D12: [22.7° 80%] Today I have removed a little bit of the top of the soil because I feel I have planted the seed too deep. I can already see it's top coming out and I am feeling really good about this! The first seed still no luck after all tries =/ guess this is a lost cause.
D13: [24.5° 73%] Today this little beauty is already out and fighting the shell to sprout it's leaves. It is already 2.5cm tall! I will start measuring the temperature during midday too to get a better daily values average for the week since during the morning it's still chill from the night. I will check the first seed at night but I have no hopes =P
D14: [22.9° 78% am] [26.3° 61% pm] On top of the morning measures (am) I started taking temp around 13:30 when the temperatures are the highest of the day too (pm). Today the plant is already 5cm tall and I had to gave her a little help to remove the seed shell since it was still stuck in the first leaves. No luck with the first seed so I will stop posting updates about her... RIP my dear. I got my little lady today for a quick 15min sunbath - at around 217k lumens - and then put some coverage so that she doesn't get burn from the sun. The soil probe is stating the soil is still wet so I just added some water around the center to keep it moist.
D15: [22.6° 74% am] [29° 53% pm] Today this little beauty is already 7.3cm tall. I started taking some poor measures of light intensity during the day using my phone to check if she is receiving enough light. During morning it is in the range 600-3000 lumens and during afternoon when the sun hits the balcony hard it gets around 40k under the protection coverage and 250k with direct sunlight. Since the last I think is too strong for her first week I am giving her 15min everyday and then putting under coverage where the intensity is more pleasant. Today I added 1L of water to the 7L pot and the soil run off was at 195ppm. I have also added a very very small quantity of liquid nutrient around the center before watering, something like <5ml@190ppm to add some nutrients to the inert initial center soil.
D16: [23.9° 76%am] [26.1° 67%pm] Today I let her get a 15min sunbath. Since she is still young and fragile I don't want to let her stay a lot under this hot sun.
D17: [24.3° 76%am] [29° 62%pm] I noticed that she grew a little little bit since yesterday. She is now 7.5cm tall and 2.5cm wide. I am letting her stay under coverage during day because the sun is really strong and it is getting really hot (over 35° under the sun).
D18: [23.7° 72a%m] [30° 55%pm] Today I have added a little bit (<5ml) of 190ppm NPK liquid solution to the soil. After that I added 1L of tap water. The run off water is at 210ppm which I think will be really good for her during these two first weeks.
D19: [24° 72%am] [pm] I added some (<10ml) liquid base nutrient solution (Ca Cu Mg Mn Fe Zn Co Na2MoO4 H3BO3 Na2SeO3) to the soil preparing her to thrive on her second week. She is now 7.5cm tall and 3.5cm wide and her leaves are starting to get bigger. This is the last day of the first week and I am really proud of her growth.
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.
