First Ever

Worried they aren't growing enough, upped the intensity of light on Saturday 2/12 as I originally only had about 4-5000lux. Upped that to 25,000lux on my HLG board. I technically need to water these 0.55L per day but that's too much water I think. It's living soil though so I'm waiting every other day at least to water. Very eager for 3-5days from now to confirm the plants are all doing OK (I'm worried I'm seeing some stretching and thin stems).
