Athosanswered grow question 6 years ago If you can increase the temperature above 23°C (73°F), the growth rate will be much better. Second, be sure not to be over watering, which is a very usual mistake than makes the growth slows down to a crawl; a cup of water should last you 5 to 7 days, before watering again at this stage. Third, try putting the seedling closer to the light. Fourth, related to watering, next time start in solo cups, since you started in 7 liter pots, you most likely are giving it too much water.
