You may see from the pictures aspects of my setup, however just to clarify:
1 X 400W HPS bulb/ budget hood
1 X TT125 extraction + carbon filter
1 x TT100 inlet
1 x 3 speed oscillating fan
1 x 3 speed oscillating air cooler/humidifier
Room = 2.2L x 2.2W x 1.8H (big for 10 plants I know but will be a bigger grow when I have confidence of growing the 10)
Humidity 50 - 60
Temp night 72f - 75f
Temp day 75f - 80f
At start of 5th week 18h light 6h dark
Feed was:
week 1 Clonex only
week 2 Clonex & Canna A + B
Week 3 & 4 Canna A + B, senzime
Week 5 (now) Canna A + B
Half a liter each twice daily (10l pots)
Medium is Coco = Pea gravel

Please advise if you have any good advice and i will up your ratings accordingly.

(please ignore the 2 bad looking plants, I am aware of the issues here)

Cheers

damn man thats a nice setup for a first grow. awesome. . the one small thing i might suggest is if that "air cooler/humidifier" is a swamp cooler, you might want to get rid of it, because if your humidity levels are above like 50-60% your chances of bud rot or mold and such get pretty high. during veg its probably alright but in flowering keep an eye on your temp/hum to make sure that thing isn't makin things all soggy lol. but ya nice set up and good luck!

Yeah i had read the other day that i should aim for 30 - 40% hum during my flowering stage. It is a swamp air cooler but this will be empty during flower and used as fan only. A dehumidifier is also going in on a timer to keep a 30 - 40% balance during flower. I aim to be 30 - 35% Hum in final 2 weeks of flowering. Cheers for the compliments on the set up 2!

Your plants look awesome! The only thing I could think to suggest, if you are planning to do a perpetual grow, maybe keep the 400w for vegging, and invest in a 600w for flowering - for 10 plants you would get better results I think.
Welcome to the forum and good luck!

Cheers DoeEyed!
Yeah I agree, after reading to get more informed, I think I will be purchasing an additional 400w and run them together.
I have noticed how each of the plants grow in height representing the light they are catching (growing in pyramid shape, central plant taller than plant to the side of the light) I juggle them every 24 hours to keep a balance on height.
The next grow will be 20 - 24 plants now that I have popped my cherry.
The improvements I plan to make are and additional 400w light, 1 x TT100 on extract fan ducted with a t piece to extract the heat from each of the lights. (I may even get an additional TT100 inlet to compensate for the additional extraction, but will monitor this first. I have attached more pics for your pleasure. These are from 13:00 today.
