Starting first grow, question

Indoor Growing Grow Room

A question from a fellow grower:

this is my first grow and i havent start yet

I have make a wooden box 130 x 130 x 300 cm

for ventilation i have two iso max can fans 870m3/h 3 speed one for the intake and one for the outtake, the outtake with the third and max speed 370m3\h and the intake at speed 2 and i have lowered at 7-10% the speed with a dimmer

i have a growzilla reflector if you heard of it it is air cooling and it takes 2 bulbs, i have one 600w hps and one 250w hps

when i bought the grow equipment they told me that with those isomax fans i will not have any problem with the heat runing 850w hps because they are preety strong…but the heat it is a verry big issue…

the temperature out of the growbox its about 26.1 celsius and inside the growbox with only the 600w hps it is about 35-36 at 15 minutes i havent try more…

the exaust is going with ducting at the window straight out and the intake is in the room

maybe it is because i have put a lot of isulate duct with a lot of bendings but i cant do with less ducting because i have verry big problem with the noise i live in an apartment with not good soundproof walls and celings so i try to keep it as stealthy i can and maybe thats a reason
the reflector have flanges for 6 inch duct and my ducting is 8 inch , i test it and it cuts about 7-10%

As you can see in the first picture the intake is down and i will put a shelter on it and the connection Y there at the bottom the two ductings when they are out of the box they do something like a C and then they go back inside the growbox again…i didnt do the holes on the shelter because i want all the space to fill it with plants…

now i have done a big research on this and i have one question i cant solve by searching in the internet if i use an airconditioner i can run it to speed 2 the outtake and speed one the intake if i can control the heat ? or the plants need max speed of the ventilation 870m3/h it is the filter that cuts at least 20-35% thats why i have the fan at the bottom at 2nd speed…

i know it is much for first grow but i want big yields

if you can advice me somehow i will be grateful

Thought I replied to this last night. 130x130x30 cm seems really small. I cannot make out what is going on in your piks. They are to dark for my old tired eyes.

Plants need to be grown at 21-24 Celsius maximum for best production. You probably know that. Having temps in a range from 31-35 Celsius(87.8 f - 95 f), is too hot for the plant to achieve proper growth.

Please let me know if your size specs are correct, centimeters?

Peace, lw

all the box is 3 meters height but with the shelves you see the free space between the botom shelve and the reflector is 150cm: one meter and 50 cm and without the reflector is 200cm: 2 meters

unfortunately i cant efford for an ac unit…and it spends a lot of electricity and the electric power will go of all the time its a bit old house…

i was thinking of the hydrofarm 8" Ice Box Heat Exchanger (cant post link) i dont know if that will be effective but it doesent spent watts…

if you have a better solution or if you have try this icebox i will be gratefull to hear…

thank you good day :sunny:

How much is an Icebox, and why can you not post a link? All you do is copy/paste the url into your post. IN fact; I just dragged the url from this post into this reply
