Hello people. I am starting my first grow, hydroponic drip system in rockwool.
I have bought tent 80x80cm, ventilation, lights (Lumatec Attic 200W), Rasperry Pi 4 with Homeseer and Z-wave plugs (for remote control).
I started germinating one seed 5 days ago, and the other 4 days ago. I followed the recipe for Canna Aqua “Start rooting/seedling” mixture and measured the PH to 5,8. (I didnt calibrate my meter, but I confirmed the PH with a test kit which arrived today). I decided to put them in the tent, under the light at 20%. However, I did have a good 1,2m between the light and the plant. After some research, I’m not sure this is enough.
Now they look like this:
The one on the left is a White Widow (5 days old), the one on the right is an AK47, (4 days old). The AK looks very unhealthy, which I think can be because of:
-Low light for 3-4 days (I adjusted the light to 40cm today, at 40%)
-Low air humidity for 3-4 days. I had a humidifier, but I think the auto setting is broken.
-Too much water. I soaked the cubes before seeding them, AND watered both after 2 days…
The grow light manual says that a plant should receive 289-466 umol/s/m2 at 40cm. I suppose I can multiply that by 0,4 when i set the lamp at 40%? Is this OK for this phase?
Is there any hope for my AK47?
