1st Grow: Flowering 2nd week. HERMIES?? :(

  1. Hi there,

    I'm towards the end of my second week of flowering. The girls are starting to produce flowers. I'm not sure if any of these are signs of hermies or if they're just preflowers. I took a good amount of pictures. :confused:

    Please help me identify them :(

    Thank you!

  2. i dont see any balls yet look like a female to me
  3. Oh, all of them?? :O
  4. Picture three is definitely a female pistol. Most of the shots are too blurry to really tell if there are pollen sacks. If you think you may have hermaphrodites, start looking for the male bus on the bottom of the plant and work your way up. Mild hermaphrodites usually bud male towards the bottom of the plant. Check for male buds every couple days until harvest if you’re not sure. If you find any, just clip them off.
  5. I was examining the girls today, and I noticed that one of them had a few extremely tiny white worms on top of the coco o.o I googled it, but I can't find a thread talking about the same thing.

    I scooped some of the worms out, but there are still some coming from the inside :( not sure what to do


    Thanks for the help
  6. Mm I'm not sure. They're super small. Like a spec of dust. Shaped like a worm
  7. Picture 3 does look female, picture 2346 looks somewhat female but its too blurry and may be too soon to tell.

    Wait a week, get some more shots :) Should be easy then!

    My last harvest had no hermies or so I thought. I got about 15 usable seeds and maybe 30 half formed seeds. I never saw a single ball on any of them the entire flowering process and have never grown a male past its starting to show its sex. No clue where I got pollen in there from, hermies can be devious..... and hide! just like trannys in real life. Check extra close!
  8. you probably see the calyx, which is totally normal, and is a part of the female plant. It's where seeds WOULD grow if it were pollinated. I thought I had hermies my first grow too, but htey were just calyx's

  9. good to hear :)

    i'm gonna bring in a better camera tomorrow and take pics of them. i have that little worm problem right now though :T

    i'm wondering if it's because i use wooden popsicle sticks to label the plants?
    they have been in the coco for over a month.
    when i pull out the popsicle stick, i noticed maybe 6 of them on there.
    i just pulled out another 2 sticks, and 1 had two worms on it, and the other none.

    i bought the ortho fruit and veggie spray and sprayed the top of the one plant that i noticed had some on top of the coco. not sure if i should spray other ones? (ie the one with the 2 worms on the popsicle stick)?? :confused:
  10. just took the best picture i could of the little worms... the tiny white dots are the worms. i noticed a few larger ones that are clear colored.. i'm thinking those are the grown version of the tiny white ones?

    the larger ones are maybe 1/5 of a centimeter long...

    should i spray the top layer of coco for all of the plants? or wait?

  11. They could be fruit fly maggots, but I honestly don't know. Someone else would have to confirm that.

    Like everyone else has been saying so far too, I definitely don't think you have hermies on your hands. It just looks like they have elongated calyxes.
  12. They look like Sciarid fly larvae. Google them. Bad news.

    Sciarid flies, also known as fungus gnats, can be serious pests of herbs. The larvae damage the roots of young plants, leading to poor vigor, wilting and even death. Adult sciarid flies can also carry important fungal pathogens e.g. Pythium. Sciarids are often present as secondary pests on plants affected by root disease, the larvae feeding on the rotting plant tissue and fungi. :eek:

  13. Nooooooo ! :,(

    What should I do??? It's 3rd week of flower, and I just sprayed the top of the coco with that ortho fruit and veggie bug killer :(

    Data Sheet - Sciarid Fly

    To the naked eye, Sciarid and Shore flies are dark midge-like flies found on and around the growing media of glasshouse crops and plants in interior landscapes. It is important to distinguish between the two flies. Shore flies are mainly just a nuisance, although their back frass can reduce plant quality. Sciarid fly on the other hand is a damaging pest. Their larvae feed on plant roots, checking growth and sometimes leading to the plant’s death. The adult flies are capable of transmitting plant diseases.

    Sciarid flies, which are also known as fungus gnats, are attracted to organic matter in the growing media and decaying plant tissue. It has been suggested that they are particularly attracted to media containing composted material. They are especially troublesome in some pot-plant crops such as poinsettias, and in the warm, humid environment of the propagation house where life cycles are quick to complete.

    Some of the newer chemical controls are granule formulations targeting fly larvae, which must be evenly mixed into the growing media for best results. Trials by the HDC have included an evaluation of the effect of insecticide granules in the plant plugs when control is difficult to achieve.

    There is a reasonable choice of biological controls for Sciarid fly but creating the environmental conditions that discourage flies goes a long way towards keeping them at manageable levels. In interior landscapes such as offices, that includes finding somewhere else for staff to empty the dregs from tea and coffee cups as such action can foster ideal breeding conditions for this pest.

    How to recognise them

    Adult Sciarid flies Lycoriella auipila are 3mm to 5mm long, black with long, tapering antennae. They run or hop more than they fly over the compost surface. They are most often encountered in heated glasshouses but the can be found outdoors too.

    Larvae are legless and translucent 6mm to 10mm in length with dark, shiny heads. They mainly inhabit the surface layer of the growing medium so are difficult to find although you may see them underneath leaves flush to the media surface.

    Shore flies Scatella stagnalis are slightly longer and broader. They have stunted antennae and white spots on their wings. The larvae feed solely on algae.


    Both types of fly lay their eggs in moist potting media or wet patches of soil under gutters or around the edges of polytunnels. These hatch after several days. Larvae feed for about four weeks before pupating.


    Plants attacked by Sciarid fly larvae are weakened and stunted. Young roots are eaten away. Larvae can sometimes mine into cuttings. Feeding damage creates entry points for root disease such as Pythium. Adult flies have been shown to carry fungal spores.

    Treatment – Biological Control

    Hypoaspis predatory mites feed on Sciarid fly larvae in the surface layer of the soil or growing media. They can survive for several weeks in the absence of prey so are a good choice for a preventative treatment or where pest populations are at low levels. A minimum temperature of

    11C is needed for mites to be active and for eggs to hatch. Hypoaspis also has some activity against Shore flies.

    The parasitic nematode Steinernema attacks Sciarid larvae, including those that have tunnelled into stems. Apply as a drench when compost temperature is between 10C and 30C.

    Adults and larvae of the predatory Rove Beetle Atheta coriaria eat Sciarid fly, Shore fly and Thrips larvae and will kill more than they need where pests are at a high level. The advantage of the control is that, introduced as a mixture of beetles at different stages of development, they are effective over a range of temperatures.

    Treatment – Cultural Control

    Large numbers of flies can be caught on sticky yellow traps, such as roller traps, which are sticky on both sides.

    Avoid over-watering. Sub-irrigation helps to keep the compost surface dry, preventing Sciarid fly from breeding. Alternatively, a topdressing or mulch will have the same effect.
  15. put a layer of sand on the top of your soil. about 1-2inches. a 50lb bag of play sand from home depot is about 3 bucks. they dont like to lay eggs in sand. also can set up some home made apple cider vinegar traps. just google how to make them tons come up

  16. But I don't see any flying insects :/ they're mainly In the roots. Would those 2 methods still help get rid of them? 0.o
  17. the sand on top of the soil prevents the adults from laying more eggs. and the ones in the soil should die off. the vinager traps will catch any adults and kill them. the ones flying could be hard to see they are very tiny. iv seen 1 or 2 flying around my closet and i hunt them down. also with your fingers mix around the top soil dont have to go deep at all just the very top... and see if any come flying out could be very hard to see
  18. thanks :) i'll try that today.

    i also need to water them today. should i water then put the sand on top or does it not matter?
  19. yes you can pour the water over the sand doesnt matter
