, which will quickly decompose the THC.
2. Moderated temperatures should be observed during curing, 50-75F being ideal.
Also as these metabolic process take place, the plant needs energy which leads it to consume the sugars, starches, nitrates, and minerals. Many of these compounds are metabolized and released as water and carbon dioxide, therefore removing what is essentially inert material from the pot increasing the concentration of cannabinoids therefore making it more potent.
Much of these positive metabolic processes can be most effectively begun with thourough flushing and stripping of the plant before harvest. This will help reduce the amount of time necessary for a good cure.
Curing will not only improve potency, but the color and look of most cannabis buds because as the chlorophyll is broken down purple, gold, and white coloration can emerge and the trichomes will appear more pronounced.
Some decarboxylization will take place during curing as well. This happens when the carboxyl group (COOH) located at C-2, C-4, or the end of the hydrocarbon chain at C-3 is destroyed leaving a hydrogen attached and liberating CO2.
Decarboxylization is necessary to convert cannabinoids to usable psychoactive forms; the plants (and your body) carboxylize cannabinoids to make them more soluble in water (for metabolic reactions and excretion). As decarboxylization occurs, the loss of CO2 will liberate a small amount of inert material making the pot more potent via concentration of the cannabinoids.
Taste & Odor
Terpenoids are the highly volatile compounds that give marijuana much of its’ characteristic odors, and therefore tastes.
The most current research also suggests terpenoids lend to the high, sometimes very significantly. Cannabinoids are phenolated terepenes so it’s not surprising that many hundreds of different terpenoids are synthesized as well.
As pot ages, some of the terpenoids go through polycyclic aromatization in the process of decomposition. This agglomeration of terpenoids will change the flavor; hence the ability of cured pot to show flavors that didn’t seem present in the original fresh material. Much of the very volatile terpenoids will also evaporate and or decompose, especially with prolonged curing or storage. This action will remove some matter from the pot increasing the cannabinoid concentration and therefore potency.
A little background on what happens inside and outside the harvested drying plant will help you understand why proper drying and curing are so important to good quality dope. Drying evaporates most of the 70-75 percent water content in fresh marijuana. Drying also converts THC from its non-psychoactive crude acidic form to its psychoactive pH-neutral form. Every THC molecule must shed their moisture content before they are fully psychoactive. In other words fresh green marijuana will not be as potent as dried marijuana.
When you cut a plant or plant part and hang it to dry, the transport of fluids within the plant continues, but at a slower rate. Stomata, small openings on leaf undersides, close soon after harvest and drying is slowed since little water vapor escapes. The natural plant processes slowly come to an end as the plant dries. The outer cells are the first to dry, but fluid still moves from internal cells to supply moisture to the dry outer cells. When this process occurs properly, the plant dries evenly throughout. Removing leaves and large stems upon harvest speeds drying, however, moisture content within the “dried” buds, leaves and stems is most often uneven.
Quick drying also traps chlorophylls and other pigments, starch and nitrates within plant tissue, making it taste “green” burn unevenly and taste bad. Taste and aroma improve when these pigments break down. Slow even drying – where the humidity is similar inside and outside the foliage – allows enough time for the pigments to degrade.
Drying bud converts crude acidic THC from its nonactive form into a neutral pH psychoactive substance. Each THC molecule has to lose it's moisture content in order to become fully psychoactive. When the water exits the bud, the THC becomes slightly different in molecular structure.
Cured buds undergo a:
Reduction in Chlorophyll content,
Reduction in plant starch content,
Reduction in nitrate levels,
Loss of moisture,
Loss of volitile terpenoids, and the polycyclic aromatization of other terpenoids.
All of these phenomena reperesent a loss in weight, and gain in net potency (except for the polycyclic aromatization of terpenoids which affects flavor).
From Mel Frank and Ed Rosenthal- THE marijuana GROWER'S GUIDE
Once the marijuana plant is harvested, it ceases to produce cannabinoids and resins, and the main changes in potency that occur are degradative. However, when the material is handled carefully, dried or cured properly, and then stored well, little degradation will occur. During drying or curing, the resin content may seem to increase, as the plant's tissues shrink away from their resinous coating.
More than 70 percent of the fresh weight of the plant os water. Drying is done to evaporate most of this water, so the marijuana will burn evenly and smoke smoothly. Additionally, the cannabinoids in fresh plant material are mostly in the acid forms, which are not psychoactive. The acid cannabinoids decarboxylate (they lose the gas, carbon dioxide) during the drying or curing processes, which convert them to their psychoactive neutral forms. Decarboxylation is complete if the marijuana is actually smokes.
Cure Your Medicine- Proper curing can exponentially increase the quality and desirability of your harvest. The key word to remember is "slow".

There are also articles in Cannabis Culture Mag and High Times by some very well respected breeders, I couldn't find them online but they are out there somewhere.

KiloBit is a fictitious character from the comic WooHoo.....all pictures are CS2 creations with the intent of artistic expression..
dialog is fiction as well....
First joint of the day tastes bland and uninspiring
I do wonder if i've just got bored of the taste, if you have roast beef every day for three weeks it's going to get dull i suppose.
Still can't shake this worry that i'm going to end up with a jar of tasteless bud...

Around 7-10 days drying then into the jar almost two weeks ago, burped twice a day for at least 15 minutes, also took the buds out for an extra night on the drying shelf early on.
They were pretty dry before going into the jar, some stems snapped easily, others were still a bit bendy.
