1st Grow -- Grobo Start to Grobo

Should I remove the wick now if dampening off is already becoming an issue? Any other tips for keeping it dry?

Thank you a ton!


Yes definitely remove the wick! By now your plant has roots hitting the water so you are good to remove the wick. This will help dry out the peat pod and fight damping off.


I open my grobo at least once a day and use mini fans to keep dry! Removing the wick now could help with the moisture! If you see any issues pop uo let us know! :eyes::seedling:


As @Bplatinum9 @miami5th mentioned, remove the wick now. I might even suggest gently squeezing the peat pod to remove the excess water. Give her at least a week to recover


Thank you everyone for the knowledge. I’ll be taking measures to keep it dry immediately…


Hey everyone — just a few basic questions as I head into making the transition to the Grobo Solid this afternoon.

  1. how much longer could I conceivably leave it in the Grobo Start before it becomes too tall and the light begins to burn the leaves? A few days? I’m trying to make sure I time it right for when I start my next plant in the Start.

  1. does anyone ever have issues with draining and refilling? When cleaning my Grobo Solid yesterday, I noticed there was at least a 30 minute period where I couldn’t get water in my reservoir. The app would tell me that I couldn’t fill because I was still draining, and then when I would go to drain it — it would tell draining has been completed. I have a call with Grobo support today to hopefully remedy this but didn’t know if anyone else encountered it.

On Grobo’s website it says you can save up to 5 weeks per grow. So you should be able to keep the plant in the Start for 5 weeks (give or take).

Maybe a power cycle will help with the drain/fill issue but I would advise chatting with Support first. Just note that if the machine does not complete a full drain/fill then the nutes will not dispense.


The transplant has been made! For a 65 day autoflower (Sour Crack) from Mephisto Genetics, I was a little worried that I waited too long. Today is Day 25 (day 1 of Transition) although technically the plant didn’t sprout until day 4. Still – that’s around 35% of the entire grow done in the Grobo Start. She appears to be doing well and I was amazed at how relatively easy the process was!

Now I need to read more about “leaf tucking” which is what Mephisto recommends instead of trimming. So far nothing has been trimmed. What do y’all think about leaf tucking instead of trimming?


I would adjust your schedule back to late veg, too small for transition.

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.
