Glad to hear others running with no storage. For the added cost I could buy enough log length wood to heat my house for about 6 years or more. Poplar as us easteners call it is aspen as some have indicated. There is two types- trembling or quaking aspen and big tooth aspen and both have same wood properties. That is one reason I bought a gassifier so I can burn what I have on my woodlot - hemlock, red spruce and pine. Cut it, dry it, burn it and turn the stat up. The smoke from aspen burning in a regular woodstove really reaks though not sure why.
