For this reason, it is advisable to check every day to make sure the germination medium remains moist, especially if a heat source is used to achieve a higher temperature and therefore a better germination rate; the heat will cause the substrate to dry more quickly, something that must be kept in mind to avoid nasty surprises. In case of hydroponic cultivation it is always better to germinate in rock wool cubes, which of course must always remain moist.
Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.
Leaving seeds to germinate for too long
In addition, the scarce space between the plants will also mean they will compete for available light, something not recommended if we want to get the most out of each plant. The plants will produce very little lateral branching, and will center their growth on a weak main stem, with too long an internodal distance, factors that usually affects negatively on the final yield of buds.
By placing the seed in a moist culture medium, it begins a series of reactions that will lead to germination in a few hours or days. Whichever substrate we choose for germination, we must ensure that it never completely dries out, because as the seed stops absorbing moisture, it’s likely that the seed will cease its activity and never germinate.

To avoid these problems it is be best to sow the seed at about 2cm depth. In addition, we can cover the lower stem as the seedling grows, so that it gains stability and produces new roots along the length of stem we have buried. In this way we can accelerate the growth of the plants.
Now gently extract the seed from its original home with a pair of tweezers making sure to touch only the shell and not the root (the root is the most sensitive part)! Now lay the seedling in the middle of your newly split open Rapid Rooter and gently close the plug around it again.
When Should I NOT Do Surgery?
When you see your seedling looks like this, where the part of the root exposed to the surface already looks green like a stem, you don't need to do anything.
The first thing to do is get a new Rapid Rooter. Since your seed already has a relatively long root, cut the plug open lengthwise so you can gently place the seedling inside in the right position without having to "push" down on the seed.
The cotyledons unfurl and then the regular cannabis leaves between to grow. Here's another view of that same seedling from above only a few hours later. Even though it may have looked a bit weird at first, this seedling is completely normal and will grow just fine from now on!
Other people in this thread seem to think that it’s a good idea to plant the seed as soon as it cracks..however this can be a bad idea..the tap root is what gives the plant its early root structure..and strength..allowing them to have this before planting gives the seedling a much better chance to survive any problems it may encounter in the soil..remember..soil is a living organism and has bacteria..a seed may get halted in its early growth by encountering any numbers of chemical reactions including chlorine shock..pests..or fungus..the ones with a half inch tap root..seem to be able to cope better..
gently place the seedling tap root down and gently push some soil in around it and then cover it gently with some more soil ( make sure you use regular potting soil with a decent amount of peril it in it..I like shultzs potting soil) spray (water @ 6.5 ph) the soil till it’s dark and wet but not puddling..place the potted plant under a 1300-2600k daylight (for vegging cycle) CFL..about 3 – 4 inches from the pot ..in about 2 days or less you will see your new seedling popping through the soil..if it takes 3 days I will be surprized..keep checking the seedling about 3 times a day..make sure to fine mist spray the soil and keep it dark..as the light will dry it out..don’t let it dry out until your plant gets about 4 inches and has its first real growth leaves..
the best thing is to let the seed develop a tap root to a length of about a half inch. I am also going to recommend and assume that you knew enough to let the seed(s) bob around in a glass of water that was allowed to sit for a few hours (to allow chlorine to gas out of the water. before putting the seeds in). and then put the glass of water and seeds into an empty drawer somewhere where there are no lights..and leave it there for 12-14 hours.."longer will risk drowning the seeds"..then you should have triangle folded a and dampened brown coffee filter..not white..white ones may contain bleach..which is also chlorinated..put the coffee filter triangle in a small tray and put the seeds very gently onto the filter.."don’t squish them or they will die"..after their soak they are delicate..so do this carefully..put a "once folded" coffee filter on top of the seeds..and wet it ..
you will see the outline of the seeds through it slightly once it’s wet..put the tray back in the drawer and use the water in the cup to wet the top filter a couple times each day..DO NOT LET THE FILTER DRY OUT BUT ALSO DO NOT LET THE SEEDS SIT IN A PUDDLE..after about three days the tap root will be around a half inch on the seeds..if not leave them until they are..once the seeds are ready..plant them each in their own small 4 inch pot by poking a whole down about an inch with a chopstick or your finger..
Then water the soil as you would with regular plants..allowing the soil to almost dry out up to an inch below surface..I usually water when I see the edges of the soil pull away from the pot sides..but for the seedling when it is still just in the baby leaves..keep the surface damp ..by watering or checking it every few hours..keep a light breeze (fan) circulating in the room..not directly on the plants though..especially when they are little. good luck
