Runtz try three

Looking dry doesn't mean they are dry, try feeling the weight of the cup to gauge when to water.
I know what you mean but I only added 3 ounces of water to a 20 ounce cup containing about 18 ounces of soil. My muscles are not sensitive enough to tell if the cup is missing 3 or less ounces and I don't have a scale right now to weigh these cups.

If you've watered them enough, and let them dry back enough, you should be able to tell the difference. I do it with 3" pots, which are about the size of your solo cups, and the difference is not subtle.

Try it on cups with no plants in them to practice, and keep those around so you can compare to what the cups with plants in them feel like. Also, picking them up by the rim helps because there is more torque, i.e. the difference will "feel" greater vs picking up from the bottom or sides.

The soil was pulling away from the sides of the cups so I gave them five squirts of water from the spray bottle, which isn't much.

So I was curling the plants and long story short I used my moisture meter to check for moisture. The MM is in the pic but has glare. That's the 5ml pipette I use.

The moisture meter read between 2.3/2.9 on a scale that goes to 9.9. While the plants look bone dry there is still moisture in the center. I'll let them continue to dry. The humidifier is in there so they aren't necessarily in jeopardy of complete desert like conditions.

Disreagard the three in the background. I'm trying to revive those from a previous grow attempt.

Looking good, you may consider lowering your light just a little bit to minimize how stretchy those seedlings get.

The back three are also looking pretty good all things considered. You can probably remove some of the older dead or yellowed growth from them.

Keep it up! :bigjoint:

These plants seem really dry. When I took the moisture reading the soil crumbled and one seedling fell over.

In the very centers the reading range is 1.3 - 2.1. It's 0 everywhere else.

Why are you making them so dry?

This is the 3rd crop and I've ruled everything out but over watering so.... these have been on a low-water diet.

I'll give them 3 ounces of water right now.
Ohhh shot okay yes that makes sense. Do you have holes In the bottom of the cup/pot and for seedlings if you have shot glass just give them 1 shot of water and see what moisture that says you don’t need the whole pot wet with seedlings it could kill them if they don’t dry quickly. I used 1 shot of water for a bit until the leaves were spread past the cup

Just my 2 cents, I don't understand pot growers' fixation on using solo cups, or any other container meant for drinking. I tried them for one grow and it was annoying enough trying to poke holes in them without cracking or splitting...I guess once the plants are growing they work just as well as any other container, but why go with something that requires modification right off the bat?

Why not use some 3 or 4 inch square nursery pots? They're not expensive at all, they already have drain holes of an appropriate size, and will last way longer than solo cups, plus you can reuse them...
Hehe I never understood that either, seem to see it on alot of pictures in the NA region.
In the EU you'd barely see those. I have small plastic pots with holes for vegging, they are dirt cheap.

Today the plants turn two weeks since drop & still look fine after that first watering.

I tossed the three from the old batch. The weeds were out of hand.

There's a pic of the spec plate on the back of the light. Indicates 400W.
I'm surprised you threw them out, they were just starting to look ok.. Just had to clean them up and remove the dead growth.

I only have two 400W LED fixtures for the 5x5 area. If my maths is correct that's only 32 watts per sq. ft. Not a lot of spare watts for canopy overlap.

I'm going to toss two more plants and only flower four.

I've got about a pound of of seeds from growing out stressed plants like those. Later I'd be cloning hemies. Not worth it.
Then you already are growing and will be cloning hermie prone plants if that is the source of all your seeds sooo, I guess six in one, half dozen in another? lol :hump:
