Hey man, which CMH's would you recommend for a beginner who wants to start small and expand later without replacing too much gear? What do you think about air cooled cmh? Separate 315's vs double 315's in a 630? Rather not have to run any AC and just use good ventilation. Any tips would really be appreciated. Hard to find people with actual hands on experience vs guys who talk a lot of bs. Thank you!!!

Demon, can you tell me where you are ordering your T9 bulbs from now a days? Having trouble sourcing the T9 930/940s. If you have a link I'd really appreciate it.

I was looking at this one but unsure of the sites reputability: https://www.lighting-spot.com/cdm-t9-elite-315w-930-e.html

Demon can you link me to your thread about making the liquid pens??

is it possible to change the name of my thread in the grow journal?
