All fire up just checking the standing temps to see how much adjustments need to be done..Now for some goods news.. The mail man brought me an early birthday present today my new flower tent light has arrived Unit Farm UF4000. All hooked up and ready to rock and roll provided I can get these girls the distance.

I've cut the water right back watering less and less frequently their looking much better..Still looks like it may be recovering from too much water.
Had it running for 4 hrs got to a stable 25°C at 55% rh happy with that, the light looks amazing lit up..All fire up just checking the standing temps to see how much adjustments need to be done..View attachment 1253380
When mixed PH is at 7 now I'm using tap water it was 7.9 for the first few weeks with rain water..That soil mix looks much better. The cloth pots will help get air to the roots as well. Some minor signs of deficiencies. Are you checking the PH of your feed solution?
Will do.. I'm sure I can find some PH down at a nursery in the area..If you have some PH down and are confident in your meter the plants could access nutrients better if you could get that PH in the 6.0 to 6.5 area. Since it is already a tad high you might consider shooting for 6.0
Heat sink that power supply to concrete or metal. Wood is an AWFUL heat sink. By simply setting it on the concrete floor (or a sheet of aluminum about 2-3x the size of the power supply) , you will likely solve the overheating issue you're dealing with using the tent exhaust..Evening crew.. it's been quite a while since visiting this site and I'm here hopefully to post my first attempt at an indoor grow. Got a 3ft X 3ft tent that's only 6ft high and I'm already thinking this may be an issue. I went with 2 x 6inch Spiderfarmer exhaust units one to blow filtered air into the tent and one to remove hot air each fan 200cfm. This will also help to keep negative pressure throughout the grow. Also Spiderfarmer 3000W LED light board without a dimmer also may be an issue. I've removed the control board from the light panel and running it from outside the tent to keep temps down as I live in a Subtropical climate. Also using the cool exhaust air to regulate the temp of the control board to the LEDs hoping to improved efficiency and longevity of my lights. Only growing 2 plants at first to see how I go, I need to get some to germinate first. I'll be growing in non fertile soil as the medium and supplimenting nutrients.

Just wanted to be a bit clearer... by "sheet of aluminum", I mean a sheet about .5mm thick... not aluminum foil. However, you could stack sheets of aluminum foil and it might be a bit better than a solid .5mm aluminum plate.Heat sink that power supply to concrete or metal. Wood is an AWFUL heat sink.

Yeah I'm in Australia just started Winter but summer will be a different story. I'm not having issue with lights over heating at the moment but this will definitely help for summer when shed temp is rather high.. I think I might actually have a peace of aluminium down in the shed..Just wanted to be a bit clearer... by "sheet of aluminum", I mean a sheet about .5mm thick... not aluminum foil.

You can also buy good aluminum heatsinks like this for cheap: https://www.heatsinkusa.com/12-000-...JXNaP-E4f7KbnhZsO5g9QqLMpfvwr_JhoCCAQQAvD_BwE
Just make sure to use proper thermal adhesive and bond the heatsink to the power supply metal to metal... not over stickers or paints.
I'm in Arizona growing in a 4x4x7 tent in an uninsulated shop and summer heat is a serious problem... you're in Australia, right? Winter time... but I suspect summers can get pretty brutal there too.
This won't help with the light heat (but that's not much of an issue with LEDs), but heat shortens life span and kills electronics... and this can help protect the power supplies and extend their life.Yeah I'm in Australia just started Winter but summer will be a different story.

Will screwing the power supply to the alloy be fine as I think I have some 5mm..This won't help with the light heat (but that's not much of an issue with LEDs), but heat shortens life span and kills electronics... and this can help protect the power supplies and extend their life.
110f+ days, in an uninsulated shed with a metal roof... and a power supply that already runs hot... they aren't designed for that, but it's easy to DIY a minor upgrade and create a "sink" to "dump" the heat into. Also, with your tent exhaust blowing on the heatsink, it will be VASTLY more effective.
It will depend... IF you can get a good amount of the bottom of the power supply touching the heatsink, then the heat will diffuse into the aluminum and give a huge surfface area to bleed the heat off into the air.Will screwing the power supply to the alloy be fine as I think I have some 5mm..
