    CXA3070s for Growing Indoor Fruit and Vegetables

    Hanging the contact points, as I do in my picture, off the side of the raised surface doesn't mean they are "floating in thin air".....they're in contact with the sloped side of the sink. Is that still a problem? I don't see how....but am willing to understand if it is explained :)

    PS - I will also keep a diary of all the fruit weight that is picked from the plants.......am convinced higher DLI and more controlled conditions will produce heavier and healthier fruit.

    Zucchini fruit growing at an almost alarming rate (5mm thickness and 11mm length overnight!!!) .......I think I will get the first "meal" before day 35......which surely has to be a sign that the plants like the lights?! Some of the zucchini have been moved outside and the tomatoes will also...

    CXA3070s for Growing Indoor Fruit and Vegetables

    If you are driving CXA COBs at 1400mA, then you need to leave a 20cm gap between COB and canopy otherwise your umol/m2/s will exceed 1500. You won't bleach them (that happens around 18cm) but it means that the plant is receiving more light over 12 hours than midsummers day in Phoenix Arizona...

    CXA3070s for Growing Indoor Fruit and Vegetables

    Yes sir :) relativity requires both! If you want I'll take some readings tomorrow and show you. Just finished up boring hundreds of holes into my 9 new 4 litre pots for the next stage of my zucchini growth. The feeling of accomplishment would be massive, if that didn't mean I had now 9 empty...

    All the PPFD statements are backed by actual testing with a PAR meter.... The Rest is opinion.

    CXA3070s for Growing Indoor Fruit and Vegetables

    @bicit well......um........."insert totally unscientific opinion here".......that's what! ;) Seriously though, the COB has a wide angle, but relatively poor light distribution on an even basis. The RP panel is very uniform in terms of PPFD across the size of the panel. This uniform...

    No, but will take a photo later tonight when it's off :) These kind of show the box that houses the 8 RB LEDs.....just imagine that the RP panel clips onto the front of the box

    What sort of product info are you after that isn't on their website? I use it as a diffuse light source that isn't as high-intensity, but still exceptionally bright. Basically you put the remote phosphor (RP) plastic plate in front of the royal blue leds. The RP then shines like the sun :)...

    So today was a day of "graduation" for 4 Jamaican Red seedlings going from the Intematix nursery to the CXA High School! They seem happy about it right now :) This morning was also a day of experimentation - this time with "air pruning". Having read a great thread (props to this one go to...
