 I have 4 seedlings growing germinated around 12/11 they are looking very healthy but some sort of bug is eating them. 2 of the seeds i germinated were eaten just as they hit the surface and the round leaves on the 4 remaining are being chomped on, one of the leaves is almost torn in half. they have already developed their 1st set of true leaves and these havnt been touched by the bugs. what is this? slugs?

 I just noticed I have about 50 tiny tiny black (white when in black tray) little bugs that like to swim and jump around in the water. They are too small to take a picture so I put them under the microscope and drew a picture. Any idea? What should I do? I have already cleaned the system with bleach water and have fly traps.

 Hey people im new here and pretty new to growing. I have come into what mostly likely is a noob problem. I know what I did wrong and have learnt from my mistake. I brought in these clones from somewhere else and they have carried red spider mites in with them I didnt spray them the first week because I thought it might hurt them. It is now the third week I probably noticed them to late but I have been spraying them every 3 days and trying to keep the plants themselves and the room air moist. Are there any other things I should be doing? Your help in this matter would be much appreciated. Last reply by Radic,

 Found the first one chillin on my plant (outdoory), and the second while trimming. They don't seem to have done much damage if any. I've never seen them before and I'm just curious as to whether anyone knows what they are? Cheers Last reply by Radic,
