Spider Mite

My plants have spider mite...AGAIN... * sigh *. I lost some plants to mite a while back so I've been keeping an eye on it and luckily I think I've caught it early. I've been reading an earlier thread in here about it, and made a note of apparent cures, and I have a couple of questions. Firstly, with the white oil and neem oil, where do I buy them and do they need to be diluted, and if so to what ratio. I read that lemon juice will kill the mite, and growing garlic in with the plants will act as a deterrent, I prefer to use the least chemicals the better, so are these two suggestions likely to be good? I've also been told ( not here) to use either a flea/pest bom…

These babies have been in the blue-light vegetation room for about 2-4 months and recently was attacked by (I had thought) a large insect. This insect made it's home on the up until then healty plants. I thought it might have been a good guy so I left it there as I do with lady bugs and spiders. After about a week I noticed some of the leaves of the plant it was on curling, forming inverse half tubes out of the sickly leaves. A quick spray of pyrithum and the bug was dead. Anti-joy and the poblem's continue having spread to half the room in two weeks. I have used Bio-Bugs for over a year and have had no insect problems at all so I'm at loss to what this is caused by. Here…

I'm running a hydro setup indoors in soil. I got home from uni today and found some bubbly yellow growths coming out of the soil. Sort of looks like parmessan cheese. Anyone know what these are? are they bad? how to kill? etc

I bought an insect spray from woolies in the hope that it would rid my plants of the little green caterpillers i had been getting. I sprayed em last night, and today when I just checked em, the leaves are turning brown and drying out. It is a fucking hot day here today, but I would think that has fuck all to do with it. I have moved the pots into the laundry, out of the sun, and washed the plant down with fresh water. some of the leaves were so dry the just crackled in my hands. man i shoulda just gone to the garden centre and got some neem or biocide. I am a fucking retard! anyone had any experience with shit like this. the active ingredients in the spray were Pyrethr…

Greetings. I have just noticed these little tiny caterpillars (about 3mm long) on the underside of my leaves. They appear to be making bits of the leaves go transparent/clear... See attached pic of what these little suckers look like. Any, preferably chemical free, ideas to get rid of them will be appreciated.

I have a few plants growing in pots outside. they are all about two weeks old and growing pretty strong. Yesterday when I check them, some of the leaves had a clear part on them ( sorry , best description I can think of) after checking under the leaves ( thanks WC) I found some little green caterpillers. I squashed all the ones I could find, but want a more permanent solution to this problem. I read in a previous post that someone had used a spray product called "NEEM". Can any one offer some advice on this situation many thanks

I presume that most people will disagree with me here but stiff. I soaked my seeds overnight in distilled water and when they started to crack, I put them into 1" growool cubes as thousands of growers do. When they got to around 2" tall I transferred them to the grow room. I planted them in expanded clay and had the watering system on for 15 mins and off for 2 hours. Result, half dead seedlings. After posting some pics on here, I was told it looked like they could have root rot. I thought "rot", couldnt be. I was using Phytoff and Oxy Plus. Well, lets cut it short. They were right. Those stinking, useless, seed killing rockwell cubes were at fault. I was told th…

i got this seedling about 2 weeks old out in the bush. its got 3 sets of leaves, neway one of the rounded leaves (the first ones) has a big chunk taken out of it. im just wondering what kinda animals/insects are in the bush (north brisbane) and is there much chance of them damaging/killing ur plants. anyone here lost crops to animals or insects outdoors? someone told me that insects are nutralised outdoors by other insects and small animals, thats why ppl have big problems indoors. (probably very wrong though)
