Ok Ive decided to put up my GrowRoom spec's and maybe this will help on getting some more accurate answers (still nice one to CGI::its just I probably did nt explain exactly what Im needing to find out but your comment about chilling out abit on the nutrient level but still moniter them has calmed my thoughts alittle.

I have most things in my head straight, but the issues of when and how often to change reservior and how often to feed my plants on this dripper system, as with Hydro where you can in practice leave the Flood Drippers going non stop if you like, feeding plants in soil has to be a different watering schedule, I know of a few obvious ways of checking but if like me you want to maybe leave things alone for a while at a time if not convienient to check daily, things like this will be essential to know. I have heard times varying from 1x 15 minute daily feed to 4x 20 minute feeds per day so if anyone could give me some slighty more accurate watering shedules for Veg/Flowering on a Soil/Dripper recirculating system I'd love to hear from you. Thanks in advance.

Wilma 4 will be used for "Mothers", Wilma 16 for Veg/Flowering
Both have their own reserviors respectivly Wilma 16-250 Litre, Wilma 4-50 Litres using just Base Nutrients and assuming that the P.H is stable and plants happy, do I let the reservoir run till real low to top it up, or change as part of a weekly/fortnightly routine? E.Z S.K
SuperKellus Reviewed by SuperKellus on . Hydro Kit & Organic Medium I was wondering can you grow Hydroponically in soil and if so do most Hydro rules apply? I just bought what I thought was a Hydro set up (Wilma 16), but my preference to grow organically means I want to use soil, so am I growing Hydroponically? Seems to me the only difference is the dippers or the flood-drippers which you water the plants with, as this will be my first grow Im learning alot still and cant wait to get going but sometimes feel like my heads going to explode when I try to work out Rating: 5
