India_Calcoen I planted my seed on the 25th of April in a Romberg BoQube propagator with LED-lighting and a heat mat. I used Romberg coir substrate (coconut) and biodegradable pots. The temperature varies between 22-30 degrees.

India_Calcoen My seedlings are stretching to the light. The Romberg LED lighting does not provide enough light. The LED strip provides 1300 lux and I read on the RQS website: “Cannabis seedlings like to receive around 16 hours of light per day at an intensity of 375 lumens and 4000 lux.”

Replanted the plants in larger biodegradable pots, added potting soil and placed them on a windowsill facing the south.

I forgot to measure my plants last week, but it seems they have gained some leaves and some height! I’m waiting for the weather to be warmer to put them outside.

I put the plants in the garden, between some basil and Tagetes. Three weeks ago I added green Culterra (N10-P4-K6) to my soil. I hope the soil absorbed it and my plants can benefit from it. Today I added some potting soil in the hole I dug.

Black Runtz is doing fine. I didn’t have to water her, because it rained this week. She grew a few centimetres. Nothing special.
