Since this thread was started 3 years ago more specific nutrients have become available, which you can see on our growing opener page.

http://www.chillisgalore.co.uk/growing_tips.html

These are just a few we've used and I know some people on here leave them to it and get a crop with just watering, feeding will give you an even better bigger crop and healthier plants. Chilli Focus is applied throughout the life just altering the strength as it blooms, Bat Guano can be applied as a top dressing and then will filter thro with watering.

Using Bat guano and Chilli Focus for the compost potted plants, Growth Technology Optimum Grow/Bloom 2 part nutes for the hydro plants, formulex for seedlings.

Out of interest what have people found the most beneficial pH range to be for their chillies? Mine in hydro are around 6-6.5 typically but I was interested to see Ralph has his at 6.8. I don't bother checking or changing the pH of the compost plants - they get what they are given hehe and don't seem to mind too much!

We keep to the same sort of pH as you Ben normally around 6.2/6.3

cheers Wilf.

A further thought for people - I have read on sites like RHS (i know - generalists compared to us chilli-specialists hehe!) that temps should be ideally kept to below 30 degree C under glass - even given our pretty poor summers of late this is unrealistically low - even with doors open, 2 side vents and 4 roof vents my greenhouse is frequently upwards of 40/45 degrees. I get fruit but am wondering if I should be looking to reduce temps by some active means if fruit yields might be significantly higher at a lower temp? What are others' experience in this regard?

Cheers

The trouble is with those sort of temperatures is, dissolved oxygen gets lowered in the Nutrients so deprives the plants. The amount of oxygen that can be held by the water depends on the water temperature, salinity, and pressure. (colder water holds more oxygen). Well oxygenated water allows the roots to extract water and nutrients with much less energy. There isnt much can be done except try to lower the tank temperature with cool box ice packs or such like.

Also found this........

Oxygen isn't as prevalent in warm water as in cool water, so oxygen levels tend to be low -- about two to four parts per million (ppm) in high greenhouse temperatures, compared to eight to nine ppm in cool water.

Under hot weather in the greenhouse, the root zone is especially short on oxygen, because root respiration depletes oxygen in hydroponic solutions. Excessive watering can further depress oxygen levels because it makes growth media, such as rockwool or coconut fibre, less porous, blocking air. These factors all weaken plant disease defense systems, making them more susceptible to disease-causing microbes such as Fusarium and Pythium which cause root decay.

hi,ive just got a bottle of Verve Liquid Seaweed Plant Food from B&Q ,and was wondering if any others have used this product? also to what ratio,as im thinking the dosage recommended may be too strong for chillis.
