What is ghvi?
The greenhouse vegetable information presented in this web site has all been used by growers and is proven in practice by growers. The information provided is both practical and based on scientifically correct principles. It should have immediate value to growers in NZ and to other growers in any country, with adaptations for local climates and conditions. Much of the information could be of interest and value to growers anywhere. All information items are dated, and where appropriate references to other literature is included.
Consulting services are still available to anyone in New Zealand and Australia or anywhere by email. All of the information available and some of the services can be provided via the internet to clients anywhere. If you are interested or require more information on consulting services please send an email.

Fees and Charges
My time based fees are $NZ100 per hour or a daily charge fee of $NZ500. These fees do not include goods and service tax (GST) which has to be added to charges for NZ based clients, GST is not payable by overseas clients.
Email and Internet -Prospective clients are welcome to send requests for information and advice by email. When I receive an enquiry I will draft a reply and then email you with the cost of the reply and a bill to paid via PayPal. If you are happy with the fee,and pay the account to Paypal, then the reply will be emailed to you.
Visiting and on site consultations may be necessary for major projects, either as a single initial visit followed by ongoing advice over the internet, or sometimes as a series of visits over several months or years. Visiting is expensive as the client(s) is charged for all my travel costs plus a fee for the time spent with client, and fees for time spent in my office later on preparing reports. There is no charge for travel time. Clients in Australia and in New Zealand have found visits and consultations worth the high cost. It is sometimes possible to combine visits to more than one client in a single itinerary thus reducing costs per client. Quotes for visits will be provided before any travel is commenced.
