Why did my marijuana plants die ?

Question

I had 18 seedlings that sprouted and they got a few inches long then they rotted off at the base of the stem why ?

What are the conditions it needs?

Answer 1

What you've described sounds very much like a root-rot called "Rhizoctonia solani". It is a fungal disease (small dark lesion at the base near soil level) that attacks seedlings at an early stage and they basically rot and die. This disease seems to favor warm temperatures and wet soil conditions. Since it attacks the vascular system of the plant, it cannot transfer food or water to and from the roots.

It is found in all soils and will survive indifinitely. The disease can be transferred very easily with water, your hands, infected tools, mixing of soil contaminated soil media with new soil, containers not being sterilized, etc.

Whether it is Rhizoctonia or any of the other diseases that commonly attack seedlings, I'd recommend you do the following to eliminate further infection of your plants;

1) Sterilize your tools and container pots with
-Boiling water
OR
- Isopropyl (rubbing) alcohol

2) Use sterile bagged soil (not leftover soil from previous crops)

3) Purchase online a product called; "ROOTSHIELD" from americanagritech.com. "Rootshield" is a beneficial fungus that attacks and kills certain diseases that are detrimental to plants...including Rhizoctionia. You can mix "Rootshield" with water and apply it like a fertilizer onto the soil around your plants. It will protect your plant till they're harvested.

Hope this information was of some help to you. GOOD LUCK!

Answer 2

if you send me your seeds i will grow them plants big...girl- you can see update pictures occassionally as they Mature.
then come hang in Texas w/me & we'll harvest them/ dry them & smoke them while walking back from the river to my Barn
---oh yeah, what they said- too much water/ poor drainage probably. once the sprouts are inching their way UP-
give em direct light for up to 18 hours a day-
If you use artificial light source- try & keep the bulb far enough above the plants so as not to overdry the plant(s) & soil.
proper ventilation will assist in this. Then just moisten the soil occassionally- do like above responses- & stop by a garden shop for supplies---------

Answer 3

proberly to much water or not enough sun

ill give you a hint marijuana is a weed
literally
so that makes them easy to grow

go to a hydro shop there r some and ask them (say it is a tomato plant they grow in the same cnditions) what went wrong i need to see it to be able to comment in more detail oh and give me a call when your new plant has grown

Answer 4

probably because they werent getting close enough to light...and also males tend to be taller when they sprout so it was probably better that they died anyways...keep trying for that female plant!...start them off indoors, also..close to an artificial sunlight bulb...then once they get about 4 sets of leaves put them out side

Answer 5

they need to sprout then you need to transplant them in something bigger..make sure they have plenty of light..GROW LIGHT..works great..dont over water them..every couple of days give them a drink of water dont flood them..and most importantly dont get caught with them..you can do years in prisons for having just one plant...my uncle grows them and they get as big as a christmas tree..if you plain on planting them out side buy some CLEOMS...they are a legal relative to the pot plant and they look just like a pot plant with big pop corn flower blooms on them they even smell like skunk...they will hide the pot plant so you cant see it..

Answer 6

Black lights may not be the correct type of lamps. Sodium or halide are the correct lights for it. Stop the black and flouro lights, use natural light if you cant get halide or sodium, go for 12hours light, 12 hours total dark if you can control the light. Allegedly.

Answer 7

it's called "damping off" happens a lot ... too damp and not enough sun. It might have helped if you'd used sterilised soil but fungi are everywhere ...

Answer 8

Because you are a pothead and therefore incapable of keeping plants alive.

Answer 9

well, i don't know much about it except they need direct light. my friend had one and kept it on top of her stacking washer and dryer and had a lightbulb directly above it and it was always on. are you serious though?

Answer 10

too much water or fungus. make sure you use quality sterilized potting soil, and that water can drain away from soil.
