Viparspectra xs1500

Hi all. Welcome to this run withbthe Viparspectra XS1500 which i was kindly sent to try by their helpful rep Valerie. As I have a fairly good space to use for my main grow , it seemed an ideal time to explore a few options while I wait for space to appear following upcoming harvests. The opportunity hit at a good time and has now driven the future play time. lol The light is a full spectrum 150W( at the socket) , Dimmable and very well made unit. As summer is here now , my concerns of more heat being an issue have stopped me from adding my other light so the smaller 2ftx2ft area covered by the XS1500 is a good option , The heatsink is built into the case design with a finned top to dissipate the heat so no noisy fans. Switching it on to full power was a nice surprise as the footprint was way wider than I had expected and the actual coverage is even better for my Nursery to harvest plan.... I am growing autos perpetually at present and have been able to throughput the plants with just 2 lights and using the overlaps at the edges to bring seedlings along to veg/flowering, as harvesting is finishing. The timing had been working well but the plants were getting smaller towards the last runs . I gave it some thought and Rh % came to mind. With the perpetual runs not having a higher rh in their veg periods due to other plants needing a lower Rh% in flower , the vapour pressure deficit (vpd) was not within veg periods healthier range. This current run has exploded and filled my normal space very quickly which in turn means I cannot use the same principle as the last perpetual run of bringing the next ones along ready for the exchanges. The XS1500 takes care of this issue with it being perfect for an initial nursery light that is easily covering all the new seedlings but is also able to cover my experimental "5 plant 1 Pot" attempt. I have placed 5 of my own autob seeds from a previous seeding in a single 60 L pot and intend to strip them to their 4th nodes and only allow 2 mains per plant to develop and flower. Inam hoping to have 10 mains growing in it that will be under the xs1500 solely as the other plants outgrow the lights footprint and space they are in. They will go into the main grow space once able so i can really see how well this new light can flower with the 10 mains to fill the space. Until that point , I will diary as we go and see what we can achieve.
