No
Needs an active growing climate with the highest possible light levels. Optimum is more than 15 mol per m² per day. Can grow in lower light levels, but increases crop time (see lead time per season). Do not start crop too early in cold nights and lower light levels, which will cause a delay. Best grown outside. Finish lead times for Northwest Europe: add 2 to 3 weeks to indicated lead times. Allow media to dry in between waterings. Avoid growing wet. Monitor EC in pot during active growth to avoid leaf yellowing (chlorosis). Gallon is the main size; recommend 3 ppp, planted in a triangle, for superior finished quality (compared to vegetative with 1 plant per pot). If plugs are not pinched, pinch 2 to 3 weeks after transplant, above 4 to 5 leaf node pairs. NOTE: Pinch not needed for larger (2 gallon and up) containers. Instead, use higher daminozide concentration of 5,000 ppm for 1 to 2 applications in the first 2 to 3 weeks after transplant. Needs an active growing climate with the highest possible light levels. Optimum is more than 15 mol per m² per day. Can grow in lower light levels, but that will increase crop time. Do not start too early in cold nights and lower light levels, which will cause delay. Allow media to dry between watering; avoid growing wet. Monitor EC in pot during active growth to avoid leaf yellowing. One gallon is the perfect size; use 1 multi-seed plug (3 to 4 seeds) or 3 x 288 plug, and no pinch or PGRs needed. For quarts, use a smaller plug size (288) and 1 seed/cell; pinching is optional (leave 3 to 4 leaf nodes), same for PGR spray (1,500 ppm daminozide). Pinching will delay 1 to 2 weeks. Will finish reliably as a first-year-flowering perennial if not sown later than Week 16. No need for short-day treatment of plugs (like Goldsturm does). For PGRs, use daminozide 3x 5,000 ppm spray as an option for more controlled growth. Daminozide/chlormequat chloride tank mix (3x daminozide 2,500 ppm/chlormequat chloride 750 ppm spray) could be an optional treatment. Using uniconazole-P or paclobutrazol spray is not recommended, as they made the foliage smaller and the plants looked spindly. This is a relatively high feeder, so prevent Mg, Ca and Fe deficiencies. High light and good ventilation are beneficial. Possible foliage issues can occur on new growth leaves (puckering, cup up, tip marginal burning) during flower induction period because of more difficult mineral transport during this developmental stage. There is no good fertilisation correction possible, only maintain as low an RH as possible with optimal ventilation to have optimal plant transport of elements. The foliage issue will mostly have disappeared at flowering sales stage. For Spring and Autumn forcing: See Perennial Forcing Guide.
