<span class="link_user">@JBOrganix</span>, I just added one as well. After planting 5 seeds directly in soil and watching nothing happen for a week I purchased a heater suspecting was too cold. 3 days later and 10 days from planting and 2 little babies sprouted this morning. Highly recommend a small, cheap heater.
<span class="link_user">@blendmedmedman</span>, made the oil with food grade alcohol. If you are looking for a how to just search on YouTube for Canolator it’s in Dutch :-).
The oil is for medical use. I just take some drops.
