    How Many Gavita 750s Can I Put In A 24x10 With 8ft Ceiling?

    I see the 1000's listed for $380. However, I now see that they hook up to 240. Like the early Gavitas. I assume they will come with 120's later.

    How Many Gavita 750s Can I Put In A 24x10 With 8ft Ceiling?

    Maybe it's worth considering the Nanolux DE fixtures. I don't have experience with them but they look more 'flat' so they can be mounted closer to the ceiling. They look the same as the Gavitas but a lot cheaper.

    How Many Gavita 750s Can I Put In A 24x10 With 8ft Ceiling?

    Congratulations. I'm sure you'll like them. I love my Gavitas since day 1. It wouldn't let me attach the file as .xlsx spreadsheet therefore I had to .zip it. Basically, the light plan Gavita will help you with is to get a more or less equal 1000 umol per square meter spread. Because the light...

    How Many Gavita 750s Can I Put In A 24x10 With 8ft Ceiling?

    The can be slow. First they'll most likely ask you to fill in this (or similar) form. If you submit it to them and tell them that you want to use 750's, it will most likely save you some time.

    Watering with ROCKWOOL

    Looks great. Is FWOk the same as Mapito? Or RFX?

    How Many Gavita 750s Can I Put In A 24x10 With 8ft Ceiling?

    You can contact Gavita support. They will help you with a light plan. The trick is to calculate the overlaps and get an even 900-1100 umol m-2 s-1 everywhere. Including close to your walls. Your height is going to be an issue though. Also have a look at the new Nanolux DE fixtures. Haven't tried...

    Grow Room A/C

    Hi CJohn. I have a few questions and I really hope you can help me. I'm reorganizing and I've got my eyes on one of these for an 18KW room: This room is pretty packed with plants and I have issues during the dark hours with humidity. Right now, I'm venting during the dark hours but I'm not so...

    New and Improved

    Awesome setup. Very impressive and clean. How do you handle the humidity at the dark hours? I don't see any dehumidifiers. Is the air handler somehow doing that for you?

    How big a space can you just run exhaust fans?

    Sure you can. Just do the math on how much air you want to move. Try to filter the air as much as you can. The incoming to keep pollen, molds etc. out and the outgoing for the smell. You cannot add co2 this way but you basically keep the co2 at 350-400ppm by constantly refreshing the room with...

    UC: Light setup and reservoir question

    Thanks for the welcome Ucmenow. I always assumed the solution became out of balance when recirculating. The plants uptaking as a whole simplifies things quite a bit. Learning all the time. Thanks! As for nutrients, we always tried to keep it simple with H&G aqua flakes as the base. Before...

    UC: Light setup and reservoir question

    Hello guys, New user here but a grower for quite some time. I hope I can become a part of the family and help where I can. Up until now, I've always done Drain to Waste but I am going to try the UC system. I've ordered one of the 16XXL13's to try it out. Space, cooling and everything else is...

    16,000 W Dream Room

    Maybe helpful..... as for AC's, I'm currently looking into these for myself: These go for $2100 with air handler included. They also have a 13 Seer version: Cheaper ($1800) because they don't come with a TXV. I'm wondering about the DE bulbs though. I love them but don't they run hotter...

    Anybody running Gavitas on a flip using the EL-1/EL-2 controllers

    I saw the product videos and I love it. I'm wondering what will happen if you mix it with different wattages though. The box itself shows the wattage but what is it showing when I have 6 x 1000W, 3 x 600 and 4 x 400W mixed and start dimming? The wattage total?

    Anybody running Gavitas on a flip using the EL-1/EL-2 controllers

    They replace relay boxes. You can't flip with them.
