Okay, you got all of your seeds planted in their nice clean cups, perched atop their heating mats that are keeping the soil nice and consistently warm for their weed seed germination process, what do you do at this juncture? You guessed it, bring on the light. Whether you are doing an indoor grow, or an outdoor one, it is now time to get the heavy duty light action going. AT this phase you want the lights on for 16 to 20 hours, and off for only four to six. You are convincing the seeds that now is the time, the more light, the better. DO NOT, however, do a constant light cycle, that is a mistake. Make sure that after your initial watering immediately after you planted the seeds that they still have at least one eighth of an inch of soil covering their rounded tops. After their initial watering which immediately followed their transplant into the germinating soil, do not water again for at least 24 hours. Keep the soil and germinating chambers warm, keep the lights on for the recommended cycle, and not too close to the tops of the solo cups, and keep your hands off the watering can. Let these marijuana seed babies do their thing without being drowned. Yes, you can drown a seed, so take my advice, do not re-water again for at least 24 to 48 hours.
Watch the pot seed germinating process like a hawk.
No, this does not mean that you have to set up a camera in the grow room, although I know some people who have. Be patient, and if you have to water within 48 hours, do it with a spray mister, You do not want to disturb the soil on top of the seed, that is an important layer of soil for your pot seeds to have covering them. To test whether or not things are dry enough to water in the pot seed germinating process, stick a toothpick about an inch into the soil (as far away from the seed as possible). If it comes out with soil clumped all over it, you are probably moist enough. If it comes out dry, go ahead and add a little bit of water from your misting or spray bottle. Again, sit back and be patient with these seeds, they are busy in there, you just can’t see it.
