Make your first grow in soil or a semi-soilless mix. Don't use expense seeds. Use seeds from a bag you bought. Start small - only 8 - 12 plants.
3 gallon pot - mix up you growing medium from the following guidelines :
(1) part compost (1) part peat moss (1) part vermiculite or pertilite (1) part potting soil (without fertilizer in it - don't buy Walmart's super cheap potting soil - it blows)
.
Start your seeds in a couple of wet paper towels, in a warm dark place. Once, they germinate and the root is sticking out. Plant it, just deep enough, to cover the root, leave the top uncovered.
.
Listen very carefully - The top two mistakes made are - OVERWATERING & OVERFERTILIZING.
.
Mix up some very weak fertilizer - I suggest Peter's brand - it's cheap, has micro-nutrients & works well. It comes as a 20-20-20 NPK mix, just cut the mixing dose down to a quarter or less of what is suggested. That will make a NPK of 5-5-5 or under.
.
Pour in one quart of this weak fertilizer for every gallon of soil you have in your pot - no more.
.
Now, leave Mary alone. Let her do her thing. In one week, water using only plain water - same guidelines - one quart per gallon of soil in your pot.
.
Stay on this schedule. Water once every week, fertilize once every two weeks - no more.
.
Each time you fertilize, increase your mix just a little. Don't go above 10-10-10.
.
When your plants start to pre-flower (stop growing & start showing sex) switch to a cheap - flowering fertilizer. It should have less Nitrogen and more Phosphorus & K (Potassium). The numbers will be like NPK 3-8-6 or 1-4-4 It does not have to be exact. Just more P & K, less N.
.
Read the threads suggested by the growers above & relax - Mary is a weed - in nature she grows just fine without our help. She does not require perfect conditions - Just a decent source of light (the sun or at least 40 watts of light (don't use regular light bulbs) per square foot - Compact Floro's, or Floro' shop lights or a small MH or HPS grow light), some water, some nutrients & a medium to spread her roots in.
.
She's a weed - this is not rocket science - don't sweat the small stuff. It's pretty easy - just don't kill her with kindness - overwatering & overfertilizing.
