House and Garden / Coco question
- Thread starter AloeRuss
- Start date
I'm not going to read the whole thread. BUT, when H&G switched thier Roots Ex formulation I continued to do what I had done before, mixing in the order prescribed by H&G, but pHing after the Roots ex. Things went south FAST!!! root rot, fungus gnats and a general decline in health and quality of my grow. When I finally switched, pHed then added the Roots Ex (ignoring the plunge in pH) everything went back to healthy and beautiful (after a short battle with the fucking gnats).
I guess in this case, read and follow the instructions

SM90 works for me.
It might not wipe out an existing population, but it seems like they look for greener pastures when you use that stuff
Dont think you would want to continue roots excel with something like sm90, but then again I dont think RE is worth the price
yellow cards are only meant to determine pressure (the extent of the population).
For organic control anything with rosemary essential oil is probably the best. Other essentials like thyme are great as long as it has rosemary in it. SNS makes a product but it's pricey (243 or 203). predatory nematodes are good too as is neem oil.
If they're in early veg u may want to try imidicloprid if you want to use chemiclas, just not in flower.
oh yeah, top dress with sand or gnatnix to make it hard for the adult to lay eggs.
BTW - bayer complete is imidicloprid...
does ogbiowar have bti?
Gnatrol has bti as well, which if you can find works well. I found mosquito dunks don't work for me tho...
I just wiped out my gnats with a combo of gnatrol and sticky gnat-stix in the pots. It took about 2 weeks and 3 applications to do get all the larve. The stix get the adults. I'll use the gnatrol for a few more waterings, just to be safe. You can find gnatrol on e-bay in all sorts of quantities. I use 1tsp/gal with excellent results. FWIW, I've had good results with predator nematodes too, but gnatrol is way cheaper and OMRI approved.
Good to know. Just bought gnatnix so i'm glad to hear that since it fucking 15 bucks for a little bag!
Gnatnix is a SCAM!!! 5oz of gnatrol was $16...delivered off ebay. 5 oz will treat more than 100gal water. You can get 1lb for ~$40 if you have a BIG garden. You don't need to water all the way through with gnatrol, just wet the top few inches of medium, that's where the larva all are anyway. I'm treating 2gal bags with ~16oz of solution per treatment, per plant. At that rate, 5oz is enough to treat 800 2gal bags. I have considerably less, how abot you?
I'm in pro-mix and only water every few days, but in coco I guess you could do the treatment after you watered each day if price is a concern. What I'm getting at is you'd probably wash all the gnatrol out of the coco unless you added it every time after you watered, or added it to your entire mix, which is pretty wasteful.
I checked my notes: I'm actually using 1/2 tsp gnatrol/gal of water. A little goes a long way. Like most infestations, all it requires is multiple apps of the correct treatment. You should see results in 3-4 days, and victory at around 2 weeks. Keep a few sticky traps around to monitor the situation.
My friend garden - thousands of larvae would be flushing out with runoff.
It was frigging crazy how it looked.
Half a teaspoon per gallon and do 3-4 times consistently in a raw?
It look so nasty when mixed, I always think it harms my plants
I use 1/2 tsp/gal, maybe 1tsp/gal if they're really bad. There is no need to add the gnatrol solution until runoff. Just enough to penetrate the first few inches of your coco should be enough. A 5gal bucket should be enough to treat 20-40 plants depending on the size of the container. Maybe 50 for you, since you're probably using <2gal pots with coco.
I haven't seen any gnats since the 3rd application, but I'm going for a few more apps before I let up. I've got a few traps out to keep an eye on things.
The gnatrol does make the water look funky, but so does kelp or guano. Gnatrol is OMRI listed, give it a chance, and I think you'll be happy with it. Somebody else suggested essential oils, which do work, but that shit STINKS!
Does the gnatrol say if it's good when using nematodes, i mean it won't kill my predatory nematodes? I am assuming the bti only affect insects not nematodes?
I did a quick search, but no definitive answer. My guess is yes, the gnatrol will kill the nematodes, but killing the gnats will kill the nematodes too(no more food). I'd put my trust in the gnatrol, and put the nematode money in the bank. Todes work fine, but they cost too much, and take too long to work.
I did some extensive search on SM90 because I was told by senior people it does kill anything live in the soil.
It seems that it does. So I put my plants on regular SM90 2ml a gallon splash.
Now, coconutz was right. SM90 with its lethal features to anything living will overwrite Gnatral, so I had to decide which one to go with. But since SM90 has other benefits for your roots, I decided to go with sm90

I dont know that it will kill everything living.
In fact Ive said Im not sure that it will wipe out an existing population of anything...
Their recommendations are 2-3ml.
You should probably go with the higher end with an existing problem. Lower for routine maintenance.
DHF recommends using it at 5ml per gallon. You might wanna hit them with a high dose a few times since it doesnt seem to hurt the plants at 5ml...

How much are you using HP?And do you give more through out veg or do you just do your pretreatment in the beginning and your good to go??
I use the same stuff at 5 mil per gal h2o.Have not pre treated my coco but i make sure the girls get a dose while still vegging.
