D0: Filled the glass with water and let it rest overnight to evaporate the chlorine
D1: [23° 62%] Dropped the seed to the water and put it in a closet to rest. The temperature there is more stable than outside since there is a cold front arriving so the temperature is falling. Prepared the soil with all the organic fertilizers and put it in the 7L container to rest till the transplantation day. Let some space to put the inert soil later when transplanting the germinated seed to reduce the shock it would have in a rich soil. Also prepared a liquid solution of NPK 20-5-20 with solid crystals so that they dissolve in case I need to bump the nutrients during veg phase. It's currently at 526ppm.
D2: [25.8° 79%] After 20h resting in the water, moved the seed to the moist paper tower and will check again in about 12h. Put a cotton coat around the box to keep it dark and improve the temperature stabilization since today got colder and the temperature is fluctuating a little bit. The water coming out of the soil mixture is 464ppm and the liquid nutrient solution is still at 526ppm. Added some more NPK to the solution to elevate it a little bit more.
D3: [21.6° 92%] 24h since moved the seed to the moist paper and no signs of any radicle. The temperature dropped and I am worried that this is too close to the lower range for germination. Looking into a way to put a light bulb to warm the box a little bit till the cold front passes. The run off water from the soil mixture is at 528ppm and the liquid nutrient solution is now at 773ppm. Added a small amount of NPK to the solution to try to reach 900ppm.
D4: [21.3° 93%] 48h since moved the seed and no signs of radicle. Getting anxious and worried that the low temperature is messing my germination. Soil run off water at 395ppm and liquid nutrient solution at 873ppm.
D5: [21.4° 90%] 72h and no radicle. Freaking out. Trying to keep the box close to the light bulb to warm it up. It is now getting to 25-27° and I will try to keep it during that range over the day. The weather is predicted to warm tomorrow and forward so I hope I wont need this workaround anymore. I tried my best to keep the seed at total dark in this new setup but I am now worried that any light might be leaking in because of the near light bulb. The soil run off is at 559ppm and the liquid nutrient solution is at 943ppm.
D6: [- -] Have changed the setup to polystyrene box and warmed water to keep the temperatures around 27°. Took a lot of measures during the day and the temp was always in the range 25-29°. Still no signs of germination. Stopped taking measures of soil and liquid solution since they are around the targeted values. Will get back to that when I get a germinated seed.
D7: [- -] The new setup is way better and the measures were always in the range 25-29°. Still no signs of germination. Gonna put the seed in the warm water for a couple of hours to soft the shell again as a last resource. Feeling really low right now since this is the first attempt 😞
D8: [- -] No success with the first seed. Losing my hopes there. Added a second seed to the water cup to start all over again. Bought some mineral water to use instead of the tap to see if it makes any difference. Also added some drops of peroxide as recommended by some growers to help in this initial phase. The weather is now hot and the temperatures all day are around 26-27° so I dont need to worry about warming the box anymore.
D9: [- -] Left the second seed all day in the water glass. Kept adding water to the first seed paper towel but no success.
D10: [- -] Will let the second seed all day in the water glass and check on evening. Moved the first seed back to a new water glass with peroxide too as a last attempt to germinate her. Feeling beated 😵
D11: [27° 63%] FINALLY HOPE! I checked my second seed last night after around 36h in the water glass and it was already with a beautiful tail! Moved to the paper towel for the night to grow a little bit more. This morning I checked again and it was ready to be moved to the soil 😍 I am really happy and revigorated now. Have taken some pictures of the setup to start again the daily checks. Let's see how this strong beauty is going forward. Moved the first seed to a some coconut water after staying in the peroxide water overnight. Some growers shared that the nutrients in the coconut water might "revive" old seeds and might be a shot before giving up.
Would you be alright with me offering you some generalized pointers & advice to help you out? So cannabis plants LOVE heat and humidity. It is the buds that hate it, Early in veg we want nice warm temps like 79-84 MAX with lights on and no more than 9 degrees less with lights off. If we allow for too much of a temperature swing between lights on and lights off this will encourage our plants to stretch more than we want them to. So we try to keep those gaps in temperature tight through veg and early flower. When our plants are small, So are their roots. When our plants first start out in seedling stage or young plant stage they generally grow fairly slow because of this. If we introduce some humidity into the environment for the leafs to supplement the roots with some foliar intake we can speed ourselves along through this stalled-out stage of growth. The humidity of 60-70% works great for the first few weeks. If you do not have a humidifier get one they are just as important as dehumidifiers for growing. In the meantime you can also use a bucket full of water with no lid on it will passively raise the humidity up fairly well.
as you are in flower now it is not important but for the next time something to think about for sure. When we are in flower how our buds develop is largely based off our temperature control of the room. If we grow our buds too high of temps we will get huge big buds but they will be very airy and prone to foxtail. You will also lose out on a lot of cake, If we grow them too cold we get extremely dense nugs and very caked but lose out on a lot of size. Density + size is what we want for our weight to be right. Temperature ranges of around 77-80 MAX with lights on and again no more than 9 degrees less with lights off.
Once our plants finish their vertical growth by weeks 4-6 of flower depending on strain and with autoflowers you watch for it by eye, Once this happens now we want to begin to widen our temperature gaps between lights on and off to beyond 10 degrees less and a bit more each week until harvest. This will now instead signal the plant to put extra energy into the budding and resin production. Using light deprevation in the last 2 weeks to simulate cloud cover works well & doing a really cold feed on your last flush before pull down works great too. These are all enviromental triggers to cause the plants to react genetically as to produce the desired traits we wish to draw out of them.
Check out something called Vapor pressure deficit & how it relates to growing cannabis. All new growers should familiarize themselves with it and learn to use a VPD chart and log their rooms numbers every day. If you do not have them yet get yourself a PAR meter and a thermal laser temp gun like the fluke 62 MAX to better read your plants needs and grow to them. If you should need any help please feel free to ask, Just follow my growdiaries profile & shoot me a message! I am currently producing a youtube tutorial series for all levels of growers to utilize.
