# Quick Answer: How many plants can you grow under 600 watt LED?

Contents

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.

## How much can a 600w LED yield?

A 600w HPS light can produce up to 150 to 300 grams in optimal growing environments, which is 0.5 grams per watt or less. LEDs, however, can produce as high as 1 to 1.5 grams per watt.

## How far should a 600 watt LED light be from plants?

LED distance from plants and LED wattage

Wattage Distance from top of plant (inches)
200-399 12-20″
400-599 20-27″
600-799 30-38″
800-999 32-42″

## How many plants will one LED light produce?

If you grow more plants than your grow light covers, you are going to have a disappointing harvest. Say, for example, your grow setup is a tent with a single LED lamp providing a 3′ x 3′ coverage area. You cannot grow more than nine average size plants in that space with that grow light.

## How much area does a 600 watt light cover?

A 600 watt will cover 6×6 feet, a 400 will cover 4×4 feet, a 250 will cover 3×3 feet and a 150 will cover 2×2 feet. Higher wattage lights will cost more to operate, you can estimate operating cost with our cost calculator. The next choice is the type of light. We have Sodium, Halide and Fluorescent.

## How many plants can you grow in a 4×2 tent?

If you keep your plants small, you can fit 8 or more of them in a 2 x 4 foot grow tent. If you let them grow to a “normal” size, you can get two in a 2 by 4 area.

## Does LED yield more than HPS?

LEDs are much the same. Though they’re generally more efficient than HPS (with some clocking 2.8 µmol/joule), some LEDs are less efficient than high-quality HPS fixtures, and they give you less light. … All too often, the µmol/joule rating on HPS products states the lamp efficiency, not the actual product efficiency.

## Can LED lights burn plants?

Myth #14: LED Lights Can’t Damage Plants

LED lights tend to produce less heat than older technology, and their light intensity is relatively low. This has lead to the conclusion that you can put plants as close to the lights as you want and you won’t burn them.

## How many watts LED Grow?

The average LED grow light draws about 32 watts to cover 1 sq ft for flowering. Compare this to a typical HID fixture which rings in at 40 watts per square foot (assuming a 5′ x 5′ area, or 25 sq ft coverage area). Using an HID in a 4′ x 4′ will bring the power coverage up to 62.5 watts per sq ft.

## 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 watts does a plant light need?

As a rule of thumb, aim for 20 to 40 watts per square foot. Divide the wattage of your bulb by 20 (such as 400 watts divided by 20 = 20), and then divide the wattage of your bulb by 40 (400 divided by 40 = 10).

## What is the best wattage for LED grow lights?

A good rule-of-thumb for LED grow lights is 32 watts of actual wattage per square foot of growing space for flowering medical or other large flowering plants.

## How many watts do I need for house plants?

Low-light plants should receive between 10 and 15 watts of fluorescent light per square foot of growing space. A single fluorescent tube such as a 2-foot 20-watt tube or a 4-foot 40-watt tube without any other light provides only enough light for plants in this category (Table 1).

## How far away should LED grow lights be from seedlings?

There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.

## How far should a 600W HPS be from seedlings?

Unlike LED grow lights, HPS lights produce more heat, so growers need to know how far to put HPS lights from plants. The HPS distance from seedlings should generally be between 10 and 14 inches from plants.

## How many plants can a 1000W LED light grow?

As such, it could provide solid coverage for up to 4 plants. Yield Lab 1000W HPS+MH Cool Hood Reflector Grow Light Kit (Price: \$239.95) — With a 1000w grow light, you’ll get 130,000 lumens from an HPS bulb and 110,000 lumens from an MH bulb. That’s sufficient to provide coverage for up to 6 plants.
