How much can I let the temperature differ ?

[Dr.Moggs]

Hello GWE!
I have had some trouble with high temperatures witch resulted in warm water and root rot.

I now have the windows open and the temperature differs between 22-27 in the tents. I know white widow is a forgiving plant.... but is this up and down of temperatures ok?
during light of it can get as cold as 19 °

As long as it’s not colder than 12 and no hotter than 30 the plant will survive. It’s not going to grow efficiently during peak temps but it will be ok

[Dr.Moggs]

Hello and thanks !
I'll keep that in mind , it's nice that they will survive l. But I want them to produce well also ,)

those temps shouldn’t be a major issue . Get some
Mycorrhizae and more air in your water and that will solve your rot issue I don’t even check my water temp anymore . Health roots don’t rot so provide them with good bacteria mycorrhizae and a bunch of air in the water and you won’t have to worry about water temp . My water gets into the mid 80s all the time and I haven’t had any issues since I made these exact same changes . Can I ask what the gph/lph your air pump is and if your using anything like orca or hydroguard? Also how big is your res . Here are some photos of what your res air flow should look like and the results it gives . If your res has good bacteria and mycorrhizae rot will be unable to exist.

Wow, Duck, that's amazing to me--temps in the mid 80s!! What do you use for air in water???

Agreed with DWD. Using beneficial micros like Hydroguard, I've never had issues in the past 3 years and my temps will routinely get into the 80's.

I use a gh airpump I think it’s like 720 gph I’ll have to doubt check it might be 1700gph but it is much bigger then the 240gph pump I was using when I had my root issues

DankwingDuck ! You helped me when I first detected the rot, thanks for that.
My reservoir is 300 L / 100 Gallons.
I have 3 oxygen pumps that pumps 8100 L/H in total.

I haven't been able to find any hydroguard or mycorrhizae, some things are hard to get where I live if you're not an certified farmer...

After cleaning the roots and the reservoir , seald all light holes and kept the temperature under 24°C my plants have started to thrive. New roots are growing and the plants looks better and better.

I really need to find some hydroguard and mycorrhizae, seems like it would make it all alot easier!!

[DankwingDuck]

The oxygen is the most important thing and you got that covered it seems . What are your border customs like . It’s likely you can order on eBay and have to shipped in if it will make it past customs inspection. I don’t know what the regulations are in your country

[Dr.Moggs]

I haven't looked in to the regulations but will check on Ebay. Problem it that it will probably take a while .

I will have to finish this grow without them two and with the temperature difference to keep the water cool.
