Hey Guys, I've just started my first outdoor grow and I'm about three weeks in. I woke up this morning to find somethings had a wee munch on one of my plants. I've uploaded a before and after photo. I'm guessing its some moth or caterpillar but not to sure. If anyones got any ideas on what it could be and how to stop whatever it is helping themselves that would be awesome. P.s I saw some Yates anti bug spray at the supermarket a while ago but not sure if it will damage the plant or not? Cheers,

I was bored and started to look for something to do. I found Eco Pest-Oil outside, so I went on and tried out this product. This afternoon, I sprayed my Tomato plants and some flowers with it because there are 30-50 of them little Sciarid fly or Fungus gnats and some white eggs down the tomato leafs. I found out they are dead on the ground after 1-2 hours. Very nice product and also can be used on Cannabis plants and many different pests.

Hey team So I got all setup with a familiar system I've done before. DWC in black buckets, single part nutes, PH lowered, air-stones. (Although PH testing is new to me.) Just seedlings barely out of small rock wool cubes. Made up fresh juice yesterday and it was stable @ EC 1.7 and PH @ 5.8. Loaded into the buckets today but the EC and the PH have risen to 2.0 and 6.0 in just a few hours. Previously, the water was too hot and along with higher levels the seedlings are looking bad so I've been trying to recover them. But each time the readings rise. Breed: Ghandi.. Taken 2 days ago and looking worse now. It's 31 days old !! I'm guessing I should lower the levels so …

just went into my grow room to find res near empty and water all over floor.On closer inspection discovered one of my pots overflowing.I lifted the pot out to see what was going on to discover roots had grown half the length of my return hose.I cant deal with this at the moment(have fixed immediate problem but this will probably happen again).So in the morning i was going to organize overflow lines on each of the pots,but this still doesnt solve all my problems so i would really appreciate some advice on this as its stressing me out.I have 20 litre sattelite pots with perlite as the medium.

After doing a bit of reading I have discovered that Neem oil, and specifically eco-neem is a good way of preventing pests in your garden. This year I'm doing a organic guerilla grow and was looking for a pesticide that someone can recommended to protect my plants from these little pests. I read a few times that people said Eco-Neem is not meant to be used on plants that are going to be consumed, making me a bit uneasy about the whole thing. Anyway all I'm after is a harm free spray that I can apply to my plants when I visit them to give them the best chance of surviving attacks, so something a long the lines of a Neem based product I'm guessing, or maybe one of those hom…

My first grow is going great guns, my system is working perfectly and I have three seedlings in there which are all from different bagseed collections (so different genetics with each one I would guess). I have one plant which is growng at the same rate as all the others yet it concerns me that it is a paler shade than all the others, I just took the ec up from .8 to 1.6 and started automated feeding in the last week. (see pics) can anyone help me work this out as I can not seem to tell why the plant is a different shade than all the others. (is this normal or is it a deficiancy or a nutriant problem?) to see the stats on my grow see "My first grow" by sassman (i…

Hey guys, I'm looking for some advice as to how to treat this plant. I've done a bit of research, and I'm fairly certain that the problem is phosphorous deficiency. No idea what the strain is, plant is about 2 weeks old, using 250W MH in growtent with exhaust fan and pedestal fan for circulation. This is strange however, given the soil claims to contain "controlled release fertilizers" (Yates premium potting mix). The plant seems to have slowly gone yellowish and has a rather large deep purple blotch on one of the leaves. I've fed it some ferts (Miracle-gro 15-13-12) to try and bring the phosphorous levels back up, and I'll test the soil pH asap. Any ideas…

Hi all, on grand final day i planted 4 seeds, super lemon haze, opium, jack herer and purple #1. After having germinated the seeds and being soaked in yesterdays great sun (not sprouting though).........I thought they would be great. But after no sun today and even worse conditions forecast tomorrow i'm worried they won't get enough sun. My question is I have a 400w hps and i was considering chucking them under it from a far distance and trying to match the daylight hours??, or should i leave them outside and hope they make it through tomorrow. If anyone has advice please let me know, Cheers
