gr3g4l First week 18/06h. This week, a heat wave with very high temperatures. One day, the extractor fan stopped working, and the temperature rose dramatically to 43ºC—absolutely insane. The intake fan also stopped working, which caused the extractor fan to stop as well. I follow a nutrient schedule fairly closely, although sometimes the timings aren't 100% accurate, and I end up adding or subtracting too much. I always keep an eye out for over-fertilization, and if I find it, I stop fertilizing for a couple of waterings and reduce the dose. Fertilizers per week. Three waterings per week as a general rule. Substrate: Atami Janeco LIGHT MIX. This time, recycled. Watering: Reverse osmosis water

gr3g4l Second week, 18/06h. This week we added the humidifier to maintain higher humidity. After 14 days, the roots appeared, and I transplanted them into their final 6L fabric pots. A couple of them were discarded since they weren't growing at the same rate as the others. The 74x74x170cm space isn't big enough for many plants, and I prefer to get rid of some. I then increased the LED wattage to 220W. From 150W to 220W.

gr3g4l Week 3, 18/06h. Apical bud pruning on different days. And pruning of the lower branches from the first nodes.

gr3g4l Week 4, 18/06h. After a few days of recovery from the apical pruning, I defoliated the plants, leaving only the tips and little else. I transplanted the two discarded plants, which were in 1L pots, into larger pots and placed them outdoors. This was already well into September.

gr3g4l Week 5, Last week of the grow. On the last day, I removed the humidifier and placed the plants in their final location where they will spend, or should spend, the rest of the days.

gr3g4l 6th Week 1st 12/12h Increase power from watts up to 300W and little else.

gr3g4l Week 7 2nd 12/12h After about ten days, the first pistils began to appear. This week we had to put the heaters on to make sure the temperature didn't drop too much when the lights went out.

gr3g4l Week 8 3rd 12/12h A quiet start to the week. It's a pleasure to grow such uniform seeds, as if they were cuttings from the same mother plant. We'll see if they remain this uniform after the necessary leaf and sucker pruning.

gr3g4l Week 9 4th 12/12h One more week and they'll be ready for fattening. Hard stems, not much internode spacing, and relatively broad leaves. At the beginning of the week, a good pruning of the lower branches and leaves. After 26 days, I realized I had under-planted them, leaving only 6 plants.

gr3g4l Week 10 5th 12/12h At the beginning of the fifth week, I got rid of number 5 due to lack of space.

gr3g4l 11th Week 6th 12/12h. Another quiet week, just another one. A week in which some leaves started showing a different color. For flat-Earthers, a color change is coming. A week in which number 6, bottom right, continued to show signs of albinism at the tips of the apical buds. For whatever reason, this plant decided that the light exposure was too much for it, and it's something I'll have to learn to live with, whatever happens. I distanced the LEDs a bit to try to correct it. Currently, the canopies are about 40 cm from the LEDs, and I increased the distance to 45 cm.

gr3g4l 12th Week 7th 12/12h Formation of beautiful colas and bud fattening Plant #6 continues to show albinism, although it doesn't seem to be increasing in size; it's staying the same. I raised the LEDs 5 cm and it seems to have worked quite well. We're entering a delicate phase, so I added a dehumidifier that turns on when the LEDs are off. Later, I'll add another fan and a dehumidifier that will run 24/7. At night, with the LEDs on, the air is much drier than during the day with the lights off, so I'll leave the fan on for a few more hours during the day—night for the plants.

gr3g4l Early part of the second-to-last week I reduced the amount of watering slightly from 600ml/day to 500ml, thinking they would drink less, but I was wrong and went back to watering as usual until the end of the week when I watered only with reverse osmosis water. Next week I'll water with just water for a gentle flush, so I can harvest them in 60-63 days.

gr3g4l After 61 days, harvest and dry in the closet.

gr3g4l Drying, Weight, and Growing Costs I should have included some additional items like substrate and seeds, but these didn't cost anything this time. The substrate was reused, and the seeds were a gift. This grow consists of a total of 5 plants in 6L fabric pots. The plants are relatively small, about 60 cm tall. Approximate monthly cost: €33 and €0.32 per gram.
