20/01/2025 Seedlings have definitely grown in size! Bottom watered again today. Mixed 3L solution of Calmag, Growell Plus 8:8:8, Seaweed extract (2ml / 1ml / 1ml) and watered 1L per pot. Solution was sucked dry from tray relatively fast, guess the roots are growing. 21/01/2025 Measured PPFD / DLI today and found that my existing light had a relatively low ppfd value output. Reading 50 plus PPFD / 4.5 DLI at 24 inch height 75% power, generating insane amounts of heat if the grow tent is closed. Thing is the max ppfd is about 150 at 24 inches. Can't bring down the lights more without potentially causing light burn due to the high DLI low ppfd ratio. Fortunately I have the tent in a temperature controlled room so I had to leave the tent open to ensure there was good airflow cooling down the excess heat without causing too much of a temp shift. Managed to bring up the humidity by adding a larger humidifier maintaining 60 to 70 % range. Did myself a favour and ordered the vivosun aerolight a200se to go along with the rest of the vivosun kit. Hoping it arrives by week 3! Besides this, seedlings look healthy, did some foliar feeding with homemade wood vinegar (5ml to 1L) after lights out. 22/01/2025 I almost killed my plants with light lol. Turns out my existing light was putting up alright dishing out 1200 pfd from 24 inches at max. I noticed some skewed reading when I was tilting my phone screen so decided to take off the screen protector and damn.. ppfd was at 800 ppfd! It was the screen protector not the lights 😆 Since there were no signs of yellowing or wilting I decided to keep it at 400 ppfd. Bottom watered with 1L each of (2ml CalMag / 1ml Growell Plus 8:8:8 / 1ml Seaweed to 3L phed to 5.9) had about 100 ml excess after waiting for 10 mins so I drained out the excess. 23/01/2025 Fortunately my blunder with the lights didn't cost me too much. Plants still looking healthy, 3rd set of true leaves opening up.
