How to Start Growing with Your iHarvest

Starting your seedlings:

If you purchased a seedling starter kit at starting your seedlings will be easy.

Propagation Kit

  • Assemble the kit and place it on the heating mat
  • Place 1-3 seeds in each rapid rooter pod
  • Make sure the pods are nice and wet, but that water does not pool up in the kit
  • Watch your seedlings grow, and place them in the iHarvest when they’ve sprouted

If you didn’t purchase a seedling starter kit, don’t worry.  You can make your own kit by using Tupperware covered with plastic wrap that you poke a few holes in.  Or, you can use the paper towel method, which works like this…

  • Dampen your paper towel with water so that it is plenty moist, but not dripping everywhere.
  • Place your paper towel in the plastic zipper bag (the bag should be wet, but not pool up with water)
  • Place your seeds in the plastic bag, on top of the moist paper towel
  • Zip the plastic bag at least ¾ of the way shut
  • Place the bag in a warm spot, away from direct sunlight. Placing the plastic bag on your TV cable box or similarly warm (but not hot) surface works best
  • Open the bag daily to allow some fresh air to circulate around the seeds
  • Wait for your plants to sprout, and transfer them to the rapid rooter pods before placing them in the iHarvest

You can also grow by dropping 1-3 seeds in each of your rapid rooter pods, placing it in the net pot, and waiting for them to grow.  Your seedlings will start off a little slower (7-10 days), but you'll be growing in no time!

Managing your Nutrients and pH:

*Keep Nutrients and pH solutions away from children and pets.  Read the directions and warnings carefully.

Before placing your seedlings in the iHarvest, you will want to condition the water so that it provides your plants with the proper nutrient and pH balance.  When starting your seedlings, please do the following:

  • Fill your reservoir to be ~50% full by adding 5-7 gallons of water.  The max fill of the reservoir is the top of the filter, but it is good to leave some room to add more water later, if you mistakenly add to many nutrients during setup.
  • Using the small measuring spoon included in your bag of Maxigro, slowly add Maxigro nutrients to the reservoir.
  • Either stir the nutrients in the water, or wait for the pump to cycle water for about 10 minutes with the nutrients to ensure they dissolve well.
  • Make sure your EC meter is set to PPM, by hitting the shift button until the screen says PPM
  • Measure the PPM with the included EC/TDS sensor. You will want a PPM reading of above 600 and below 750 for your seedlings.  (Read here for more information about what to do as your plants get bigger).  When your PPM is between 600 and 750, it’s time to adjust your pH. 
  • Use General Hydroponics pH Up and pH Down solutions to manage your pH after adding nutrients. It’s best to use plastic gloves when handling pH solutions, but at least make sure that you wash your hands afterwards. 

pH Up and Down

  • Measure the pH with the included pH sensor. You will want your pH to be between 5.8 and 6.5.  If your pH is below 5.8, then add the pH Up solution.  If your pH is above 6.5, then add the pH Down solution.  A little bit of pH solution goes a long way, so you should not have to add more than a few tablespoons in most cases.
  • Either stir the pH solution in the water, or wait for the pump to cycle water for about 10 minutes with the pH solution to ensure they dissolve well.
  • When your pH is between 5.8 and 6.5, check your PPM reading again to ensure it remains between 600 and 800. If you add additional nutrients or water to manage your PPM, make sure to check your pH again.
  • Continue to check your Nutrient and pH levels on a daily basis to make sure they stabilize. Once they have stabilized, you will only need to check them once or twice a week.
