Hey man, I am new to growing to but have had good results so far with canna terra. You will have to get it from ebay or a hydro store. All i mix in it is perlite about 15% i guess. Plant it straight into the soil, which i water in fully, 3 days before planting the seeds. Then a little water to settle the soil around the little hole you made, cover it to keep it humid till germination. Then till its about 5-6 days old the only liquid it gets is a water and rhizo mixture (1.5mls per litre) with a spray bottle. PH this, it reads ridiculously high and can only be used for two days max, then you need a new mix. **i also use rhizo in the watering in of the pot before the seed is planted**, same strength. Dont water it with any more than a surface wetting in this time with the spray bottle, the pot contains enough water to last at least the first 5-6 days, 24 litre pots i use , but the temp during the day where i live is 30*C and gets down to 22*C at night, so it does dry out quickly here, you could leave it longer in cooler climates. The soil will look dry but, if you put your finger in and can feel ANY moisture in the soil up to at least 15cm down leave it another day. It sounds sadistic but it works a dream. Also ph everything that goes in, if you use canna terra, to 5.8 in veg, including seedling stage and the pre water of the pot. Hope this helps, it works for me anyway, have a good one
