ThHi everyone, thanks for the input as always. I just noticed a green algae or mold forming on the lower half of the inside of my seedling cups. I am using coco coir in 16 oz translucent cups with a ring of holes about 3/4" up the side as well as holes on the bottom. If anybody had this happen? Will it dry out on its own if I slack off the water? Should I change cups?
I noticed this just before their nap time, will up pics shortly.
I would also greatly appreciate some knowledge on the best way to water these babies.
Thanks to all
The green mould is due to light getting into the rootzone,if they're ready to transplant do it but not into translucent pots,if not ready for transplant then cover outside of pot with tape to keep light out and let rootzone dry for a day then back to normal waterings,good luck,76Hi everyone, thanks for the input as always.

Sorry, but that's incorrect. I've grown for years using all sorts of containers, including those that let in light. Yeah, some algae grows, it doesn't bother a thing. That's my direct experience.
the green mould can affect your success rates with clones,and generall vigour in seedlings to if it gets out of hand,you can get it growing on your propagators too,a 5. Percent bleach abd water deals with that though,76u can buy 16 oz colored cups, put holes in bottom of them and insert your translucent cup inside it like when u buy them. will block all light and u can pull it out and observe algae and root zone as well as ur coco drying out. had a friend who liked to do this to watch rootgrowth when comparing root products. transplanting young seedlings from cups can be a risky business. peace
What happens when the algae grows? Do you think perhaps some light is blocked? I have never observed a set-back in growth from using translucent cups. :)
Thank you for picking up what I was putting down. I figure that *if* the light is 'causing' a problem, it's that the roots would be treating it like the soil surface and nothing more. Thing is, I've watched the roots circle in those cups, too, so.....??Task creep is a curse.
So the reason not to do something is because it's not needed.
Seamaiden may be wrong, but that's not the point.
She is reporting experience that does not line up with common practice.
This makes it more interesting.
Why is it hard to observe germination times and rates? What's so hard about being able to compare that? I've been able to do that, and have used both types at the same time--no difference. See above rest of post. I think it's being anal at this point to insist one cannot use anything that might let light in. Maybe it's because I've not only never had a problem, but never seen a difference between plants started in a translucent cup vs non-translucent. Maybe you should try it yourself first before saying it "can't" be done.It'd be hard to observe such a thing. When I grow in dixie cups using cap's I generally get vigorous root growth along the entire outside of the cup. Up down and all around. Such growth would be limited by light.
Light causes growth inhibitors to build up in root tissue. To me it seems not a risk worth taking when transluscent cups cost essentially the same thing as do the opaque ones. Again, why reinvent the wheel?
Well, the plants look fairly fine to me, so I'm not sure where or what the problem is outside the algae not being pretty. I would also be similarly concerned about watering with that small a volume and it being what appears to be rather course coir, which I don't believe holds as much moisture as finer coirs will.Thanks everyone for the input, being a noob I was nervous. I transplanted 3 out of 6 to fresh cups, they seem to be doing just fine. They all look pretty healthy to me, I would greatly appreciate a look see.
Here are the facts
1st grow, well 2cnd if you want to count the 1st Fkup. New England grow
Tent in a shed outdoors
600 HPS in cool tube
400 HPS vertical supplemental (I cycle on/off)
Temp 75-81 degrees
RH 45-65%
Strait Coco Coir (Thanks Bozo)
Nothing but 6.0 ph water in the beginning / 1/4 strength Coco Canna after 3rd set of leaves, just now moving up to 1/2 strength
All are from seed, all are Ash )Af/skxAf/hz) except for the 1 marked SS (the only one that smells skunky already)
The big one is left over from my 1st attempt from a sprouted seedling into that 3 gl pot (one of my many noob mistakes, breaker blew, froze all except this guy)
I think they will be ready to transplant next week. I am setting up hempy buckets ( Thanks again Bozo)
Does anyone have an opinion on soaking the coco in a light nutrient solution to get it ready for transplanting?
Is there anything I should be aware of when prepping the pots?
One of my biggest fears is watering, I go out of town 2 days a week, I currently leave a little xtra water in the bottom of a dish or now another 20oz colored cup for them to drink up while I'm gone.
I'm thinking that's where the algae started.
The pics are not that great, I don't think it's the camera though. lolView attachment 406238View attachment 406239
I just want to say thank you to all on this forum, as I read through these pages I have learned so much more than just growing cannabis, through all of you I have grown myself. Thank You!

You mean observing the plant over its life cycle..? What about being able to see and directly compare amounts of leaf matter, canopy, overall size and health? What about being able to compare what we're really after, which are pounds per plant? You'd be surprised how little the cup of choice affects the final result, especially in relation to all other factors. It's silly that people get so caught up in this "Oh my God you can't let light in!" thing.What you'd be looking for is differences later in the life cycle stemming from stunted seedling root development (and the build up of anti-growth factors in root tissue--a known effect of exposing roots to light).
It shouldn't have any effect on germination.
I never said it couldn't be done (as your quotations would imply), I just wonder--given what is known about the effects of exposing roots to light--why it would be done.
