well the diatomacious earth is very... light... spreads like dust... and a little goes a long way. If you are gonna use CO2, then you just wanna flood the whole unit, no exhaust.
Careful with CO2, plants become addicted.
If your levels suddenly drop, the plants will just stop.
Wish it was that ez. Covered my pots with 1/2 cup DE each... Using yellow sticky traps...and BTI in all rez's... I can't fuckin win, driving me crazy. There aren't many, but they aren't gone that's for sure.
For everyone battling fungus gnats i too had the battle which lasted several weeks until i tried the one solution i was avoiding for some strange reason, which is covering the topsoil with sand........it works like a charm and i havent seen a fungus gnat in almost 6 weeks now
Had a long chat with someone a little more experienced than me, ran all my ideas past him and he advised me to use a combination of sticky traps and "gnat off", and that anything else probably wasn't worth doing. So thats what i've decided to do! I'm also going to substitute my canna flowering feed for something called "Ripen", used it last grow with good results.
"Ripen is a superb late bloom feed that has the perfect nutrient formulation for the end of flowering/fruiting. Due to its unique composition, Ripen accelerates the final stage of flowering to provide a fantastic finish to your fruits and flowers before flushing. It can also be used to speed up the flowering process for an early finish - which proves very useful if you're struggling from a mite infestation or pest problem. A complete replacement for your normal bloom nutrient, Ripen is a pure flowering feed which we highly recommend in all growing media. Use at 4-5mls per Litre for 2 weeks maximum prior to desired harvesting date"
How long i actually flower this plant for before chopping will be decided in the next week. It all depends how effectively i can rid my plant of this gnat problem. If i can't get rid of it and only keep it at bay, i'm gona be forced to harvest her maybe at the end of week 9. If i can get rid of pretty much everything, ideally i'd like to harvest her at the end of week 11, bang in the middle of the 10-12 week suggested flowering time. That would mean 5 more weeks of growth... i cannot even begin to imagine how she's not gona suffer a huge mould outbreak if i let her go that long, her buds are HUGE already! Concentrating whole branches worth of growth into the top 6-9 inches works WONDERS, along with something else i've done this week but i'll include that in tomorrows update.
Anyway, appreciate all the advice and suggestions big time, thanks u lot. Fungus gnats are without a doubt the longest issue i've come across in my growing career so far, preventative measures are gona be taken without fail every grow from now on...
Check these sticky traps, 24hrs after being placed in my cab. I've got like 2 and a half packs hung around my cab, will replace them once a week unless they literally get completely covered in flies..
So yeh one more week of Canna nutes + Gnat off, then i might switch to ripen, time will tell. Will use ripen for 2 weeks, then maybe a week of flushing with water to suck all nutes out of the leaves ect.
