I would like to know how many hours of life we can extend LEC systems, both ballasts and light bulbs. Unfortunately I have not found reference material that explains how much we extend the life of the bulbs at medium power My intention would be to connect a 3x315 configuration in a 3x1.40m²...

The leaves are all droopy and yellowing followed by brown spots on the leaves. This happens when the introduction of the CMH happens. Switching fully to CMH but want to know how to remedy. This has happened on the last 3 runs. Even though the plants look like crap they still finish better than...

Hello everyone, I was just curious if anyone around RIU knew how many watts of CMH lighting per square foot is ideal? I am starting up a new, quite small vegging tent and am curious if a single 315w CMH fixture will be adequate. The tent size is 2ft x 4ft x 5 ft tall. Appreciate any and all...

This is the start of my 2nd grow with my CMH light. I have 7 Wedding Cakes, 6 Purple Punchs, 1 Peyote Critical, 1 Blue Gelato 41, and 1 Cheese that have been germinating for 2 days. They have all opened up and I'll be setting them in 1.5x1.5x1.5 rockwool cubes. I will do my best to log my grow...

Hello all, starting my grow journal so I can keep track of my grow and thought this would be a great place to start. Here's my set up; 5x5 grow tent 630w cmh dual bulb grow light 16 Animal Cookies clones 8" 780 cfm inline fan with speed control Charcoal filter Using open ports as passive air...

So my first attempt at growing with a CMH/LEC I nearly lost my whole crop. With in 2 weeks of sending into flower I had all sort of deficiencies showing and at 4 weeks decided to flush as plants had locked and switched back to a HPS. Ended up helping alot but my yield was still affected. I came...

Just setup a 32x32x63 flower tent and was wondering how good of a setup it would be to mix a mars hydro 300w with a 315w lec light with the phillips mastercolor 3100k bulb. Any suggests would be helpful mantaining a temp of around mid 80's.

Is doubling up the wattage with the 630's worth it in a 4x8 or will the 315's get the job done? Does anyone have any recommendations on any of the brands offered on amazon?

Hey everyone. This is my first time on the forums so hopefully this comes out right. The plants are White Widow grown from seed in a coco perlite mix in 7 gallon pots. I’m using advanced nutrients at about 25-50% strength. I vegged under t5 until about 10 days before flowering then switched...

Howdy y’all, first time posting on here. I’d like to hear anyone and everyone’s thoughts on what i’ve got going on. So, basically i’ve got 6 x 315w LEC’s over roughly 140ft^2. I’d like thoughts on my crossover and spillage of light. Looking forward to seeing what y’all got to say. Thanks! CL_IV

What's the difference between those single 630w double ended cmh setups vs the ones with 2-315w bulbs

4x8 tent but only using half so I can start a some what perpetual harvest. Currently using 2 315w cmh in that area. I just ordered a third one this morning.. 6 in fan/filter that works alright. Installed a/c in bedroom for cooling purposes. I use one wall mount fan . Probably should look into...

will 4 Sun System 315 LECs be sufficient in an 8x8 tent?

Is it possible to use 3100k & 4100k bulb simultaneously in a 630w (315w x 2) unit? I understand 4100k is for veg and 3100k for flower. I figure broader spectrum with both bulbs in use. Anyone doing this or are most of you cmh users running 2 3100k in yours? Thank you for your inputs! Apologies...

I'm planning on setting up 3 4'x9'x9' rooms. Each next to eachother on their long sides. I want the rooms a little bit bigger than the light footprint to give me some elbow room to work with hence the room sizes. 2 rooms will have 2 315 sun system lec each with Co2 alternating veg/flower...

1st off i suck at writing! bongsmilie:bigjoint: I decided it is time for a different thread as the last would not represent my room anymore. I have made the CHM/LEC plunge full on, replace all the HPS/MH with comparable fixture as what i had before. This will be the beginning of my try at...

about to put my 5x5x7 tent up and i was thinking about running 2 sun system 315 watt LEC. Anyone had good luck with these?

Looking to get some good ventilation in my 5x5x7 tent and was wondering what are the quieter inline fans out there and what cfm fan and carbon filter should i look into? Thanks

Looking at firing up my 5x5 tent with 4 ft 8 bulb t5 for veg and (2) sun systems 315 watt LEC 3,100K for flower. i will be running an inline fan and carbon filter during flower to help with environment and smell but my question is how do i maintain proper c02 levels. should i go with an...
