Why should you have a grow box?

View growboxes

Other than the “Do you really just grow ‘strawberries’ in your grow box?”  question.  The most common question I have gotten is why exactly do I have a grow box.  Hopefully I will be able to answer this question below, as for the first question the answer is yes (without the fingerquotes)

Necessity:  I am cheap and don’t want to buy all my plants from local nursery or garden center, but do not have a good location inside my house to grow seedlings with a normal table/shelf light setup.  I definitely do not have the space to setup a greenhouse in the backyard.  This unfortunately forces me to do my growing in my cold windowless garage.  Using a grow box allows me to maintain a safe temperature for my plants no matter what the conditions are outside.

Control:  I have nearly complete control of the conditions inside the grow box.  I can provide my plants with the perfect temperature, humidity, lights (intensity and wavelength as well as day/night simulation) and even can simulate a slight breeze using a small fan if desired.  This gives me many advantages which I would not have even if I could grow indoors.  One example of this is growing peppers, which can be fairly difficult in our climate but with some modifications settings in the grow box can create the perfect conditions for it.

Saving Money:  Given my options such as the $20 PC Grow Box and my $6 Christmas Light LED Grow Box the cost of entry is pretty low.  You do have the expense of lighting the thing but given the 48 watts required for the PC Grow Box and 10 watts of the Christmas Light LED Grow Box even those maintenance costs are reasonable.

Portability:  All three of my grow boxes (PC Grow Box, LED Grow Box, Computerized Grow Box) all have a single plug that goes into the outlet and can literally be picked up and moved to another location if needed (try doing that with your greenhouse)

Scalability: Need more space in your grow box?  As little as $6 can get you a new one, or $10 worth of lumber can double the size of your existing one (assuming your old lighting can support the space)  You are limited to what your creativity can imagine.

Fun:  Call me crazy, but I like the idea of tricking my strawberries that it is a nice spring day and get them to start blooming and producing fruit.  If all goes well I can move the plants outside during the real spring and get even more harvest while freeing up some space for more plants.

Cheap Vegetable Seeds

Cheap vegetable seeds

Looking at my web logs I have seen the query for “cheap vegetable seeds” a few times so figured would be good to help people find what they are looking for. Being The Cheap Vegetable Gardener, I can do better than “Cheap vegetable seeds” how about some “free vegetable seeds” as well.

Cheap Vegetable Seeds

  • Buy online — You can find a much greater selection and some great prices compared to your local home and garden center. For example right now:
    • One of my favorites is Burpee Seeds, they have been around since 1876 and definitely know their stuff. The actually have a seed sale going on now where you get $15 off on order of $75 (just use code AFFB4A35) expires on 1/15.
    • The name is not too exciting but Generic Seeds offers no thrills packaging with quality seeds and very reasonable prices and if you spend $20 or more shipping is on them.
  • Local seed swaps — Many groups will have annual seed swaps where you enter for a small fee and/or a packet or two of seeds and you leave with much more than you came with.
  • Free Vegetable Seeds (pretty much)

    • Ask your neighbors — Notice your neighbor is a gardener, check if they want to go in on a seed order and share unless you really need 200 carrots this year.
    • Harvest your own seeds — If your plants bolt to seed early this year, don’t pull them out let them create some seeds for next season. Notice your neighbor has some seeding plants, ask if you can get some (important part is to ask though)
    • Get seeds from the grocery store — Before putting those vegetables in the compost bin, set the seeds aside to let them dry and you got some free seeds. Though a word of warning many vegetables are hybrids and may be infertile or not produce the same quality of product but hey its free.
    • Check your spice rack — Many cases you can plant seeds from your spice rack. Some ideas, mustard seed, dill seed, coriander, poppy seed, celery seed. If your spice rack is lacking you can pay a few cents buy a teaspoon of organic spices in bulk, last time I bought dill seeds got about 100 seeds for $0.05.
    • Seed swap web sites — Below I have listed a few links where you can share seeds with others. This is a great way to find some heirloom seeds you might not be able to find in stores/seed catalogs. In many cases people will offer seeds for free by just sending a SASE (Self Addressed Stamped Envelope) Just remember to pay it forward when you come into a plethora of seeds yourself.

    LED Christmas light grow box

    I noticed some of my daisies were getting a little leggy so added 60 more LEDs (red) to my LED grow box.  This time I was a little less calculated about positioning but still fee like I got a decent pattern going.  I also decreased the drill size and didn’t even need to use the hot glue gun.

    As you can see from the pictures below the plants (cucumbers, onions, cilantro, purple coneflowers) have a dark green complexion and are less leggy compared to the results I would get from my window sill.  The cucumber plants after two weeks have grown up enough to move into the LEDs grow box’s big brother.

    Using used coffee grounds in your garden/compost

    coffee_posterI have wanted to leverage used coffee grounds in my garden/compost but not being a coffee drinker myself I never seemed to be able to have the right timing to find any at local coffee shops.  Recently a colleague taunted me with a picture from his cell phone of a few bags in the coffee shop in our cafeteria at work and my quest began.

    After just two days I have accumulated 40 lbs of coffee grounds, now how can I use this stuff in my garden?

    • Throw it in your compost: Coffee grounds are 1.45% nitrogen and contain calcium and magnesium to add some trace minerals you may not get from your other organic material.  Coffee grounds are a green material (I know coffee is brown, but same idea as grass clippings) so you should add with at least equal amounts of brown material (leaves) but if you are like me my browns are way to high already.
    • Add it directly to your garden: I have seen some arguments that coffee grounds are acidic, but others claim it loses most (or all) of its acidity during the brewing process.  Due to my natural curiosity I need to know the answer.  So the answer is, it has an average pH of 6.9 so for all intents and purposes, it is neutral. Though if you are really tired and forget to brew it, it will be somewhat acidic.
    • Fertilizer: Sometimes your plants need a little boost in the morning as well.  Simply add a couple cups of coffee grounds to a bucket of water and let it seep for 24 hours and apply to plant in the same way you would compost tea.  Using gardener terms I can’t think of any better name for this as “coffee tea”  If you are busy/lazy you also can use it as a side dressing on top of your soil and let the rain seep it for you.
    • Annoy your pests to stay out of your garden: It has been said that coffee grounds can deter cats from using your garden as their own personal commode.  There are also reports that it can deter slugs as well.  I am not sure if it is the abrasive soil effect on their sensitive underside or just the cruel reality that with their slow pace they can’t do anything with the caffeine rush they get.  Coffee grounds may annoy ants to convince them to move their home elsewhere.
    • Feed your worms: To worms this stuff is like ice cream, if you listen carefully you may hear them cheer your name when you add a handful to your worm bin when your greens from the kitchen may be a little lacking.

    According to Starbucks brochure I picked up on my last visit, you should use the coffee grounds within 3 weeks to get the most nutrient value, though if you are composting I am sure you can start out the process in the bag if you really want to.  Given that 16.34 billion pounds of coffee is produced each year there is plenty for you to save from ending up in a landfill.  This is a great way to help the environment while also adding value to your garden without affecting your pocketbook.

    Christmas light LED grow box – Update #1

    IMG_1543

    I have been pretty impressed with the results of the Christmas lights LED grow box so far. I did have some preconceptions that I may need to double the lights or upgrade the LEDs, but so far the plants look healthy without white leggy stems, though still need to wait until the true leaves come in. As you can see in the picture above I have quite a selection of pots reused from previous years. The one exception are the newspaper pots which I discovered last year and am definitely a fan of.  You can also see from the gross white stuff that my grow box probably could use a fan or at least prop a corner open.

    Here is a picture of one of the cucumber plants up close.

    My experiment is being conducted in the LED grow box so for its update, looks like is in the lead but hard to say with just germination occurring.

    Using WonderSoil for seed starting

    I had great results using coconut coir last growing season it was great to work with, retained water great for young seedlings, and was economically priced.  The only challenge was actually finding some to use this year.  No luck in local stores, last year I only could find a single block in one hardware store.  Online there are plenty of locations that sell them, but unless you have a need for a couple metric tons, the cost of shipping can be more than the the product itself.


    Finally, I found a solution to my problem WonderSoil  Their main product line consists primarily of the same core component but they sell it in many different convenient sizes for various uses.  One great feature of the product is it expands up to 12 times its original size.  For someone like myself that does not have the space to store bags of peat/potting mix around my already full garage this is a great feature.  You can check out all of their products but the ones that felt matched my growing needs were the following:

    • Shake, Water, and Plant — 1/2 inch mini wafers that can be added to any of your pots.  In my case I underestimated the expansion of these little things and made a little mess and it overflowed on my table (apparently 3 was the magic number not 4)
    • The Tube — There are larger wafers made specifically for 4 inch pots, in my case this would be newspaper pots
    • Reground Wafers — This is basically a loose version available in 2 or 5 lb bags.  This is a more economical option which I will plan on using when doing larger seed trays.

    For Christmas I got indoor seed starting kit which came with pots/seeds/peat pellets.  I decided this would be a great opportunity to do a little side by side comparison.  From the start I was WonderSoil seemed like the obvious winner.  After adding a little water, it fully expanded in just a few seconds and was fluffy and ready for me to drop a seed in, the peat was a swampy mess.

    Peat pellets Left, WonderSoil Right

    After a few minutes and fluffing with a fork the peat was ready to planting.  I put cucumber seeds in both peat and WonderSoil pots and I will provide some updates on how things progress on my little experiment.

    After the WonderSoil had some time to settle in my cheap LED grow box I did see some strange formations appear in the soil.

    I little concerned I went back to their product and I believe this is their “water saving polymers” in action which I would assume is some sort of gel crystal which is supposed to save up to 50% water.  They also boast about use of worm castings which I am definitely a fan of as well as addition of a balance of various micronutrients.

    I will have to wait and see if the product produces as well as it claims, but I must say I am definitely impressed at this point and have high hopes for WonderSoil for this years seedlings.
