  1. How to Build a Cheap Grow-Light Box for Seed Starting – The Rusted Garden

    You can build a grow-light box cheaply. This project cost $27 for the first
    box and only $17 for the second box. It can be made with just a knife. Very
    simple but effective construction. It is great for starting vegetable seeds
    and growing vegetable transplants for your garden.

  2. MacGyver! LOL Pretty cool project Gary. How’s the temp buildup in the box?
    I understand the bulbs are relatively cool but mine had heat buildup issues
    so I had to prop the lid. The brightness in that box is insane. I’m betting
    the seedlings are going to be loving it in there. :)

    Very good ideas, Gary. Thanks for sharing.

  4. Have you considered aluminun tape as opposed to duct tape? That would
    insure that everything was reflective.

  5. Another great project by +Gary Pilarchik. This coming spring I’m going to
    try several methods for seed starting. I might give this grow light box a
    try. Thanks for your details.

    Great idea. I might try this and add something at the bottom to get the
    heating pad in it. You’re very creative!

    This fits my bill exactly. Thanks, Gary.

  8. Very nice and easy build +Gary Pilarchik! I really liked how your itemized
    everything at the beginning of the video. Thanks!

    Nice gardening tip and obviously very easy and economical to set up…
    Thanks for the video :) 

  11. Hey I have a question. Do you need a grow box if you have a sun room that
    gets sunlight every hour the sun is out except sunrise and sunset? Also its
    winter so it tends to be 50-60 degrees there during the day and maybe 45 at

    Hi Gary, would a 27/28 gallon Rubbermaid tote be good if I will use the
    200W CFL, I figured if I doubled the wattage, the size of the tote should
    be doubled as well.

  13. Do you use this or its just a novelty like the self watering bucket you’d

  14. Do you encounter problems with excessive heat in your grow light box?

    +Gary Pilarchik I have never done grow lights because I just didn’t want to
    take the time to set up a whole system. But you made it look so easy and I
    even have all the materials already that you used in this video! Really
    nice, quick and easy set up. Maybe I”ll make one this weekend and post a
    video! And give you credit, of course!

    Great tip, Gary!

    Best wishes,

  17. HELP! Please give us a link to where you got those 100W 5000K bulbs. The
    cheapest ones I can find are $16 EACH on Amazon.

  18. Like the idea- but I would be opening the box all the time…..

  19. How to make a grow-light box cheaply. No tools just a knife. Great for
    seedlings and transplants. You can make this!

    Hi Gary hoping you can show the bigger box construction and the flatter
    ones for seed starts. Am not that handy thats why your videos would help.
    Hoping it comes soon for some winter projects. 

  21. What a good idea!!! My cats and birds can’t get to the seedlings his way.
    Last year my Kakarikies ate al the young pepper plants and the cats like to
    (stealthy) kick them from the windowsill. So next year my garden will be
    full of pepperplants again. Thank you!

  22. Great plan I will get mine done tomorrow a the weather is only warming up
    here in Ireland and no tomato plants growing yet thanks

  23. Gary I purchased all these material as well. My bulb is a Feit Electric
    ESL40TN/D 40-Watt Compact Fluorescent High-Wattage Bulb Daylight from
    Amazon. I also purchased a light Bulb splitter to add two light bulbs.
    Looking at your setup I think maybe two lights bulbs might be too much. I
    was going to add a second fluorescent bulb, less K, which I have a bunch
    around the house since I changed all light in the house to LED. The light
    bulbs pull less watts than the lamp is rated at so I feel safe using two.
    I wanted to ask your opinion, do you think my two lights are too much? The
    second light is a 23W 2700k. BTW thanks for the lid idea I was still in the
    brain storm stage of how to cut it to install the lamp. My first idea was
    to simply use a 5 Gallon bucket since I won’t grow that many. Still might
    go that way and just clamp the lamp to the side and use Tin Foil on the
    inside and top it off with reflective Mylar. The Mylar sheet is from last

  24. Very nice box however there is one flaw in its construction. I see you
    line your box with aluminum foil. Foil has many angles (or will by the
    time you apply it) which reflect the light causing hot spots that can burn
    your sensitive seedlings. Mylar is a much better alternative, or even non
    glossy poster board if your trying to keep it cheep. I would also install
    some sort of ventilation to simulate a breeze to strengthen the stems. This
    also allows the air to be recycled which is very important. I use a 12
    volt computer fan ($2 at radioshack) powered by an old computer power

  25. a white surface will reflect more light than aluminum foil.
