Help with seedlings

vinoslatt_24 · May 28, 2020

The seeds sprouted with no hassle in the rockwool cubes. I transplanted into my base promix soil once a root came from the bottom of the cube & now the growth is minimal. This is day 8, I haven’t fed it any fertilizer yet, I was waiting for my 2nd or 3rd set of leaves to come in at least before doing so. Temperature hovers around 77-82 with the humidity between 40-45. I’m on a 18/6 schedule with a 100w about 20 inches away. My guess for the stunted growth is maybe the promix Hp but I’m confused because I’ve used it on previous grows with success and the ingredients are simple. I’m about to transplant these two again in some soil i found at my local depot to see if there’s a change. I just ordered some roots organic and happy frog too. Any ideas on what this could be?

100w is not a very powerful light so be patient.

Is it a full spectrum light? I recently got a rotating multi-colored flourescent light bulb and installed it -- fantastic growth spurt yet. The plants also like magnets and respond to magnetic waves, nothing fancy fridge ones OK. I don't see a reflector, but one of those car sunscreen jobs will do fine for wrapping it around your area, increasing light. I was priviledged to see the Edinburgh fringe festival and the sounds of the lone piper still send chills down the spine. Been watering with tonic instead of 'real' water and waiting 1 week in between. Thanks to Dire Wolf for setting me straight on th e bugs eating my earlier plants.

Im trying hard lol, this is my 3rd attempt. The one before this I kept the plants going for about a month, a 2nd set of leaves came in eventually. I took one plant out the container to see if there was at least any root growth, their wasn’t any. My other 5 seedlings were the same result. It seems like something is suffocating the seedling but I can’t pinpoint it. I’m determined to figure it though

True but they aren’t stretching for light or wilting because of it. Even under my t5 I’ve gotten the same result. I even went the jiffy route and the same thing follows

No reflector on my end but I have a tent Mylar wrapped where I keep them with the 100w. I transplanted again with a different brand, hoping to see any type of change within the next couple days and I’ll post again

No need to transplant, how often and how much do you water? For light, cut the dome off a 100w equivalent led, and about 5 inches distance.

This was the first thing I put on the board outside my tent two years ago. Love is the most common cause of death in seedlings lol.

Keep your nutrients to a minimum, flick her every now and then gently, don't let her dry out completely, don't keep her soaked either. Most important, give her space! Be patient. :)

every 5 days but it’s only because my environment dries out the soil eventually. I’ll give it a shot, only under the T5 is my light similar distance.

I transplanted again this morning, Into the same size though but with a different mix. I wiped my containers down just in case there’s a pathogen I’m not seeing. No direct change so far since the transplant, I was expecting transplant shock since I didn’t water immediately but it’s still upright some how lol

Yeah,40% humidity is low, you can put a dome on seedlings to increase humidity. I’ve use disposable plastic cake lids and cut the bottom off water or soda bottles.

It’s the hardest part of the whole game mate.
patience at every stage.

Just curious, is there a particular reason you chose to germinate in rockwool, and then into soil vs germination in paper towel method and then transplant direct to soil when your root is about 3/4 inch long? There’s a ph discrepancy between the two mediums, and I’m wondering if this is affecting you. Perhaps it’s simply worked well for you in the past? But yes, sometimes mate, it’s just time lol

I love the poster & yes patience is key but this is a reoccurring theme unfortunately. I just let my previous seedlings go 3-4 weeks looking like this to see for the late start but no results. before throwing out I checked the rootball and nothing was there bar the taproot basically. When I repotted into the Depot soil yesterday, it still only had the taproot. The last variable to change is my soil, I even brought a new humidity dome lol. Unfortunately the Depot soil I picked is similar to the promix so I’m not expecting a difference. Some decent news is that today i was able to find some happy frog & fox farm today so Im gonna plant a seeds later and see what happens. I’ll keep these going as well just in case of a miracle. Your girls look beautiful by the way in the tent

Don't take offense, I'm trouble shooting... Do you own a decent pH and/or E.C./PPM tester? I know they are a little pricey and require weekly attention in some cases ... they got me out of my seedling hang ups a couple of years ago.

I strongly suspect that may also help you. I tried the cheapo amazon special ones... They weren't of much assistance. I swear by my bluelab pens now.

My germination success in coffee filters under loose tinfoil, on a plate, in a warm spot is near, if not, 100%. I plant them once I see half a centimeter of tap root.

My success rate germinating in rockwool... 40% or worse.

I missed that in my first pass. Thank you! I'm a proud patient today! Lol

Agree I would skip the rockwool, good luck

To be honest with you it was the first method I was introduced to and it worked so I never changed. With my current mishaps I was looking into different methods and the paper towel & direct soil method. They were next actually but I was waiting for my new soil to come in first, then I would compare and see if it’s just the promix that’s causing the stunted growth. I learned online that some people do have ph issues with this sometimes, their answer was to mix dolomite lime into the soil. At my nursery today, an employee told me you could go half with promix and a Fox Farm soil for example. I used to mix with fox farm & coco but I ditched both eventually... sigh lol

Oh man back to pro mix an pH lol. I'm stepping out of this one. ;)

You're right though. Some soil in the mix will help stabilize the pH. I use pro mix and lime because its cheap. ;)
