No problem germinating my Power Skunk and Ice freebies. Doesn't matter at all how small the seeds are, they germinated and grew just as well as anything. They were well fed and got tons of light, I did my best to make this work.
There are better choices for indica and sativa. They get you high, but then a lot of weed does. The Ice mentioned earlier looks pure indica and has neat leaves and growth habit in veg. Flowering was a huge disappointment. These were slow to bud, and even though they eventually bud like indicas and have calyxes longer than usual, the leafy buds are very airy so far and don't seem to be filling out. Worst indica buds ever. Very late to produce any frosting, and it's barely visible, even though it's been dank for a long time. This seemed overly sensitive to being too close to the (air cooled) light, got a lot of weird burning where other strains didn't mind. Smells just like all the commercial weed in town.
Power Skunk looks pure sativa. Very branchy and tall. Very. Vigorous but not in that good a way. Pretty leafy considering how thin the leaves are and how far apart the nodes are. There was some variation in the plants, some even more sativa than others; those have completely worthless, unbelievably airy and runny buds. The best were merely pretty runny and airy. Runny and airy is also a good description for it in veg. There will be some yield for the better plants, but it will be leafy and stemmy, nothing that resembles real buds. Very light and odd odor. Citrusy I guess but not like any citrus. Late frosting, not a lot of it, not sticky at all, the "buds" have a "dryness" about them. This was sensitive to being rootbound and needed a lot of room both above and below ground. It will all be turned into oil, along with the Ice.
