Kannabia/Ace Seeds/ Ripper Seeds

5/12/2023 (Day 42): Cool and not cool in the 4x4: 10th day of 12/12. The plants all look very good, happy and healthy but... something ( I think the driver) doesn't work ok anymore with my SE 5000. I noticed a drop in the max ¨PAR in the middle of last grow but thought my led bars had to be cleaned. The cleaning changed nothing and the panel kept on losing efficiency since I started this grow ( 4th one with this panel): At 100%, 22 cm above the canopy max PAR is at 40% of what it should be and has been for.. yes ! 3 long grows. I ordered another one and start the process to test Spider Farmer support regarding the repairs on the faulty model still under warranty. For now the plants doesn't seem to matter but I 'don't see tons of pistils after 10 days of 12/12. In the 3X3: Well.. They all look good, happy and healthy too :) And the SF 4000 (8th grow) performs just like for the 1st grow: Perfectly. Considering that the SE5000 also did a great job (even better) as long as it worked correctly, this is the reason why I chose Spider Farmer again to replace... Spider Farmer !. I'll stay happy if activating the warranty to have the sick panel fixed/repaired doesn't turn in to a nightmare. I switched to 12/12 last sunday: 3rd day of flowering.
