I’ve seen a lot of stupid organic recipes posted by others over the years that are either ineffective, cause foliage damage, or a combination of the two.
I had a 12’x16’ flower room and three 5’x5’x6’ nursery tents that I ran for about 2 years - until I got the borg. I spent over $800 on pesticides that included forbid, azagaurd, avid, spinosad, venerate (absolute snake oil), burning sulfur, and a multitude of others that didn’t work. Forbid had the plants perk up for 1 day then they were back to dying.
The borg decimated everything I had. I lost 2 flower cycles in a row with an expected harvest of 5# or so each cycle. I lost all of my clones, vegging plants, and mothers. It was the single most devastating event of my life.
I shut down for 8 months. Sanitized everything with 10% bleach. I got the borg again. There must have been dormant eggs somewhere that took hold of my seedlings around week 3 or 4. I couldn’t believe I was seeing the eggs and damage again on the bottom of my leaves. I just about trashed everything 2 weeks ago so I figured I’d try something I was pretty sure would kill the plant, but I really had nothing to lose.
91% isopropyl alcohol. Do not use rubbing alcohol. It contains additives that will damage the plants. For heavy infestations 30% iso / 70% water. Use a spray bottle for small plants. Use a pump sprayer for large plants.
- Mix your iso with water in the appropriate amounts. Heavy infestation: 30% 91% isopropyl alcohol = 9.6oz iso and 22.4 oz water for a 32 oz bottle. Spray once every 3-4 days. A maintenance spray is 20% 91% isopropyl alcohol to 80% water. Use a calculator. It’s simple math but math you do not want to make a mistake with. 30% will cause superficial leaf damage and if that is a concern use 20% and you will see no damage to any leaves while decimating the borg.
I was terrified that I was going to lose my ladies so I went 30% for 3 applications. After that I couldn’t find a single egg on any plant. 30% is only for heavy infestations and is only to be used for 1-2 applications. 20% will not cause leaf damage at all while still being highly effective.
-
Make sure your plants are watered properly. If you spray dehydrated plants you will kill them.
-
Spray heavily either at lights off or you can spray during your lights on cycle but you must not leave the plants under any intense lighting. I remove them from my tent, spray them, then I leave them under a 26w florescent light until the next day allowing them to dry completely. Obviously if you’re flowering moving plants in and out isn’t a good idea, so spraying at lights off in the flower cycle is the best course of action.
Notes) If you’re spraying small plants logic implies you should mix a lower concentration. 20% has caused zero damage to any foliage at all whatsoever.
I always hate when people post their home pesticide recipes without showing any pictures of their plants. Half the time these yokals will readily admit they’ve never used the recipe they posted on their own plants. WTF? Really?
This is my biggest wedding cake lady which I was about to trash 2 weeks ago. These are the results of using the recipe I’ve written. I’ll post pictures of the other 3 at lights on. My big one spent the night outside of the tent because I forgot to water it before I left for work. By the time I got home she was wilted and ugly looking. I figured I’d give her the night to recover. And this is how she looks this morning:
