hello mello thanks for your input. im actually aware of all the things you mentioned so im going to try and rephrase my query with hopefully more clarity. I was trying to ascertain that if all variables being the same, airflow ambient temp thermal resistance etc; if i use a qb running at 75...

or say attaching a SST X Heatsink on top of the Predrilled Heatsink for QB304 Quantum Boards.

im in a tropical environment and wasnt planning on using a tent but a corner of an open room. maybe its overkill but i wanted something that can handle worst case scenario of upto 40C. would stacking two of your heatsinks above a single board make any difference? thank you.

if a larger heat sink is used will it be more effective running the same config at higher ambients? for example if two sinks were layered for each board. sorry if this is an ignorant thermodynamics question.

at what ambient temperature? Any idea how much does the heat sink weighs?

Hi are these heat sinks for passive or active cooling if running each panel at 75 W

starting an indoor grow for the first time. From my research Ive gathered i need to monitor soil ph, air humidity and temperature. CO2 measurements is something i can forgo for the first few rounds. Am I missing out on any other essential I need to measure? In terms of price sensitivity and...

Hi, when did the new samsung lm 561c diodes that you are using for this project first come out?

The best parts? These plants pull up to two pounds each, take up less than 6 sq ft of floor space and I grow them with 900W or less. Im sold on the donkeys dick. Full cycle growing is totally up my alley. Ive been lurking on and off riu for 6 months figuring how to best get started. Im...

mind blown twice in an hour i am. QUOTE="ttystikk, post: 13198883, member: 324297"]Sonic Screwdriver, only 43 days and already stooooopid frosty. Pic in the dark to give some idea;

hi ttystikk im a curious non pro. i've put on my diapers. Can you please send me a link to your friend steve's work so I can have my mind blown. Or any other link so I can get up to speed with what a quantum board in this context is even supposed to be. thank you in advance.

thanks for all the input everybody. I want to run a 5 cob setup. If i aim for one cob/sqft will I see a significant difference in yield if run them at 1050 A as opposed to 1400A.

hi, please do me a solid. I know its been mentioned on this thread earlier that CB is the best bin for the cx3590 Im a total noob with led just getting my feet wet. maybe the info still stands but from what i seem to glean today after going through crees datasheet is that BD is a better bin than...
