Frozen Black Cherry (Anesia Seeds)

Jacks_Pot I marked 07/12/25 as the first day of growth. The plan is to let them grow for 4 weeks, depending on how well they do. The four best plants will remain. As always, I’ll be scrogging. I set the COB wattage to 60 watts at a distance of 45 cm. This resulted in a DLI of 20 / PPFD 309. Even though I’m already giving quite a bit more light than the DLI chart suggests (the chart says to start with a DLI of 13; I’m giving 20), they still stretch during the first few days. Not really a problem, since I’ll fix that when transplanting. Still strange how they always stretch in those first days… This week, on day 3, I gave each plant 30 ml of tap water lightly fed with CannaStart and Rhizotonic (0.75 ml of each per 500 ml) (EC 1.08 – pH 6.2 – 19.9°C). On day 5, I gave them another 40 ml of the same nutrient solution. On day 7, I made a bit more nutrient water with 0.5 ml CannaStart + 0.5 ml Rhizotonic per 250 ml (EC 1.18 – pH 6.2 – 20.6°C). Each plant received 45 ml of this. I also placed a small fan to make the seedlings gently sway. The heat mat was set to 25°C. Temperatures fluctuated between 20.2 and 25.0°C, and humidity stayed between 38 and 60%. C u next week!

Jacks_Pot The little ones were making good progress and were right on schedule. On day 13, four were transplanted into 14-liter Airpots. The potting soil was again from DCM (Vegetables and Herbs) and was watered in with Power Roots (4 ml / 4000 ml) and nematodes against fungus gnats. The small heat mat was replaced with the large Root!T heat mat (60 watts). This is what the feeding schedule looked like this week: Day 8 → Dry Day 9 → To 250 ml of tap water, 0.2 ml Pure Zym, 0.2 ml Power Roots, 0.75 ml Fish Force, 1 drop of Silic Rock, and 1 drop of CalMag were added (EC 1.19 – pH 6.0 – 20.5°C). Each plant received 30 ml. Day 10 → Dry Day 11 → To 300 ml of tap water, 0.2 ml Pure Zym, 0.2 ml Power Roots, 0.2 ml Terra Grow, 1 drop of Silic Rock, and 1 drop of CalMag were added (EC 1.37 – pH 6.1 – 21.1°C). Each plant received 50 ml. Day 12 → Dry Day 13 → Transplant day Day 14 → Dry The lamp wattage remained at 60 watts, but the distance was reduced to 43 cm. This resulted in a DLI of 22 / PPFD 340. On day 13, the second COB lamp was placed in the tent. Together they provided 120 watts at a distance of 48 cm. This also resulted in a DLI of 22 / PPFD 340. Temperatures fluctuated between 19.2 and 24.1°C, and humidity stayed between 35 and 59%. Soil temperature was around 20–22°C. The humidity was actually too low for this stage, but I decided to try a grow phase without a humidifier. I do notice that they grow more slowly than with higher humidity. C u next week!

Jacks_Pot This week went smoothly, with no signs of deficiencies. The plant on the right is slightly larger than the rest. In the other plants, the nodes are fairly close together, while in this one there is a bit more spacing. That doesn’t really matter, because during the scrogging they will (hopefully) end up at roughly the same height. The four lowest shoots were removed on each plant. The next four shoots above those will become the four main branches. Normally I go for six main branches per plant, but with four I’m hoping for better overview and less of a jungle. So tomorrow or so they will be topped. This is what they received this week: Day 15 → To 2500 ml of tap water, 10 ml Fish Force, 0.3 ml Silic Rock and 0.3 ml CalMag were added (EC 1.25 – pH 6.0 – 20.5°C). Each plant received 600 ml. Day 16 → Dry Day 17 → To 2500 ml of tap water, 2 ml Pure Zym, 2 ml Power Roots, 3.5 ml Terra Grow, 0.3 ml Silic Rock and 0.3 ml CalMag were added (EC 1.30 – pH 6.1 – 20.2°C). Each plant received 600 ml. Day 18 → Dry Day 19 → Same as day 17 (EC 1.25 – pH 6.0 – 20.2°C). Each received 600 ml. Day 20 → Dry Day 21 → Same as day 17 (EC 1.25 – pH 6.0 – 20.5°C). Each received 600 ml. On day 18 they received their first spray with Vita Race (0.5 ml / 150 ml). I apply this about half an hour before the lights turn on. The exhaust and fan are switched off during this time so it doesn’t dry too quickly. The wattage of the COBs was increased to 130 watts at a distance of 39 cm. This resulted in a DLI of 26 and a PPFD of 401. Temperatures ranged between 18.3–24.2°C and humidity stayed between 24–58%. I ended up connecting the humidifier after all, as it became very dry in the tent (values below 20%). C u next week!

Jacks_Pot Normally, I was planning to switch to 12/12 after 4 weeks, but I still find them too small. So I’m going to keep them on 18/6 for a few more days. The week started with topping the plants. As I mentioned in the previous update, I will keep 4 main branches per plant. On day 28, the scrog net was installed. Apart from that, the week went smoothly with no deficiencies as far as I can tell. They are drinking more now, though. The fungus gnats are under control, with 0 specimens on the yellow sticky traps. This is what they received this week: Day 22 → Dry Day 23 → To 2500 ml of tap water, 13 ml Fish Force, 0.5 ml Silic Rock, and 0.5 ml CalMag were added (EC 1.38 – pH 6.0 – 20.5°C). I gave each plant 600 ml of this. Day 24 → Dry Day 25 → To 3000 ml of tap water, 2.5 ml Pure Zym, 2.5 ml Power Roots, 2 ml Sugar Royal, 5 ml Terra Grow, 0.6 ml Silic Rock, and 0.6 ml CalMag were added (EC 1.41 – pH 6.1 – 20°C). I gave each plant 750 ml. Day 26 → To 3000 ml of tap water, 5 ml Terra Grow, 0.6 ml Silic Rock, and 0.6 ml CalMag were added (EC 1.34 – pH 6.1 – 20.5°C). I gave each plant 750 ml. Day 27 → Same as day 25 (EC 1.44 – pH 6.1 – 20.8°C). Each plant received 750 ml. Day 28 → Same as day 26 (EC 1.27 – pH 6.1 – 20.5°C). Each plant received 750 ml. On day 25, I gave them their weekly spray with Vita Race (1 ml / 200 ml). The wattage of the COBs was increased to 140 watts at a distance of 38 cm. This resulted in a DLI of 31 / PPFD of 478. Temperatures ranged between 18.9–23.8°C, and humidity stayed between 26–67%. Humidity is still low when the humidifier is not running, but it is now less of an issue when it occasionally drops too low. C u next week!

Jacks_Pot This week lasted only 6 days. Tomorrow I will switch to the 12/12 light schedule. If it had depended on the plant on the right, I would have switched earlier, but the other plants were progressing less smoothly. Hopefully the scrog net will get filled, and at the same time I want to prevent them from stretching too much. In total, they were allowed to grow for 34 days on 18/6 (the 4 days of germination not included). Apart from that, the week went without any problems and I think they are feeling quite good. This is what their feeding schedule looked like: Day 29 → To 3000 ml of tap water, 18 ml Fish Force, 1 ml Silic Rock, and 1 ml CalMag were added (EC 1.48 – pH 6.0 – 20°C). I gave each plant 750 ml of this. Day 30 → To 3000 ml of tap water, 2.5 ml Pure Zym, 2.5 ml Power Roots, 2 ml Sugar Royal, 7 ml Terra Grow, 1 ml Silic Rock, and 1 ml CalMag were added (EC 1.71 – pH 6.0 – 20.2°C). I gave each plant 750 ml of this. Day 31 → To 3000 ml of tap water, 6 ml Terra Grow, 1 ml Silic Rock, and 1 ml CalMag were added (EC 1.46 – pH 6.1 – 21.2°C). I gave each plant 750 ml of this. Day 32 → Same as day 30, but with 6 ml Terra Grow (EC 1.59 – pH 6.1 – 20.9°C). Each received 750 ml. Day 33 → Same as day 31 (EC 1.40 – pH 6.1 – 21.2°C). Each received 750 ml. Day 34 → Same as day 32 (EC 1.57 – pH 6.1 – 21.2°C). Each received 750 ml. On day 32, they received a foliar spray with Vita Race (1.2 ml / 250 ml). The wattage of the COBs was increased on day 29 to 160 watts at a distance of 38 cm. This resulted in a DLI of 37 / PPFD of 571. The average power consumption of the COBs during the vegetative phase was 111 watts (maximum was 160 watts). Temperatures fluctuated between 19.1 and 24.2°C, and humidity remained between 34 and 68%. C u next week!

Jacks_Pot On the first day of this week, I removed a few leaves at the top to allow more light to reach the center of the plants. Later in the week, pruning and defoliation were also done below the scrog net. I actually like having 4 main branches instead of 6. There is now more clarity underneath the net, yet it still fills up nicely. They have become thirstier again, as 750 ml per 24 hours was no longer sufficient. They now receive about 1000 ml. Only the plant on the left drinks a bit less and is still fine with 700 ml. The scrog is also progressing well, and the plants are already starting to give off a scent. This is what their feeding schedule looked like: Day 35 → To 3000 ml of tap water, 20 ml Fish Force, 1 ml Silic Rock, and 1 ml CalMag were added (EC 1.60 – pH 6.0 – 19.8°C). I gave each plant 750 ml of this. Day 36 → To 3000 ml of tap water, 3 ml Pure Zym, 2 ml Power Roots, 2 ml Sugar Royal, 6 ml Terra Grow, 3 ml Power Buds, 1 ml Silic Rock, and 1 ml CalMag were added (EC 1.64 – pH 6.1 – 20.2°C). I gave each plant 750 ml of this. Day 37 → To 4000 ml of tap water, 10 ml Terra Grow, 1.2 ml Silic Rock, and 1.2 ml CalMag were added (EC 1.55 – pH 6.1 – 20.1°C). I gave them 1000 ml each; the left plant received 700 ml. Day 38 → To 4000 ml of tap water, 4 ml Pure Zym, 2 ml Power Roots, 3 ml Sugar Royal, 8 ml Terra Grow, 4 ml Power Buds, 1.2 ml Silic Rock, and 1.2 ml CalMag were added (EC 1.59 – pH 6.1 – 21.2°C). I gave them 1100 ml each; the left plant received 600 ml. Day 39 → Same as day 37 (EC 1.59 – pH 6.1 – 20.5°C). Each plant received 1100 ml; the left plant received 700 ml. Day 40 → Same as day 38 (EC 1.58 – pH 6.1 – 21.1°C). Each plant received 1100 ml; the left plant received 700 ml. Day 41 → Same as day 37 (EC 1.58 – pH 6.1 – 21.1°C). Each plant received 1100 ml; the left plant received 700 ml. On day 39, they were sprayed with Vita Race (1.5 ml / 300 ml). The wattage of the COBs was increased to 170 watts at a distance of 38 cm. This resulted in a DLI of 28 and a PPFD of 648. I set the circulation fan to setting 2, and the exhaust fan was also increased slightly. The humidifier was turned off. C u next week! Temperatures fluctuated between 18.3 and 25.1°C, and humidity remained between 38% and 72%.
