I like that light. I wanted to do SOG but my plants rooted at different times so i had to use a screen. Nice grow man plants are healthy, nugs look nice, i would say you cashed out bro

Questions:

Did you have any heat problems with just computer fans?

What were your lights-on and lights-off temps?

Hello bro,

PC fans are all right, its cca: 8 x 75 = 600 m^3/h together...I used just half voltage (6V -> about 200 m^3/h I guess) and temps were all right all time. I did not measure it exactly.

Nice yield man

I'll probably get half that from my 400 LOL

THX friens

I'll probably get half that from my 400 LOL

Dynamic illumination is very usefull to expand your yield. Lightrail or another way of "light moving" in your box help you to effectively illuminate larger area with the same lumens output and harvest more buds.


Newxt round I'll try Bubblegum from Serious Seed "crystal coverd bud". Continue about a month. My wish is to get 500g dry, and I dont think that's impossible...

 

[m3th0ds909]

yea man definitely possible... my cab is just half the size of your area lol.

maybe try using a coco medium.

How do you keep it all cool. I grew 4 crops with my 400w mh/hps but got small harvest mostly due to heat stress I believe. Averaged only 100-150 grams total?

Hi, what area do you have? With dynamic reflector and 400w its possible to illuminate 1.2m x 1.2m. I use 8 x PC fan (12 x 12) cm and only on 6V (not 12V full) and temp is all right.
