Hey all…I’m a bit concerned about my outdoor grow! I live in the GTA (Greater Toronto Area) and the girl has been outside since May 24. Planet of the Grapes by Ethos, 9 week flower time. The weather has been rainy and chilly with only a handful of warmer days (above 70 degrees). My main question is, do Grow Dots only release ferts above 70 degrees or also via watering? I use Recharge 2 times per week at full dose. Recharge is amazing! If the ferts only release during warm temps, I may have a problem! Our growing season is finished by the end of September, sometimes the beginning of October till the first frost hits. If the bloom ferts kick in later due to shitty weather, the girl won’t have enough time to fill out and finish before the first frost. Should I add something in mid to late September to force it to finish? Am I totally over thinking this? I appreciate the help provided by this awesome community…happy growing!
Grow dots release nutrients based upon temperature but are activated by water. I believe they are designed to release best between 75-85 degrees if I remember correctly. The main thing to remember about the dots is how much veg time (4 weeks) they provide before the nutes switch to flower ratio for 10-12 weeks. Outside flowering starts around the end of the first week of august so I would make sure I at least do a final top dress around the 2nd week of July so you have appropriate nutes for transition to flower. You may need another top dress in between now and then as well depending on when you first added the dots.
Thank you Dr. Phil Goude for your reply. Today is the 4 week mark since starting the dots. The weather during this month has been crappy! It is improving and I’ve definately noticed a lot of new growth. So if I understand correctly, this is the time to start amending being that we still have 5 weeks left until bloom starts. Should I add more dots or perhaps synthetic nutes till flower? Same question for when it’s in flower. I was really hoping to avoid having to use synthetics! Thanks for your help, it’s much appreciated.
