hi there. I am having trouble finding a cheap(er) source for d-limonene. I am using this tek to extract with. In it it says to do at least three d-limonene soaks (step 2). The problem is, I have 1700g of cactus powder to extract (extracting in 200-300g increments once I finish a practice run). Does anyone have a link to the cheapest d-limonene they know of? I found some ebay and amazon sellers but I seek the cheapest price tag ever. Is there yet an alternative to d-limonene that is cheaper and not-toxic? This is probably the most expensive extraction I have ever done lol.

You should consider using other techniques, such as the one depicted here: http://www.thenook.org/archives/tek/cactusex.htm

already did. I narrowed it down to 69ron as the one i want to use.

If you want to use a cheap alternative to limonene, you can use sunflower oil instead. There is a tek for it too

thanks kermit. the limonene that was already put to use will be finished before going further.

can i re-use the d-limonene at least once? my thought is that there would be lots of trash in it but is it worth it to try?

limo can be reused repetitively, some people have used a gallon for a years worth of extractions just fine. clean your nps and filter it, should be just fine for what youre trying
