David_Clark For this grow, I have:
- HighPro Basic Tent 120x120x200
- RDWC 4.1 System – BioProyect
Ventilation
- Profan Garden High Pro Tt 150mm 6 Inch Turbo Extractor (extracts air from the tent)
- Profan Garden High Pro Tt 125mm 5 Inch Turbo Extractor (introduces air into the tent)
- Grip Clip Fan 6 Inch Oscillating
- 6" Carbon Filter
Lighting
Homemade panel of 15 Baw 50w LED lights (750w Total)
Nutrients
The entire BioProyect line
Day 0
I soaked the 4 Bio Proyect rockwool cubes in a bucket with a pH of 4.49 (I used pH down solution)
Day 1
We filled the RDWC 4.1 system to the indicated height, 80 liters in total, then we injected the HIDRO VEGE, HIDRO MICRO, and HIDRO MACRO nutrients with syringes. We also added to the solution the BIOBACTER line: Mycorrhizae, Trichoderma, and Azospirillum.
We followed the hydroponic growing chart from BioProyect, but we preferred to use a little less than indicated, so we can adjust the EC (electrical conductivity) if necessary.
Once the EC is established, we can control the pH; in our case, we need to lower it to 5.5 with the BioPH- solution.
Keep in mind that each process takes time until all solutions mix well to obtain stable EC and pH values.
Once the system is circulating with all the indicated parameters, we move on to handle the rockwool and the seeds.
We drained the rockwool cubes to remove excess water and used a skewer to pierce the rockwool completely, then we placed the seeds so that the tip is facing down and at a depth twice the height of the seed. We put the rockwool cubes in the baskets and wait for the girls to sprout.
Since this is my first hydroponic grow, I used bulk autoflowering seeds of "Ojitos Rojos": 3 White Widow and 1 Fruite Cake.

David_Clark All the girls were born, I'm having humidity problems since it's low and not at the ideal values for this stage (65-70%). I'm going to put a humidifier and wait for more results.

David_Clark This week I didn't take any photos, they're doing well. I was able to solve a fungus issue in the roots with hypochlorous acid.

David_Clark This week I did some defoliation and topped at the 5th and 6th node. I also put clips on to do LST on the plants and start covering the whole net.

David_Clark I did defoliation again on 3 out of the 4, left 1 to see the difference in lateral growth, and I added more clips to train the plant. I had to add 5 liters of water since they are starting to eat quite a bit.
