Nutrients For Auto Flowering Plants

Here at Plant Photonics we love auto flowering plants and we know many of our customers do as well, but we know from experience they can be a bit tricky to grow. They require a lot less nutrients than photoperiodic plants so its easy to over fertilize them, however this means many people under feed them and wind up with nutrient deficiencies. With photoperiodic plants problems like this are easily fixed and you have plenty of time to spot and treat any problems, but the greatly accelerated growth rate of autos means that problems quickly become serious and you have little time to correct before serious, irreversible damage is done.

I decided to search for any products designed specifically to meet the requirements of autos to make the grow as simple and foolproof as possible. I checked the websites of 47 nutrient companies and was surprised to find only 4 products specifically for autos. Initially I was also surprised that 3 of them were Spanish but then I realized why that probably was, Spain has probably got the second richest marijuana culture in Europe after the Netherlands and Spain is also the home of the Sweet Seeds seed bank which has been at the forefront of developing top quality auto flowering varieties since the beginning. If you already like or want to try autoflowering plants you can’t go wrong with one of the many auto strains from sweet Seeds!

Below are the products I have found, all are by reputable manufacturers. If anyone knows of any other similar products I would be very grateful if you could send the information (send to richardboesch@plantphotonics.com ) as I would like to add a “Growing Autoflowering Plants” section on our website.

Please note – I am not affiliated in any way with any of these companies and I have received no money or favors for promoting them!
