Will do sir, I also read you can cut this sheet with tin snips and heavy duty scissors! Should make it a lot easier for fitment.

@Gunk Do you think the plastic will increase the light intensity like in an automobile. Much Hotter inside due to the light rays coming thru the glass.
I say bend the stems all over. They pause for a moment but turn back up towards the light in a few days. This buys you time. They are not growing up…
My advice is you have to start LST early in late veg so once you get to flower, you have the right height and the canopy covers the entire box.
Here is a picture just to make yo smile.
Happy Growing

I was not going to comment and wait and see what happens. 
I thought that too about the lights and even what is to stop the plexiglass from heating up some, then it is hot even lower down then???

Yeah I totally thought that for a second only. The light already has a thin piece over it venting most of the heat from it out from the top. Plus it’s really not that hot if your grobo is running in the 70’s. I think it will not affect temp or light intensity at all. Air flows out through holes and filter like normal. Plus it’s flat and plastic. Like putting a vented protective barrier I guess. I’m not a scientist but I’ve been around enough I feel confident. Back in the day I cut piece to replace my back cab window in a truck. The plexi was cooler than the glass.

I think it might work, but us 3 are on our very first grows I think, so maybe we should listen to others or wait for someone from Grobo to comment before modifying things like this.

I want to wait till my first grow is done before I go modifying mine, I might do it to my second unit actually I will have one unit for the control and the other just to grow regular like someone else mentioned on here they were going to do, One for all training methods and compare to the other units final weight and what not experiment like.

I get it totally. I hope I don’t have to do much as it grows. I haven’t done much as it is really. But if it does I’ll deal with it accordingly. I’m anxious to see what you get.

Quick question - just wondering if anyone has experienced this. But I’m spotting some moisture on the leaves, not all but just a handful.
I’m struggling to keep my grobo below 50% humidity. Would adding a clip on fan towards the top of the canopy help prevent moisture build up?
I have an Eva dry dehumidifier in the unit to help absorb some of the moisture but suspect its effect is negligible.
The last thing I want after going through all of this effort is to end up in a situation with bud rot!

I might remove the dehumidifier from inside the unit and add a small fan at the bottom and aim it up, that is what I did and many others.
Not even sure what my humidity even is, as I don’t check it, 40-60 is normal most say and even as high as 70% is fine.
They do have an update model.

Ok great appreciate it. I have popped one in underneath and pointed upwards as suggested.
Snapped a couple of close up shots as shown below. Can’t wait to see some buds developing properly

I have fans on the inside…
Try to install one.

That is extremely tall. What day are you on?

I am currently on Day 10 of Flower… I have pushed the coco pod into the reservoir which has bought me a bit of extra headspace, but it’s getting extremely tight. Clearly, I didn’t need to extend veg by a week earlier in the grow. At least I know for next time! Hopefully the stretch should be slowing significantly in the coming days?

You may have to bend some stems. Think about it before it is too late… the light will burn your top buds and kill the harvest. Better to be safe…

Would using something like the LST clips be ok at this stage and if so, at which point of the stem would you suggest applying?
Some of the top fan leaves are curling and showing a bit of heat stress, so definitely don’t want to risk the crop that’s for sure. Having said that I’ve seen some other grows all the way into the roof on here and successfully harvested, but this must surely have affected the quality.
Just no idea why my plant has stretched so aggressively, especially as GDP is mostly indica.

Plants don’t follow instructions…
The clips would work or even just gently bending with your fingers. The affect will slow the vertical growth.
I am afraid of you let her just grow, she may kill herself. They run toward the light… you will still get a harvest, it will just be damaged

Looks exactly like mine

Hi all,
Wondering if I could get some advice, as just noticed the following brown spots on the leaves and it’s concerning me especially as we’re getting closer!
I’ve read that it could be one of two things: Rust Fungus or Nutrient Burn. When I checked and rubbed some of the leaves, nothing rubbed off onto my fingers (apparently a way to check if it is fungal). I checked this a few times, so I really hope this isn’t the case…. Is there a chance this could be nutrient burn or perhaps also heat stress related as we have some leaf curl?
Any thoughts or experience in this dept really appreciated
