I came across a post where you described quantum boards causing cal / mag deficiencies as well as light bleaching. I use a 480W in a 4x4 and have been having a tough time adjusting the height and power of my board. I'd love for you to drop some knowledge bombs on me!
Two HLG-120H-C1050B's each running 4 strips in series for a 2.5x2.5. When I am ready to expand to a 2.5x4 I'll use the remaining 50W left over on the drivers to run individual starboards and to round out the spectrum.
Did you like the Vestas?
I plan on using it for garden veggies and weed so I thought this would be better than being fixed with one spectrum and having to double down on equipment.
The link above for humin/fulmin acids.
Tap on "andere Artikel aufrufen" on the right in the white squared area to see all available items. It's e3ay.de but as far as you can order some s***, they should be able to send it also to your country.
Should be no problem!
Yeah, I use it(Vigosol) also as foliar spray mixed with some other phytosolution products like Phytogreen-"Booster" or Phytogreen "Plantosol"(both contains lots of N and kelp extracts with aminoacids, fatacids and other usefull stuff). Phytogreen "Algensaft" is pure kelp extract. All products are 4-6€ so a lot cheaper as grow-shop stuff.
If you refer to the same E3ay dealer as I do ... he still has a few other useful things.
1kg of powdered Humin and Fulmin acids for only 12.90 € or a
molasses and seeweed based herbal bio-fertilizer with additional 1% Mg and 1% Ca, very useful when you have plants under LED's.
3,90€/0,5l, also available in 5l can's.
All my plants love it, from my 2m high kite trees to the very small succulents like the penny trees. All are grown much better in the past year since I add this Vigosol stuff to the water and for the price there can't do something wrong. I fact, I have found an almost dead Ficus Alii on the compost heap and it starts to recovery immediately after feeding it with a cpu of tea and a few ml's of Vigosol.
I brew also my own beneficial worm teas with a hand full of earthworm castings, 10ml of EM Urlösung and 15ml of bio-molasses per gallon, brew that mix for 2-3 days at 25°C.
Add 1cup of the tea per gallon water, then add your other nutes.
I actually discovered it coincidentally but it smells almost the same as Photosynthesisis Plus from Microbe life Hydroponics. As far as I can see it works in the same way and because it's much cheaper I use a dosage higher of 10ml/l per week for all my plants and they really like it
