Things are improving since switching away from cheap PH pens. The one female in flower has thick main stems. The other smaller side-branches are slowly catching up. The other plants are more even, though one ended up as a male and the other is in veg still.

This is a tester pack.
"Description: Shockwave is a cross between Shark Shock and our Alien Rift male. Most phenotypes exhibit floral berry odors with a hint of your old sweaty gym bag. Vigorous vertical growth if left un-topped; low-stress training techniques are encouraged to supplement yields. Flowers will reach maturity from 7 – 8.5 weeks, with most phenotypes finishing after 55 days. Expect greasy, frosty flowers – this is an ideal strain for extract artists and flower-lovers alike."
