36 Watt Grow Light Bulb for Seedlings and Small Plants

This grow light is perfect for getting seedlings started, vegging small plants, or when the sun is not out and your plant needs supplemental lighting. Pairing this with our Mini Grow Kit is the perfect combo to grow an adorable desk plant that can yield up to an oz (28 grams). Our 75 watt Grow Light is more suitable for getting a substantial yield growing our Small or Medium (2 or 5 Gallon) Kits fully indoors. ALERT: When comparing this grow light to other grow lights, be sure to check the "actual wall wattage", not the "comparable wattage". How much power the light actually draws from the wall is a much better indicator of how bright it is.

2. Aim it close

Point it straight down at the plant, close but not touching. Raise it if leaves curl or look bleached.

3. Set a timer

A plug-in timer keeps the hours steady every day, and gives your plant a dark rest each night.

Grow Bulb Questions

Is a 36 watt grow light enough for seedlings?

Yes. It is made for starting seedlings and keeping small plants growing. For a single seedling tray, a bonsai or a small potted plant near a window, 36 watts is plenty of fill-in light.

Can I put a grow bulb in a regular lamp?

Yes. It is a screw-in bulb, and our photos show it in an ordinary desk lamp. Check that your lamp has a screw-in socket and is rated for a 36 watt bulb.

How close should the bulb be to my plants?

Close, but not touching. Start a few inches above the leaves and watch your plant. If it stretches toward the light, bring it a little closer. If leaves curl, bleach or look crispy, raise it.

How many hours a day should I run it?

Most seedlings and small plants do well with about 14 to 18 hours of light a day, plus a dark rest. A simple plug-in timer keeps it steady, so you do not have to remember.

Can I use it for bonsai and houseplants?

Yes. It is a handy fill-in light for bonsai, herbs and houseplants, especially on cloudy stretches and short winter days, or in a spot that does not get much direct sun.

Can I grow small cannabis plants with it?

Yes, small ones. It pairs with our Bonsai 1/2 Gallon kit on a desk. Sun first, this bulb to fill in. To grow a 2 or 5 Gallon kit fully indoors, our 75 Watt LED Grow Light is the better fit.

What does actual wall wattage mean?

It is the power a light really uses. Some lights list a bigger "comparable" number. The real draw is the better way to compare lights, and this bulb is rated at 36 watts.

Do I need a grow light if I have a sunny window?

Not always. A window with a few hours of direct sun is the best start. This bulb helps on cloudy stretches, short winter days, or in a spot without much direct sun.
