Water weight not going down solo cup

[NapkinB]

Hey, I watered my plants in my red solo cups and one of the 8 plants won’t go down in water weight and it’s staying the same weight. I watered it 3 days ago and it was at 180g before and 231g after I watered it and now it’s been at 197 for two days and not losing the water weight. I have tons of drainage holes all around the bottom of the cup.

Also I forgot to mention I’m watering by using a scale. I have messed up and overwatered and under watered every single time I’ve tried to grow so im trying to get it right this time. Im growing in fox farms ocean forest my temps are 71-81 and humidity at about 65. How much water weight are they supposed to lose before I should water them again??

Don't use a scale. Use your finger. If it still feels wet don't water.

Can’t stick my finger all the way down to the bottom. Top inch or two is always dry.

if the solo cup is 200ml volume then 50ml of water sounds about right.
though it's dependant on medium used... get a feeling for that in the first place

Water it until water flows out of the holes in the bottom. And water every 2 to 3 days when you feel the top and it feels light or is shrinking away from the edges of the cup.

Yeah today would be the day I need to water. But the water weight has stayed at 197 g since yesterday. The rest of the plants have lost about 40g of water weight. This one has lost 30 and won’t go down anymore. Stuck a stick down into the side of the cup and it came out wet.

You can cut open your cup and see what’s going on and then either tape it back together, drop back into a new cup, or up-pot. If you slice (or just tear) up the sides (from drainage holes) and remove half the cup, you can hold all the dirt together in the other half and it’s real easy to manipulate. You’re only in the cup for short time so easy enough to just taping the cup back up.

Use a clear cup. Place it inside a red cup. If you want to see your roots.

Do you know how much of that 50ml of water should be gone before watering again?

Or you could just put the cup in another cup without taping

It could be that the roots just haven't developed like the others have (yet). I think the clear cups inside a red cup is a great idea. I don't even bother with the red cup though, since I'm going to upsize anyway.

You have to account for root growth in your equation... There can be an explosion of mass beneath the soil adding weight... Roots grow much faster than the greenery

Bro the soil in the pot will hold always the same amount of water when fully saturated - but how much it is in this case is different to each mix regarding the various ingredients used. And ofc, how big that volume is in the first place ;)
Usually 1/4th to half of potsize in ml.
Earth needs to be fully made wet if proper aeration amendment is present, then wait until most free water has been taken up by roots or evaporated.

I water when the pots get light don't use scale as u can tell when they need water how? The pot is much lighter and leaves get a bit droopy.

What's the weight 24 hrs. later?

Marijuana Watering, how media, pot size/shape and environment affect it

Ok lots of posts on how to water plants. So I thought I would put together a thread on how different factors contribute to different results that ppl see. This will be a long read based on my personal knowledge, opinions, research and others work to consolidate information for our members. I'm...

Watering SOIL

New Simplified Way to Water Marijuana Plants

The other day I had an idea and after testing, it works great. To know if you need to water, get yourself a soil meter. Poke or drill 4 holes in your pot 1/4 way up from the bottom spaced around the pot. Insert the meter probe into the hole and test for moisture. If its dry, then water SLOWLY...

When you finish watering, make sure you water the around the outside inner edge of the cup because that's where the roots are LOL.

I think he missed an important step, without perlite in that soil it’s going to waterlog. Repot it in a fabric pot with added perlite or remove all that wet soggy dirt and water much less frequently in moist but not wet soil.

You also should avoid saturating it with water, you need way less when the plant is small or in a small container like a cup.
