Hello and welcome to my first grow. I purchased 3 seeds of Sensi Seeds' Jack Herer and got 3 other seeds as a gift, but this diary shall focus on the Jack Herer. I'll try to keep these comments short. So here a quick overview: Strain(s): - 3x Jack Herer by Sensi Seeds (Feminized) - 2x Chocobang by Delicious Seeds (Feminized) - 1x Banana Frosting by Sensi Seeds (Feminized) Light (Vegetation and Flower): - Mars Hydro SP 3000 (300W LED) Tent: - Mars Hydro 120x60x180cm (2x4x6') Airflow: - PK 360 cbm/h ø125mm Soil: - Plagron All Mix Nutrition: - BioBizz (BioGrow, BioBloom, FishMix, Root Juice) I put them all between wet paper towels and all germinated after 24-36h. For now they are going to stay in the dark in a mini greenhouse until they sprout.

I'm trying to keep the humidity in the mini greenhouse high by spraying water onto the plants and the inside of the greenhouse itself. The water contains BioBizz Rootjuice 4ml/L The seedlings are looking fine and are standing on the windowsill and getting only sunlight for now.

The week started quite well. I put them into the tent, running the SP 3000 at 50% and 50cm distance and the seedlings were growing nicely. But after a few days I noticed that the Jack Herer started to grow faster then the other strains. First I thought it's because of the genetics, but during my daily check I saw a big fat grub in the soil. I assumed that the potting soil must be infected. I searched for some information online and found out that those critters are eating roots. So I decided to repot every plant into fresh soil, although they are still very small and sensitive. I tried to be as carefully as I could removing all of the old soil but the roots are so fine that a bit of damage could not be avoided. But I was right to do so. While repotting I found a lot more of them, especially in the two Chocobangs and Banana Frosting. Their roots were much less developed than the Jack Herer's, where I have not found a single grub. I hope the little plants are going to recover. We will see. Update: One of the Jack Herer was fimmed. Maybe a bit early, but I want to try things out. So far she is doing a great job in recovering. I hope I have not missed the fim, lol. The Jack Herers lost maybe a week of development because of the mess up with the grubs and the very early repotting, the other strains lost probably even two due to the fact that the grubs damaged their roots. I was worried about one Chocobang and the Banana Frosting, but actually they are recovering just fine as I can notice a lot of new root growth at the bottom of the pot. From now on I am very optimistic in the next weeks of watching them getting bigger!

The third week is almost over and the ladies are looking way better than last week. They completely recovered from the grub incident and are growing faster and faster. It seems like I really missed the FIM -.- I just haven't removed enough from the main trunk and it is just growing as if nothing had happened. Only the leaves are looking quite messy. But, no problem, it was our first time and we just try it again. Hopefully I didn't remove too much this time. The light intensity was increased from 50% to 75%. I water them every other day, adding some root juice and Acti-Vera. Soon, I'm going to FIM/TOP the rest of the plants in preparation for LST and SCROG. Stay tuned.

Again, a week has passed. I repotted the plants into their final 15L/4 gallons shoes with Plagron All-Mix. Plants are looking fine, not perfect, but okay. It feels like they are a bit overwatered and/or very slightly overfed because of the All-Mix. For now, I reduce the watering by 50%. Furthermore, I did a FIM on another Jack Herer (#3). The first FIM I did on JH#1 is looking to work out perfectly, as I can see the development of four new stems (check out the pictures). Great! The SP 3000's intensity was increased to full power, it's very bright. I am happy with the quality of the light. It does what it was built for and does it very well. Temperature and humidity stats are looking perfectly so far. I hope it stays like that, the days are getting warmer as summer comes our way. But my ventilation is currently running on intensity level 1/5, so we still have some room for maneuver. In addition, I will get a second oscillating clipfan soon. Next week I plan to FIM plants that have not been FIMed yet and let them recover. By then, most of the stress for the plants should be over and I can let them grow in peace. Stay tuned!
