Help with slow seedlings

[AutoCrazy]

Hello,

I am a new grower looking for some help. First I will provide my grow room specs:

3’x3’x6’ grow tent
2 x 1000 watt full spectrum LED lights
6” exhaust fan filtered through a carbon filter into a different room in the house
Passive filtered air intake.
3 fans at various levels of the tent.

Grow conditions:

76 degrees
35% humidity
Water pH 6.2 - 7
Soil is Pro Mix HP with extra perlite and worm castings


So here is my problem. I have 3 seedlings that seem to be a bit small for their age (9 days old as of today). One in particular is smaller then the other two but all in all they all seem small. I have been watering almost every day due to the low humidity so this may very well be my problem (over watering that is). Although the top 1” of soil seems dry. I have been watering about 200-300 ml a day.

I will start limiting my watering in the intern to see if this helps until I get some feedback.

Also, should I just pull the little ladies and start over as I have more beans that I can start or just keep rolling? Am I over watering the ladies or am I missing something else?

Someone will surely chirp in soon!

I'm also a new grower and on my first attempt. Killed one already lol but just looked through my photos and by day 9 mine where much bigger than that. Are you counting it from day of planting the seed or from sprout?

I grow in coco so been watering it daily..2-3times pending if I'm home or not while until I turn on my Autopots. With soil I don't think watering is needed everyday and could lead to over watering.

Thanks for the reply. 9 days from sprout. I think I’ve likely been to generous with the watering. Gonna back it off big time. Might just cut my loses this weekend if they don’t show more growth and start again.

Hang in there and be more patient with your babies, they want to live. Seedlings have very little roots, as they are now developing in this stage, so plant growth itself will be slow because the energy of growing is happening in the root zone. Also if you have been over watering which is a common mistake, it can stunt them. The small root system needs oxygen to develop, to much water depletes the 02 levels in the baby root zones... We are here to help, I love these plants and want all to be successful in their grows, in the future try and get us images in normal light so we can also assess the color of the leaves for further diagnosis of issues. From what I can see, they are small but do look ok...Sometimes this is what certain strains will do....

Here is my Red Poison baby at 9 days from popping in the dirt. Extreme care and a dedicated grow LED light was provided for her, as well as foliar feeding, she is documented in my grow journal.

Your plants will greatly prefer humidity above 60%, and are probably being stunted by the low humidity.
Following this chart will produce profuse growth.
Subtract about 5 F from air temp to get leaf temp, then stay in the green area of the chart:

In soil, water to some run off, then let it dry well before next watering. Get used to feeling the weight of pot with a thumb and index finger lift. Soon enough you will know when they want to be fed.

Wow your red poinson looks great! I’ll check your journal out.

I ended up pulling the smallest of the bunch . It was not growing at all and I figured it might not as the tap root got damaged during germination so it really never stood a chance. I have a limited size for grow space so don’t need to waste it on a plant that looked like it wasn’t going to produce.

I will give the other 2 more time but in the mean time I have started to germinate 3 more beans ( 2 cream manderine xl autos by sweet seeds and a northern lights by canuk) just in case these don’t pan out. I think the biggest of the three will pull through if I don’t kill it with too much love lol. As for pictures in natural light, I will be sure to get those up next time. But they are nice and green so I don’t think there is a deficiency or something wrong that way.

I think I just fell victim to overwatering and perhaps low humidity compounded my problem.

Also while I have your attention. I have two 1000 watt full spectrum LED lights and have them about 28-30 inches above the girls. Does that sound like a good distance for seedlings? I’m not use to the indoor growing yet! I find outdoor in my greenhouse way easier!!! I haven’t run into any issues growing until I decided to try indoors.

Thanks for the info. I have tried to maintain the humidity better but even with a humidifier going I can only keep it in the 35-40% range thanks to the dry winter air we are experiencing. Any suggestions how I can up it on top of using a humidifier.

My exhaust system seem to just pull any humidity right out of the tent!

Thanks for the reply. I will try this method on one and see how it plays out.
