how hot ca cannabis seeds get

Compost piles that reach and maintain a temperature of at least 140 degrees Fahrenheit for at least two weeks will kill most seeds within the pile. It is important to turn your compost pile so that it composts evenly since the hottest part of the pile is at the center. Seeds left on the outside or bottom of the pile may not reach a high enough temperature to thoroughly kill all of the seeds inside.

Seeds begin to die at temperatures above 108 degrees Fahrenheit, but require longer periods of exposure at lower temperatures. At temperatures below 140 degrees Fahrenheit some species are not affected by heat treatments. The most effective way to ensure that you kill all of the seeds is to heat them to a temperature above 140 degrees Fahrenheit. Seeds mixed into compost or topsoil require higher temperatures and longer exposure times than bare, unprotected seeds.

Compost

Compost, potting soil and other garden amendments can harbor seeds from unwanted grasses and broadleaf weeds. You can prevent unwanted seeds from competing with your lawn and garden plants by using a heat treatment of the right duration and intensity. The exact temperature needed to kill a seed depends on the species of plant it came from, but in most cases heating seeds to 140 degrees Fahrenheit is sufficient to sterilize them.

You can quickly kill seeds and harmful micro-organisms in soil using your kitchen oven. Heating your soil to temperatures between 180 and 200 degrees Fahrenheit will kill any seed in the soil after 30 minutes. The best way to heat treat your soil is to place it in a pan in the center of the oven. Make sure that the soil is about 4 inches deep so that it heats evenly. You can monitor the temperature of your soil using a standard oven thermometer.

Heating your soil above 200 degrees Fahrenheit can cause certain types of soil with a concentration of organic matter to release a foul odor. In some cases overheating your soil can also begin a chemical reaction in the soil that will release a chemical that is harmful to plants. Large compost piles in excess of 7 feet in height that are heated to 200 degrees Fahrenheit or higher may combust. The optimal temperature for creating compost and killing seeds is between 130 and 150 degrees Fahrenheit. You can monitor the internal temperature of your compost pile using a temperature probe. If your compost pile begins to overheat, cool it off using water, reduce the size of the pile or add a bulky material such as wood chips.

Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Was the seed found in good weed?

Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.

Another common mistake, in this case when germinating in kitchen paper or similar, is to let the seed germinate until the cotyledons appear. If we do this, then the subsequent transplant is very difficult, and it is very likely that we’ll damage the root in the attempt. Additionally, the longer the root is exposed to air and light, the more damage will result, so it is preferable to transplant it before this occurs.

The paper towel should never dry out once germination begins

Leaving seeds to germinate for too long

Although it may be tempting, germinating several seeds in the same container is not usually successful. In addition to the difficulty of correctly planting several seeds in the same pot, once they are born they will compete for the little space available for their roots. Having restricted root growth does not suit cannabis plants, which will grow more weakly and with greater internodal distance.

Although the germination of cannabis seeds is a relatively quick and easy process, it is crucial to take into account a series of important factors in order to obtain as high a germination rate as possible. In addition, it’s in our interest that the seeds germinate as quickly as possible, and especially if we want to avoid problems like fungal infection or a low germination rate.

Too often the seed is buried too deep (a problem that we have already seen in case of watering after planting the seed), so the seedling may never emerge. In the other case, if we sow too close to the surface, we can find that the seed germinates well but the stem grows weak, bending and not allowing the seedling to develop correctly.
