My pots are 3-3/4 in. Removed a good layer of pellets so the seedling would be a bit lower and closer to pellets washed from the sprinklers. I use a low pressure sprinkler system. For this first week I only use plain water on a cycle of 5min On/10min Off. Lights are set at 25% and gradually increased to 50% by the end of the week.
Looking good, the stretch from flowering is exciting. With the light penetration you mentioned, should see some decent sized buds on that poison berry. My first run of it was outdoor during winter, just 1 plant. Genetics are nice but mine yielded low for obvious reasons. My recent germ didnt take so I have my last two soaking now. I’m excited to see your harvest, keep it up
