Neem Oil will take care of fungus gnats as well. Put a small bowl in the grobo and they’re gone.
Thank you, I may do that as well. I wouldn’t have to spray the coco pod?
Nope. It will attract the fungus gnats and then kill them.
I ordered some neem oil and some mosquito bites which has Bacillus Thuringiensis Subspecies Isrealensis which should kill the larvae as well. So far I don’t seem them anymore on the coco pod, but just want to be sure they’re gone.
I keep seeing some of my leaves with rust colored spots that slowly take over the whole leaf. This is mostly happening on the lowest leaves.
From behind the leaf there’s these weird blotches:
It’s hard to see, but near the stem are some of these spots from the front:
Could this be disease or nutrient deficiency?
I treated the coco pod with a mixture of neem oil/water/BTI. So far so good.
The more I read into the brown spots on my plant the more I think it’s a calcium deficiency. I’ve added 10ml of cal-mag to see if it improves over time. Is it recommended to use Cal-mag with a Grobo grow?
My first grow too. what’s your idea water temp and temperature for when the lights on in the day time?
Hey there the ideal water temperature is around 68-72 degrees Fahrenheit. It can be hard for me to keep that temperature so in order to avoid root rot I just supplement each watering with Hydroguard and my roots look great!
I’ve been monitoring the coco pod since using the BTI/neem oil water mix and it does seem to have done the trick. I haven’t seen any larvae for a couple days.
Good to hear!
Rule of thumb I always go by is go by is to only open the unit when I am in clean clothes! keeps pests from transferring off me or my pet who routinely comes to me!
Thank you, Todd! That’s a good rule. I also think that maybe this gnat came in the fan holes because they weren’t turned on. Support assisted with this yesterday and I hope it will also help keep those little guys away.
All fans dont operate all the time. The lower fans come on in different stages! 0
Yes, but I was almost to transition phase (day 39) and the fans hadn’t come on yet. Stacey helped me by telling me to upgrade the firmware and then she said she adjusted the fans schedule in the recipe somehow. Now they’re running great!
Awesome to hear! Now you know for next grow. Sounds like a ted talk topic no one told you about
Haha, indeed! The world need more weed Ted Talks.
