My tent is 1.2 by 2m so 4-4 I believe, I have 600watt dimmable ballast but if I run the 600 setting the temps reach 30 celcius so way to high for long periods, I only have around £150 I can chuck into it as spent so much already, and most of the 150 will go on.a dehumidifier this week so unsure how to lower temps enough to.run the 600watt let alone 600 bosst setting =-( and need largest yield possible from this to last me til next harvest.
Do you have an exhaust fan ? how big is it ? A decent exhaust fan should be able to shift enough air to easily cool a 600w hps in a 4x4 space. Another better option is an air cooled reflector that is linked into your exhaust fan. Air from the tent is sucked into the carbon filter and ducted to one end of the reflector and out the other end to your exhaust fan and expelled out of the tent and preferably out of the room. If you continue to have issues with humidity I think this set up is a better long term option for you.
I will look into an air cooled hood today, see the prices =-) they gave me a 4 inch inline fan with the tent…it was supposedly the right size, but I think I need a 6 inch one tbh…the negative pressure is enough to suck the tent in, but d isn’t cool enough.
Without knowing what medium and nutrients you are using , I would say she might be a little hungry,
Biobizz light and all mix with ionic nutrients, currently grow nutrients - high nitrogen…i did start feeding rarther late as didnt know how long soil nutes would last, going to switch to flowering nutes soon, also have PK boost if needed.
