light will damage the roots.not sure of the exact science behind but it does. you could use the clear pots if you found another pot to put them in.I have started plants in clear party cup & kept it in a red cup to block the light but still be able to see root growth.

agreed. go w/ the proper outlets. you could wire a 110 outlet for 220 but all it takes is 1 stoner moment to try to plug a fan into the outlet......

no you need a transformer see this post https://www.rollitup.org/grow-room-design-setup/385722-about-pc-fans.html

OK so ASSUMING the heater wire is 12 gauge,you can have 40 amps of 110 availible near your room.(+ whatever is already in the room) the 3 600 watt ballasts will use 1/2 leaving 20 amps for fans,pumps, ect, this might be enough to add 1 more 600 light in the future but if you expect to add more...

not on candles but yrs ago I found a formula to determine how much co2 was made by burning rubbing alchohol. at the time I had a 4x4x6 closet running so I did the numbers and came up w/ needing less than 3 oz per 12 hr day.if I turned my air over once per hour.(needed to vent the heat) I got a...

do you have a crawl space under? it would be easier. outdoors needs special wire & will look like hell. what wire goes to the heater?

thats a 20 amp 220 circuit, so 3 600 watt light will draw about 10 amps romex or you can also buy extension cord by the foot at most home depot type stores. you can use the existing wire IF it has 3 wires plus a ground. a 220 heater doesn't need a neutral so it may have been run w/ 12/2...

the outer jacket of the wire should be labeled what size it is in gauge so it will say something like 10/3 or12/2 romex. that will be important & hard to tell from a photo.

a ballast is made of 3 parts, a transformer,capacitor, & ignitor. any of the 3 could have failed but the transformer itself is least likely. if its more than 5 yrs old,I would just buy the entire kit & be done w/ it. most kits I have seen are already wired & all you need to do is attach the...

if you are asking this vague a question,I assume you have little or no experience w/ electric work so I would keep it simple.instead of a subpanel,you can run a couple dedicated lines. for 3000 watts of light,I would run a 20 amp, 220 line w/ a water heater type timer & a 20 amp 110 breaker for...

google high output leds to find them I looked into building 1 when they first came out. did the research,priced them out & found that it would only save about $20 instead of buying a UFO from ebay. factor in a couple hours of time to solder all the connections........

OK you want cheap? try this http://www.co2meter.com/collections/co2-sensors/products/k-22-oc-co2-sensor-module $100. it has a built in output that will trigger your regulator when CO2 drops below 800 ppm and off at 1000 ppm. not ideal but if you place it up high where the CO2 levels are...

N.America or Europe?

that breakerbox http://www.homedepot.com/h_d1/N-5yc1v/R-100557051/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 is a bit overkill but for the price I would consider it. I would not try to "pigtail" to an existing breaker as it violates code & is unneeded. pick a heater you don't...

w/ no experience, you might be better off running a dedicated 20 amp 220 line to the room to feed the lights. it would be a lot easier DIY project than a subpanel (assuming your ballasts can run 220) you would need a 220 breaker that fits your current box, 12/3 romex, and a few single gang...

70 amps for what you need is overkill.you can easily run 2 600 watt lights off a 15 amp breaker or 3 on a 20 amp breaker. the breaker box you want will be something like this; http://www.homedepot.com/h_d1/N-5yc1v/R-100184775/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053 from the...

most CMHs need a HPS ballast to work

how about a book or 2 on growing.

if "it needs to be short like less than 3 feet tall", it sounds like you need an autoflower

i have had 2 of them.when checked, 1 was dead on the other showed vineger,OJ and amonia all around 6-7 to check yours,vineger should be around 2,OJ about 3,milk around 6,egg white about 8 and amonia over 10
