How HOT is too HOT

[Conasiour]

Just wondering if 40'C is to hot for flowering, im in nrth Qld it gets really hot here during the day,but im not sure if 40 is too high ???????

It would depend entirely on the strain you are growing, you will need to ensure the ladies never dry out with that kinda heat.

 

If a Co2 solution that doesn't add any additional heat fits your budget you would do well to Co2 enrich.

Iv been thinking about Co2 for awhile but its expensive

local brew shop small bottle is $260 not sure how much and where to get a gas regulator cheap enough

Mate im in NQ and last summer my room temps were hittin 39C. They survived but only just.

Ive since spent some money gettin aircooled hoods and air con and the temp now at the end of winter is still bloody 32! Take my advice and dont buy a portable aircon-regardless of how good it is.

As to CO2, dont waste your money on it at the brew shop. Go to BOC, pay deposit on a big bottle, buy a cheap regulator (if you look at the auctions or pawn shops you'll get one), and refills are then under 100. Its been awhile since Ive worked the trade but a Gsize used to be only $54 for a fill

Hay calaman cheers for the info

 

Been saving up for a air cooled hood, does it make alot of difference

From my experience high temps are no issue if you can keep the roots cool. If anything they increase resin imo especially if it's dry air. Maby go DWC with a chiller? It's easy to regulate the root temps then. One of my rooms often gets over 50 here in summer with the lights off in the day. Imo I get the best buds when it does. If you cant regulate root temps then yea it's a problem. Lowering the nute level seems to help them cope a bit better with it I've found.

 

Peace MongyMan

You need to be keeping an eye on the root temperature, especially if your doing a recirculating grow. Soil type grows are a little more forgiving when it comes to temperature problems indoors.

Room temp can be anywhere from 10 - 50 degree Celcius but you want to keep the roots as close to 18 - 22, it's very important and could be why your posting pics of fungus gnat problems elsewhere here ... although bringing soil indoors can cause that problem too. Keep at it, you'll work it out

Iv put a temp. gauge down near the roots to c how hot it gets prob. take an hour or so to see.

heres a couple of pics i thought mite take sum while i got a working camera

Definatley use an aircon if inside, to keep temp at 29C MAX

 

You will use shitloads of Co2 - 10L/month per 1.5 squared

 

Cooltubes only!

 

Root temps NEVER above 26C!

another cheap way to add CO2: put a beer fermenter in your growing room. Mind that at those temperatures it will run for about a week before you get a keg of beer - material cost about $15
