White Widow/Veg 0.60x0.80/Flora 1mtx0.80

cultivodelfuego Finally, on 11/19, after weeks of waiting, the Cultivarg 80x2 tent arrived, and I couldn't be happier. Metal frame, good quality zippers, fabric, passive intake vents, and various intake/extraction holes in both the flowering and vegetative spaces. On the same day, 5 cuttings of White Widow (3 from pheno 1, 1 from pheno 3, and 1 from pheno 4) and two little plants in their first weeks of life from regular seeds, taken from a hermaphrodite mother, arrived thanks to @Surhaze (ig). A cutting of River Haze from Silver Seeds will be arriving soon. I set up the ventilation system, which runs all the time during light hours and 15' on / 15' off during dark time: a TT Max 125 GHP 5" turbine at maximum speed (290 m3/h) for extraction // Profan Inline 125 GHP (190 m3/h) 5" for intake. I've been keeping the daytime temperature between 22º and 25º and at night between 17º and 19º. I usually keep the room heating to a minimum to prevent it from dropping. I'm not having much luck with humidity, though. It tends to stay between 40% and 50%, rising a bit to 60/62% when I do a foliar spray and dropping at times to 35%. I put the diffuser caps I took from the greenhouses with water, but it doesn't seem to be having much effect. The main light for the flowering tent hasn't arrived yet, so I had to temporarily set up the vegetative area with the greenhouses that arrived at the same time as the tent. I started by assembling the lamp holder for two, as seen in the first photos. Then I added the third light and removed the diffuser plastic, as tests done on this type of lamp with a quantum meter by henki duken showed that the PPFD goes from 117 µmol to 238 µmol. On 11/21, I transplanted 4 of the cuttings (2 pheno 1, 1 pheno 3, and 1 pheno 4) into 5-liter Mad Rocket pots. One pheno 1 cutting that was a bit droopy at the time of transplanting is still pending transplant, along with the two regular seeds, which I will do tomorrow. The substrate is Super Mix from Santa Planta. After the transplant, I watered with Amazonia, the rooting agent from Namaste Nutrients, prepared using 1 g/lts. in dechlorinated water (72 hrs) with pH 6 (for the next waterings, I will use pH 5.5 and increase it by one-tenth each week). I didn't measure the EC since I still don't have the battery for the meter. There are some signs of stress from the transplant, although they improved quite quickly from the initial droop. I still can't determine if the lower leaves that are drying/yellowing are due to a lack of nitrogen from having to wait in the cup for so long until the tent arrived, causing the depletion of available nutrients, or if there's some other problem. There are also some leaves with burns whose cause I don't know: in some, it's just the tip, while in others, the damage is a bit more severe. I hope that as the days go by, the burn doesn't progress and they show signs of improvement. UPDATE: On 5/25, I transplanted the remaining ones into the 5-liter Mad Rocket pots. For these three, unlike the previous ones, I added the mycorrhizae directly into the substrate instead of in the watering. Once the substrate was in the container where I do the transplants, I sprinkled mycorrhizae as I mixed and moved the substrate to ensure they were well distributed and that there were no clumps. Once the pot was full, I dusted mycorrhizae into the hole made for placing the root ball. I reduced the amount of water in the watering from 750ml to 500ml.

cultivodelfuego This week I was doing some tests with the amount of watering. I was doing a single watering per week with 750/1000 cc pH 6, but given the size of the plants, to avoid over-watering I decided to lower the amount to 500cc. When they needed a little more water, I misted to barely moisten the substrate. With the intention of improving the humidity (which was between 25% and 35%), I was spraying the walls of the tent, but as we know, this has a short-lived effect. Next week I’m going to add a humidifier. They still have a somewhat yellowish color, which as I mentioned last week I think is due to them waiting too long in the cup before transplanting and they were short on nitrogen in the little substrate they had. I was hoping that with the transplant to the new substrate it would improve, but it seems that the nutrients are still not available. I started fertilizing with Oro Negro (NPK + (FE) 0.10%, (S) 0.6%, (Ca) 0.5%, (Mn) 0.3%, (Cu) 0.2%, (B) 0.25%, Organic Matter 86%) at a concentration of 2 ml/l to see if it improves. A clone has joined the family: A River Haze from Silver seeds in coco mix, taken from a monstrous mother that a friend has in a Mad Rocket of 16 liters: a beautiful size and very well trained with LST. I’m going to leave it for a week and a half to acclimate to its new home and then I’m going to transplant it to a Mad Rocket of 5 liters like the rest of its companions, with the substrate from Santa Planta Super Mix.

cultivodelfuego I'm still waiting for the main light for the flowering tent to arrive, but this week two new members are joining the equipment in the greenhouse: a humidifier and a 5-blade fan to give them some movement. Both have arrived to radically change the conditions of the space and improve the quality of life for the plants. The humidifier has a capacity of 3 liters (approximately 9-10 hours of autonomy at maximum power) and is ultrasonic, so it doesn't cause temperature issues. I placed it in the center at the back of the tent, and since it has two adjustable outlets, I pointed one towards each side wall. I did some tests timing the ventilation and humidifier at different intervals, but since the humidity fluctuated a lot between the moments the ventilation turned on and off, I decided to leave it on all the time as it was before and increased the humidifier's power (it's at 2/3 of its capacity) to maintain a constant 60% (+-1%) humidity. This will require me to fill the humidifier tank more often, but it guarantees consistency. While the ventilation system works perfectly to renew the air in the indoor space, I had been noticing that the stem and branches were thickening slowly due to lack of movement. I figured this could mean problems during flowering if they became too weak, so I added the fan to give the plants some movement and air circulation. I also received a kit of natural insecticides from Eden that I ordered as a precaution to have on hand immediately in case any pests appear: Potassium soap, neem oil, diatomaceous earth, and a preparation against spider mites and powdery mildew based on neem and cinnamon. This week I'm going to keep the watering volume at 500cc but distribute it into 250cc of Amazonia (rooting agent) on Thursday and 250cc of Oro Negro (NPK+) on Monday. With the humidity level in the environment at 60%, I doubt the water will evaporate quickly, but if necessary, I'll spray to moisten the substrate. On Tuesday, I'm going to prepare a solution with neem oil at 1ml/l to make a preventive foliar application when the plants are entering their dark period.
