If you have a flexible budget, and want to ensure your rare & valuable seeds have the best possible start to life, check out this method below. Before we go any further, in all reality you can germinate seeds with nothing more than tap water and some paper towels. But if you are a perfectionist or somebody who refuses to cut corners, keep reading AND IF YOU THINK YOUR GERM METHOD IS BETTER, THATS GREAT, USE IT & DON'T BOTHER TO READ THIS. (i.e. Twista) Honestly, budget wise, these items are costly, but are worth every cent. If nothing else, at least stick with a Rapid Rooter tray, and get a dome to cover the top to maintain humidity. I use a HydroLogic brand RO filter, model "Stealth RO 200" , and with my tap water, it allows me ultra pure at zero TDS. one more thing... Seeds sprout without light in a wide margin of temps. Proper seed germination happens within 2 to 7 days, in safe temps. from 72 - 88 F. The nutrient trio, will give your roots explosive growth, unmatched in the total spectrum of beneficial supplemental food & root zone bacteria. I have compared this RR plug tray with friends results when compared with either a different brand of nutrients (in very small amounts of course), or either just plain RO water. Results move me...actually I critique and demand high (sometimes close to unobtainable) results for what I buy, & trust with my time. Time is money my friends. Hope you all have wonderful results with this recipe or ANY recipe that you like, & your plants like Happy growing my friends.... You will need: Rapid Rooter Natural Plant Starter 1 Liter of Reverse Osmosis water (000 ppm preferred) 1 ml of AN Liquid Piranha 1 ml of AN Liquid Tarantula 1 ml of AN liquid Voodoo Juice 1 small syringe to insure accuracy (DO NOT go over 1 ml) and gently yet thoroughly shake each nute container before mix. A plastic fork, great for breaking tongs off, perfect for gently pushing the seed in the hole, and pointing the taproot (pointy) side of the seed down. **Take a shotglass, and fill with RO water. Use this water from the shotglass, to suck up some fresh water into your syringe, to squeeze back out & cleanse the syringe in this manner, in between fills of each of the 3 Advanced Nute components in your recipe. One last note, these products are awesome stand alone, so if you must choice, IMO, priority wise, if I had to pick one of the three, it would Be Voodoo. For the bennies, if I had to choose, I would take Tarantula, over Piranha, but just barely, but if you ever get the chance to use the whole "cocktail", .... I'd be willing to bet you'll never go back Also graph paper or something to keep your seeds marked A plastic fork, great for breaking tongs off, perfect for gently pushing the seed in the whole, and pointing the taproot (pointy) side of the seed down. Also, set aside one of the cubes to use, to tear very small pieces. Use these to cover the hole & seed after the seed is in place in the cube, facing down. This keeps it locked and loaded with darkness, moisture, humidity, and temp control. It's by nature of the breathable substrate. You will want to keep your humidity dome on, and closed until your first set of seed leaves appear. Not the embryo leaves (cotyledons), but after you get a few sets of the distinct jagged real leaves showing, then its safe to vent the dome, or take it off. You can leave a cube out, to make it easy for a quick visual inspection of water level. The cubes are organic and have a perfect air to water ratio, so they don't need pre soaking, and there is really no worry of over watering. THIS SAME LIST AND METHOD WORKS FOR CLONING, EVERYTHING TREATED THE SAME. You don't have too, but add your favorite cloning gel like normal before you insert into plugs. Also make sure your plants have the appropriate T5 or similar florescent bulb ready after the seeds start to break ground, so they don't get too stretched. Like i said, this is more or less an expensive way to go, but if you already use Advanced Nutrients, you understand why. One more thing, if your able to measure that precise, even at 0.5 - 0.75 ml this method will show a markedly improved result over using only water.
