Cubes are probably the easiest to grow, and while they don't have the potency of wood-lovers (usually) that is fine with me, because I like to know that I can set the dose fairly accurately. Wood lovers can be so strong as to make it difficult to get a good dose setting - too easy to go much stronger than intended. That combined with the very long grow times, etc. make wood lovers more of a curiosity for me. I can add or subtract grams in a tea with cubes and know that I can handle the minor potency differences. For micro dosing this is REALLY important as half a gram of cube might be 0.05 gram of woody.
Using one of the many oat or popcorn teks and just plain Coir can get you what you want. Using bleach. ISO-alcohol, and H202 and good clean technique and you can have yourself some sacraments in a matter of a few weeks.
