If its your first time doing scrog, take a look at that guys journal. he documented his scrog and pulled 1 pound out of a 600HID https://www.rollitup.org/t/single-plant-600w-4x4-dwc-scrog.948296/page-9

Been wanting to try out the cali connection GSC. Subbed

how was bubblegummer from female seeds and black D.O.G from HSO?

When did you get them?

When did you order the seeds? I heard that the blue dream from hso has been garbage for the last year or so. I popped one yesterday and hope I got good ones. The seeds are very small.

Ah okay cool, I though they were going out of business. What strain do you guys recommend from sin city seeds? I need high potency high yielding. Is white nightmare the #1 for that?

Whats going on with sin city seesds? I read that their white nightmare strain was a good catch. I want to look into it but their website is down and disappeared.

Is doing a double scrog net worth it?

Bought a whole 4x4 kit from them and would recommend except for the high frequency electronic ballast

If you are exhausting, you absolutely need a negative pressure or smelly air will leave without being filtered. If you are scrubbing, you need to filter the air 5x per minute(what I have read). I'm guessing that your 8" fan pushes about 700 cfm which is 15% of what you need.

I need someone to explain what the rated output voltage means on the hlg. I want to power 3 vero29C SE at 700ma to get 150 watt I would use the hlg 120h 700c. What about the rated output voltage? The max is 54 and the vero29C SE has a voltage of 68V

I have a 10'7"x8'7" room for my grow. I already have a 4x4 tent with 600w HID. I want to get the most out of the room while being stealthy and practical. The room is rectangular and has has 1.5'x2.5' closet. I am unsure how to design it. Would you recommend filling it with tents or...

Turn off the hps light. It changes the colors.

Your suggestion is the best bang for buck and if it was my most important criteria, I would be a fool to do otherwise. Sadly I am limited by the amount of power I can use. So I have to get the most efficient and affordable setup I can find which I believe to be the one I posted.

Why would you recommend a current of 1400? I can drive them at 700 and get a much better efficiency according to the data sheet.

where did you see the operating drive of 1710ma? That would mean it would have a minimum wattage of 118.7.

Efficiency is not linear so you can't use that formula to obtain it. On the other hand, you can find it in the excel spreadsheet on the manufacturers website. Regarding the temperature, most people use 3500k for the whole grow. I am planning to use 3000k 90 CRI for my flower tent.

I want to use 5x vero29C SE driven at 700ma to give me a total of 238W since they use 68.1 volt each. I want to use a meanwell hlg 240 to power them but I don't know which one to chose. I read somewhere that the driver needs as much voltage as the cobs need. So 68.1x5=340.5V in my case. The...

Hey cobkits, I saw you talking about the next Gen stuff coming out in the next 2 months. Do you know if they will be affordable? I'd like to illuminate either a 2x3 or 3x3 flower space soon.

I currently have a 4x4 tent with 600 HID doing a DWC. I would like to expand and get a 6x4 tent for flower and use my existing 4x4 for veg. I would be doing manifold training. I would also like to do a bucket system with res since I will be running only one strain. 4 plants in veg and 4 in...
