Should I spray tonight or wait till morning. Daytime temps are just below 80 with morning temps around 55 and low humidity. Just got my BT in the mail and anxious to get spraying but idk if 55 is too cold to be wet or if the morning dew will make it less effective then drying in the morning sun. Thanks

Also it doesn't say to add dish soap like neem oil does.. Should I add it anyways at the same rate?
Tonight would be better for the spray as uv light can interfere with it IIRC. I'd say no dish soap since it's a bacteria.

I always spray my plants in the morning, before the sunlight hits them. You never want to spray plants in the evening once buds are forming. The general rule says "never put your plants to bed wet."

I always add a few drops of Dr. Bronner's Magic Soap, which acts as a "sticker-spreader."

I've heard the general rule as "dawn or dusk", but to each their own. Do the instructions have any cautions?

Well, you can spray your plants at dusk if you want, but I said that it's not a good idea during flowering.

I don't know what instructions you're talking about, but if you want some more wisdom about spraying, I'll tell you another general rule. The rule of 140 says that if the air temperature added to the relative humidity is more that 140 then don't spray.

The instructions I referred to were for the BT product @SuperNutz bought. Specifically I was wondering if the instructions indicated the best time of day for the spray to be applied.

I've had those over 140 nights lately, starting to see a bottom leaf here and there with some sort of white mildew or something, not from spraying though, that night was not humid and the next day was dry but past two nights humidity has been in the 90's.

I'm growing three different strains outdoors. One of my strains caught a little case of powdery mildew in June, early in veg. Impacted only the lower leaves but started moving up the plant. I caught it early and used a common fungicide from Home Depot. I diluted it a little bit and sprayed all my plants. It worked beautifully. I did end up removing most of the impacted leaves before I sprayed.

Just a suggestion, if your seeing any kind of white / grayish mildew, that's something you want to jump on asap. If left unchecked it will spread and can destroy the whole plant.

Let us know how it turns out.

I'm a big fan of spraying BT at night. I soak em down real good. I've observed bud worms and they will generally come out at dawn to feed. They can't take direct, hot sun for very long. Once they have breakfast they tend to retreat towards the stems, or back into your flowers. Late at night or crack ass of dawn.

Please report back on how this turned out.

Gonna have to wait till tomorrow night for good conditions to spray again, unfortunately I have to do a round of neem before the BT because I found a few leaves on one of my girls with spider mites while trimming out the little stuff in the middle, Grrr… I'll post back in about a week as far as cannapillars and these mites go.

Outdoors is a constant battle.

Just got it from my gentle BT spraying. Love being out there in the dark, hearing the summer bugs, as I spray my properly diluted BT.

Soaked them ladies down. Flower tops are just starting to form on my feminized. Be a little longer on the reg Bodhi.

It's been four or five days since the last treatment.

The beauty of BT is you don't need a lot. Four teaspoons to a gallon.

I wasn't able to spray tonight, hope tomorrow the winds die down earlier. Was still 15 mph winds when I gave up waiting and went to the grocery store at 9 pm. The thing about wind here is it changes direction second to second lol. Was cutting low branches on the tomato plants this afternoon and every time I threw them out of the garden they came flying right back to me lol.

I couldn't quite determine how big that bud worm was. A week or two ago I found a little brown caterpillar thing in one of my girls, and I picked it off. Now I'm noticing that I have what locals call "meat bees" picking through my plants, and I'm wondering if they're finding and eating more of these little things I found. It was between 1/4"-18" long.

What's the BT, or the bacteria that are in it?

Are the GrowFAQs back up yet?
What region is this? I have not seen the worms here in the PNW.....YET!

Got them good and soaked with neem at dusk. How long you think I should wait to hit them with the BT again?
