Not if the AC in his house is running. It should cool the air around the tent still.

Ok 4x8 in that case 6 legs. 2x4 might work. But as mentioned by other people 2x6 is better. Honestly I'd even use 2x8. If you want to roll it around you should cross brace and. A 2x8 will give way more area to fasten the legs and help keep the legs from flexing while rolling.

4 legs. A 2x4 table full of plants still won't weight shit. Check out Home Depot concrete or mortar mixing tubs. They are like $25 and are 2x3 or something close to that

CRI is color rendering index which is a number out of 100 for how true colours appear compared to how they would appear under 100CRI (sunlight). Some growers believe the higher CRI is better or easier to grow under I don't know if that's ever been proven scientifically. colour temperature K is...

Those are 80CRI only. But ya I used the 3500K strips and been running 2 years now. They will grow fine dank on their own.

Dimmer is a component you add to the driver. And the driver needs to have dimming leads.

Samsung are just popular because the LM301b is a very efficient diode. But you can make many different strip options equally or more efficient than many fixtures produced with samsung diodes. It depends how much drive current you drive the LEDs with relative to their nominal current. I think...

I think Meiji or Kingbrite can't remember which use the SK bin for the LM281B. So I just use that bin or whatever bin they claim to check their posted efficacy numbers based on diodes counts and compare to the Samsung calculator for the claimed led binning. But the numbers almost never match and...

Where do you live the cheapest option would depend on what drivers you have access to. Maybe two meanwell 240W drivers would suit best. They are around $40-50 and you can probably find them a little cheaper on eBay or something...

Just use the bridgelux strips at nominal amperage (0.7a or 700ma) and you won't need much heat sink. A simple u channel with no powder will be more than enough.

This is the stuff inside of ice packs. I could be wrong. But from my understanding of thermodynamics this will not work unless you put your light in the freezer/fridge everytime before use. basically this material has a very high heat capacity so it can absorb a lot of heat, however since it's...

https://www.rollitup.org/t/bridgelux-eb-gen-2-thermals.957453/ ebgen 3 slims at nominal are fine without a heatsink. But I recommend some aluminum or some heatsink to make the strip stronger. Because they are pretty fragile especially 4ft.

The type of diode you can buy will depend on the solder foot print of the mpcb you make/buy. If you can do 3030 foot print that fits lm301b as well Osram mono diodes (660nm and 730nm etc etc). Depending on your MPCBs circuit be careful with balancing voltage on different LED strings

I would not downgrade the wiring to less capacity than the plug you are going into. It's bad practice and probably illegal. Going to a smaller wire than the capacity of the dryer plug means if something goes wrong and the connected devices can draw more amperage than the wiring can withstand...

Whats the relation to metals? I am a welder just curious because it also started for me when I started to do heavy hours welding.

I don't get it anymore. But my habits are much improved from before.

If you've been pretty hard on the weed intake especially weed concentrates that constant nausea could be Cannabinoid hyperemesis syndrome i got this before when I was crushing shatter pens like no tomorrow. One way to check when you feel nauseas take a hot shower or bath. If the nausea is...

Do you exercise? If not you could start there. Exercise is a great mood elevator as you engage your natural endocannabinoid system. i really enjoy hot yoga and lifting weights and jiu jitsu. But a hard run which is free is Just as good or better for your mental health. also finding a job or...

I would like to try this.

Most LEDs for sale do both 120/240 but it actually depends on the driver. I have some meanwell drivers that are 180V - 480V. So it depends on the light. But in most cases if it does 120 it does 240 as well.
