Building a 8×8×8 room in my basement and not sure what power requirements I will need. Will one 15amp breaker work for lighting and heat? The summer avg temperature is61°f and winter is 65°f.
Welcome to the forums and I see you live in MI what county? Shiawassee here… Got a few of us but to answer your question Depends on the lighting what are you planning on using? What other equipment are you using? Fans and all that good stuff
Welcome to the community if you’re planning on lighting up the whole 64 square feet.at Fifty watts per square foot you will definitely need more than one 15 amp breaker. Not counting exhaust fan . You may be planning on building a 8 by 8 room and using a 4x4 tent. Inside room.
First off I want to say welcome to the community But 2-3 20 amp breakers would’ve better it all depends on how much stuff you plan to have

Livingston, I guess I could use help on that. Plan is to grow 5-8 plants. I’m sure I will need heat seeing the temperature is on the cold side. If I use led lights, will that help. I could always run two breakers and be on the safe side. Just have to move stuff around once.

You could use LED’s which will help. You are in a cool climate so you have more options than a lot of folks. You could use MH/HPS or CMH or LEC technology as well although LED’s (high end anyway) are generally more efficient and cooler. Plus the first one is not expensive compared to other tech.
In conventional lighting you will likely need somewhere around 50 wall watts per square foot. High end LED’s can drop that down to as low as 25 watts per square foot. These are all factors to consider when setting up your grow space. But you would max out a 15 amp circuit just on the LED’s. Double that for other lights.

Thanks. I will run two.
I’m just dropping by to say welcome to ILGM, and good luck on your grow!

Welcome to the forum! 8x8 is pretty big space, you will need a lot of light if you plan to use most of it. The light will require a lot of power too. On top of normal operating current draw, you will also need to account for inrush current of ballasts/power supplies. That can limit the amount of light per circuit below how you would typically load them. I’m guessing you would want multiple larger circuits. Any idea what you plan on using for lights?
My 8×8×8 space is a little bit big for my needs. I figure 8 plants will take a 4×8 space that needs to be lighted. I would use the the rest as a work and equipment space. I am considering LED and most likely run 240V for efficiency. Looking into lighting options and power requirements now.
New guy see, but not new to electrical toys. How much power can you draw from a single 15A circuit for LED lights? I know that this is an apples to oranges comparison, but I have an old Aragon 4004 power amplifier. It was specifically designed by Dan D’Agostino, the guy who also founded Krell Audio, to get the most possible power from a standard 15A 120V wall socket. The thinking was that while many rich, anal retentive high end stereo cats pull dedicated amp power lines, most mere mortals can’t, so the amp was built to max out a single normal circuit. The amp will throw a peak transient output of 400 watts at 8 ohms speaker resistance (200 per channel or 400 per amp for that later mono block version) . What makes it kind of unique at the time is that it will do like the much more expensive amps that require a healthier circuit and double that power to a total 800 watts into a 4 ohm load. Unlike the pricey ones, it won’t quite go to 1600 at 2 ohms but more like1200. Point being you can pull well over 1000 out of a regular wall socket, but at lower resistance. How do these lights work? What kid of load do they present? Is that really a factor with these lights? Seems to me that the 15 A circuit would be the baseline because even in rooms wirth multiple 120v wall outlets, you are more often than not running all of those on a single breaker.
@jdm61 I personally wouldn’t put all of it on 1-15 amp Circuit if you have access to your panel I would run 20 amp breakers on 12-2 wire and make up 2-3 new plugs and 2 separate circuits
For how much power? In my case< i am am currently running an entire stereo system though two plugs on the same circuit with power conditioners. I doubt that I will ever have more than something like either two 260 watt or one 550-600 HLG setup, more likely the former in say a 4 x 4 tent. I was thinking about running those through the higher current amplifier outlets on my old early 90’s Adcom power conditioner and running the fan, etc though the lower current plugs normally used for front end gear. The back of the units says max wattage for the two amplifier outlets is 1500w combined or 750 per outlet. The entire max load for the other 5 plugs, 4 of which are two prong ungrounded, is 300W total. I would probably be most comfortable only using the grounded outlet for the big fan, so that says up to 2 lights and a fan running off the grouded outlets conditioner. I guess I could run little clip fans, but I a timer would have to run from another plug so it shut down the power conditioner.
Then run it and see if it pops the breaker I always want my stuff on it own circuit
The air conditions in an indoor nursery tremendously affect the quality and amount of the completed harvest. Cultivators of all aptitude levels are consistently attempting to ace the unobtrusive ecological elements that can have a huge effect in growth and yield throughout a vegetation’s cycle.
When examining the environmental states of an indoor nursery, individuals are regularly alluding to moistness and temperature. Despite the fact that dampness is a significant angle, this article will concentrate on temperature, which assumes a fundamental job in the manner a plant can process light and admission water and supplements.
Temperature influences a plant’s capacity to photosynthesize, and it likewise assumes a key job in seed germination and foods grown from the ground improvement. On the off chance that temperatures fall outside the ideal range, the nursery turns out to be less productive. After some time, these wasteful aspects can prompt littler, lower-quality yields.
