Original Sour Diesel - coco grow

Light power consumption: 82 watt Hi there fellow growers! As stated in the previous update, Monday October 10 2022 is day 1. On day 2 I removed the humidity dome and installed the LED light, about 85 centimeter above the seedlings and fully dimmed. Also, I fertigated for the first time, with a light seedling mix (at a little under 0,6 mS/cm, while tap water is around 0,45 mS/cm). I skipped fertigating on day 3, to dry out the medium a bit and stimulate root grow. Since day 4, I’m fertigating daily and increased EC little by little and at the end of the first week, I was fertigating at 0,7 mS/cm. At that point I dropped the light 10 centimeters down to 75 centimeter, as they looked a little bit leggy to me. Also, I buffered another coco brick. The procedure takes a few days and I plan on transferring them to 2 L AirRap pots in the beginning of the second week. The ‘recipe’ I used is as follows: 1. Rehydrate coco brick as instructed on package; 2. Rinse the coco thoroughly, about 1 L at a time in a colander with smaller than average holes. This way, the smallest particles will be flushed away; 3. Put the rinsed coco in a fabric pot and place it in a bucket with tap water mixed with a high nitrogen calcium supplement at 1,5 mS/cm. My tap water is pH 8,2 so I lower it to 7,0, but I don’t think that’s necessary. The coco should be fully submerged in the water; 4. After 24 hours, renew the solution, but this time I use a low nitrogen calmag supplement. I let the coco soak for another 24 hours; 5. Next up, I take the fabric pot out of the bucket and put it on a rack above another bucket, so it can drip out. I let the coco rest for 24 to 48 hours; 6. Next, I rinse the coco while in the fabric pot. I use tap water pH’ed down to 6,2 and slowly pour in the water. I monitor the EC of the run off and it usually gets from above 1,0 mS/cm to around 6,0 mS/cm after a few liters. The coco is now ready to use; 7. During all the waiting, I also rinse the perlite, using the same colander. There’s a lot of white dust and the water running through is white at first, but after rinsing it, the run off water becomes clear. As is tradition, I named the girls: Roxanne, Sophia, Tiffany, Ulrika and Vivian. One sister does indeed not have a name. Even after a week, she still has her helmet firmly attached to her cotyledons and I’m unable to remove it without severely damaging her. She still grows (very slowly) though, so as an experiment, I’m going to keep her a while longer. Anyway, she will not make it to flower, hence, I didn’t giver her a name. Today (day 8) I transferred the five sisters to 2L AirRap pots, but this will be covered in the following entry in this diary next week. Also in next week’s report: a proper individual introduction of the five ladies. Thanks for stopping by and happy growing!
