Testing out my grow box and it’s running at temp...
Grnheadstarted grow question 5 years ago
Testing out my grow box and it’s running at temps from 85-89 degrees. Will this hurt the plants in a hydro setup? I haven’t checked water temps yet. Any advice would be much appreciated. I have the Supercloset Superbox setup with SuperPonics 8.

Hi @Grnhead05! Indeed, temperature is a crucial factor when it comes to hydroponic systems. On the one hand, high temperatures will negatively affect the aeration of the nutrient solution, the plant will be more susceptible to suffer from root pathogen attacks. On the other hand, a too cold environment will affect nutrient absorbtion, increasing the risk of deficiencies and/or "seedling melting". If you cannot get the environment temperatures down (below 24°C - 75°F) then you must cool down the water directly, using a water cooler, they can be pretty expensive but it's 100% mandatory if your water temps remain above 20°C / 68°F. Hope this will help, let me know in the comments section if you need further information. Happy growing! 👊

If you can get your temp down around 77 it will give the best results unless you run co2. And you want to keep your water temp below 72 because the waters ability to absorb oxygen diminishes at higher temps. You can run the room at 85 and usually get good results but the heat can affect your end product especially in flower and cause issues in your hydro system.

When to flush and harvest and should I defoliate again?When to flush and harvest? I think I am close but my gut tells me to keep it on the current nutrients and feeding schedule for another week or 2 and then flush but also don't want to leave it too long.. My stash is all but empty. Also, should I defoliate again?

Defoliation for better ventilation?Should I defoliate/prune to ensure better ventilation? I am going to flip the plant soon. It is quite bushy with big leaves and sometimes it is difficult to water it as there are a lot of leaves down there.
And when is it better to put the net? Before of after the flip?

Some guidance for ScrOG please@22cm & preflowering for about 4-5 days. Haven't noticed any stretching (~2-3cm)
When do I start with the ScrOG and at what height should one set the net ?
Also curious about defoliation: Right now, I keep tucking the fan leaves under the smaller ones.

Defoliation (no horizontal room in my tent and a lot of vertical room)This may seem like a dumb question but is cutting these small lower branches off going to promote vertical growth in my plants? I will be doing it later on anyways to eliminate larf but would it be more beneficial now or is it worth to keep to take in light energy for now

Defoliation AutoflowerHey fellow growers,
How should I approach defoliation with autoflowers during flowering? I'm thinking of removing lower leaves, especially near the soil. I prefer to be cautious to avoid mistakes. Reddit wasn't helpful as it seemed too critical. I hope for better insights here.
