1st Grow -- Grobo Start to Grobo

Does it matter that it’s an autoflower?

The recipe currently calls for

10 Days Germination
22 Days Vegetation
14 Days Transition
23 Days Flower
10 Days Flush

How long do you think I should return it to vegetation/what am I looking for when to make the switch to Transition?

Thank – I really appreciate the insight.

Yes, it matters if it’s an auto. If that’s an auto, you may have issues. You can’t really slow down an auto.

I will let more experienced growers comment as I have only read about autos, I don’t mess with them. I like having control over my grow and with autos you give that control up.

To put things into perspective, this pic is of a normal fem proto and it is day 6 of transition.


Awesome – thank you for the picture so I can use it as reference! I think I may be 4 days or so behind because that’s how long it took to sprout. But then again, there is 10 days built into the recipe for germination.

I suppose we shall see.

After a couple of days in the Grobo Solid, things aren’t looking great. Hopefully she will be saved by the nutrients and lighting, but she looked so much better in the Start.


Need some better pics to help. Shoot pics with the amber viewing light on as it’s easier to see details. Also need a close up pic of the stem where it meets the cocoa pod and a pic of the roots.

Here are the 3 angles. Everything appears to be fine with the roots but perhaps not.


Well it looks like your air pump is working, that’s good. The roots look okay for the size of the plant and they don’t look to be suffering from any contagions. They are underdeveloped in the sense of where they should be in your auto receipt though.

Dampening off seems to still be your issue. I recommend adding a fan to help dry out the peat pod. I have had the peat pod in the grobo now for a few weeks and have noticed some signs to look for to see if your pod is too wet. If the entire top of the peat pod is uniform in color and damp, you need to take measure to dry out. A healthy peat pod will show signs of drying out in some areas and those areas are lighter color.

I bought 2 inexpensive usb fans on Amazon that work great. I use hook magnets to hang the fan. The extra air circulation keeps the moisture level just right for the peat pod.


Awesome — thank you for the feedback. Do you by chance have a link to the fans you purchased and a picture of them setup in your Grobo? I’ll get these ordered by tomorrow.

I then drilled holes in the base to loop over the magnetic hooks.


I’ve ordered the fans, I’ve added hydroguard, but it appears my real problem is water temperature. The room that it is in stays no warmer than 72 degrees, so it’s baffling that the water temps would be so high.

Wow, yes. 76 degrees is no bueno but the bulk of your issue is still the dampening off. I am in the same situation as you but came up with a very cheap solution.Easy Water Chiller Setup

So it turns out maybe it just took a little while for the temps to settle in. Today is hovering right around 71 degrees.

To help dry out the pod, I squeezed it several times at the bottom and have pried the holder up with these plastic pieces from the Grobo start.

Hopefully the fan will dry the top and sides of the pod. Any advice from anyone is greatly appreciated.


What day overall and what stage?
You may want the plant to be in early veg so it is filling to the medium water level. Or you can take some water out of the tank using the Drain process but just do it for a few seconds. You can lift the lid and watch the water level/sensors as you are draining.

Right now it’s on Day 3/14 of Transition. It’s a 65 day autoflower from Mephisto, so it has already flew through the veg stage. I’ll try to drain a little water tonight and see if that helps. Thank you!

Take a look at your picture underneath the lid. We can see water droplets forming on the underside of the lid which is too much moisture. If water is making it up to the lid it is surely soaking the peat pod. I’d remove some water and wipe dry the lid. Then check it after a couple hours. Hopefully water will not be accumulating up there.

Do you have an extra air stone going or something?

I have the same setup with the new lid and peat pod basket. I just checked mine and the underside is dry.


Wow – great catch there. Only one airstone, but clearly that is just too much water. I’ll remove some and hopefully she’ll dry out and be salvageable.

THANK YOU! I’ll update in a couple of days.


After removing some water and drying the pod out — I’m getting some slight discoloration to the bottom leaves. In general I think the plant is looking healthier today and the dampening off is hopefully an issue of the past.

Thanks for the help and hopefully she perseveres.
