Do you need a ballast for LED grow lights?

Can you use a grow light without a ballast?

Hence, a grow light ballast helps control how much electricity your bulb receives so it can operate the way it needs to. If there’s no ballast, your bulb could either produce too much electricity or blow up. Any traditional tube fluorescent bulb and high-intensity bulbs require a ballast.

What does a grow light ballast do?

Grow light ballasts power high intensity grow bulbs and lamps by regulating the voltage to a high intensity discharge (HID) light or compact fluorescent light. Some ballasts power specific bulb types while others are “switchable,” capable of powering both HPS and MH bulbs.

What size LED grow light do I need?

Standard advice says you should aim for 32-50 watts per square foot of grow space. More like 25 watts if your grow space is a dedicated veg tent. So if you were working with a 3′ x 3′ space, you’d theoretically want an LED light with a power draw somewhere between 225 watts (vegetative) and 450 watts (flowering).

How many plants can a 600w LED grow?

2 month plants should give about 40g per plant, so with about 9 you’ll be able to easily fill a square meter and get up to 400g per 600w light. 3 month autoflowering plants grow much bigger, however, so you should only plant 4 per 600w light.

Are LED grow lights different from regular LED lights?

What’s the difference between LED lights and LED grow lights? Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.

Where do you put the ballast in a grow tent?

If possible, the ballast should be placed outside of the grow tent. Ballasts, particularly magnetic core and coil types, produce heat which is usually best kept out of the tent if possible. Wherever it is located, make sure it is placed on a flat, firm surface such as a table, or hung on a wall.

Do grow light ballast get hot?

There are basically two types of ballasts: magnetic ballasts and electronic ballasts. … These components get hot, too, but because of their small size and design, most- if not all- electronic ballasts have internal fans to keep them cool when operating (just like a computer).
