While I haven't grown Iron before I trialed a very similar series this year and loved it. After trying Iron I've heard a couple growers say that's all they're using from now on. I'm excited to try myself!
It has straight hard stems and the tips don't stretch after cutting. They are a touch shorter than some cut strains, which can be countered by offering extra water. We often have 3' stock on our farm, so a couple inches shorter is fine by me!
This refined series is available in a full range of colors. Expect 55% doubles.
Grown in a 128 tray, billed as a 125. Plugs are double sown and should be planted that way. Stock likes it crowed. 8-12 plants per square foot.
Order 6 or more weeks in advance of desired ship date.
