Has anyone ever used the product in the pic? Came across it today, but the info with it wasnt very clear. Called Vita Grow Water Conditioner. I realise superthrive is talked about on the site alot, however im still a little confused. These types of products arent good to use early are they? Or are they benificial in veg also? The instructions for them are very vague, and wondered if any experienced folks could chime in. Thanks.
