hi all I got this sample of Botanicare "Guardian My - Mycorrhizal rhizosphere inoculant" and im not completely sure how to use it. seems like all the instructions are for hand watering or something it says: Directions for first application: rooted seedlings and cuttings: drench root zone with 4ml of Botanicare "Guardian My - Mycorrhizal rhizosphere inoculant"with 40ml of water per plant site or 100ml per liter of water per 25 plants to achieve 50 propagules per plant site(what???) Directions for maintenance: perform follow up treatment at above dosage 2 weeks after 1st application. so...... what do i do if i use rockwool in a flood and drain system and what should i use it on?clones?seedling?vegging plants?flowering plants? at what strengh for the flood and drain? thanx
