WeedSeedEx. Permanent Marker / Biotabs

kohlrabi Sprouted on day 5! I timed it so that the first week could begin at the weekend, and luckily the plan worked out. I can only recommend giving it a try – with this method, I have found a so far 100% reliable germination method: Soak the seed for 12-24 hours in approx. 50 ml of distilled water with a few drops of humic acid, then place the still-closed seed in a Root Riot cube and stick it directly into the finished pot with soil. All you need to do then is water it a little every morning and in 4-6 days the plant will pop its head out of the soil. Substrate One thing I'm not doing quite according to Biotabs' plan is the substrate. I have so much recycled soil (using bokashi/earthworms) that I didn't want to buy new substrate. I supplemented this with coco and pumice. Since this way the soil already contains nutrients, I'm using one less Biotab than recommended. I'm keeping an eye on the colour of the leaves and adjust if necessary. My biggest concern is that the soil might be too nutrient-rich for the germination and cultivation phase. We'll see. More on the irrigation setup coming next week!
