Yeah it's all about magnetic ballasts for cmh. The problem is the frequency, digs are too high generally. Some digis are low frequency, but i think only a select few of those will fire the cmh. Check out advanced tech lighting. Just google the name. They have some good cmh info, and very good...

I wouldn't be too sure about this. Thc doesn't degrade until at least 60 degrees Celsius especially not when it's growing. In fact you could argue that since hps is warmer it is more conducive to more potent bud since the warmer temps help open the stomata and transpiration increases, more nute...

I will have to measure when i get home. I would guess around 10in. It really didn't stretch much since i was pretty aggressive with my super-cropping and pinching. In hindsight i think a little more stretch could have increased the yeild if i also defoliated a bit more. Still happy for the first...

I would seriously consider a ceramic metal halide in 150w. It would be my choice over hps for certain, it's a close one to led for me. I feel like led really needs you to optimize the plant to get a good yield where as the cmh might be a bit more forgiving. Cmh is also slightly cooler than hps...

Yeah she might be a zip or so, but ill be surprised really. As for veg pics, i don't have any before i put the screen on but it basically bent over gently and crossed about half the screen. I topped before this and waited for the new growth to start on the new tops before the screen went up...

Good eye! I actually have a rainforest 66. It has a 13gal res. I have only 3 plants in there. One is a tiny runt that I might cull.

Looking good dawg. I'm a little worried about my aero system since the roots are so massive and the thing is still in veg haha. I've stopped using floaraliscious plus because it dyes my roots brown and makes it hard to tell if I have rot or not. So until I get better with hydro, I will hold...

Haha thanks Keep a journal of your grow, ive always wanted to see a led pc grow. I love micro grows, it's just so creative. It will be a fun grow for sure

Haha nicely put. Fortunately my Rez has been pretty controlled temps since I switched to 30/30 (minutes) on off, I'm surprised the like it too. Haha. Oh it's a rainforest 66 setup. I have used h2o2 in the past, I like the idea of a sterile Rez, but your right. Eventually you lose. And finding...

I'm a little new to teas, whats the concept behind them? Your adding microbes and such to a chemically fertilized res? what will the microbes eat? What is the benefit? I'm just getting back to hydro, been keeping it simple since. Thanks

Right on, if it'll fit and its not too intense I'd go for the led. Just try to get the widest angles lenses you can, since they really need to spread in a short distance. Should be a fun grow! But really 18 in isn't much to work with, i would just lst one plant in there or mini scrog, good luck!

Haha nice.......

Very fruity, nice and sweet!

Sounding and looking good. What are you planning to use for your screen?

Wow replies i missed already. I wold maybe pop a snow white, its my personal favorite so far, a really nice strain and decently short in stature. Best high i have ever had.

Do you have all your ph and Tds meters? If not i would definitely grab a cheap digital ph meter and some calibration solution, check the runoff and make sure your water is phing ok. I only mention this cause i used a new soil last grow myself and got off to a poor start due to my ph meter...

With a lot of the modern LEDs I would be a bit worried about the intensity. i mean you have 18 in of height, which leaves maybe 12 after the light and the pot (at best) most lights start getting a little dangerous any closer than 12in especially the newer generation. I would go 50-100 w of mini...

As a rough guess i would say at least go double your veg room in most situations, so 4 lights for your flower room, 5 if you can afford.

I went with the first company on that list. I was happy to see they actually had 740 which is the wavelength i really wanted, all i could ever find was 730, so very cool indeed. It didn't have prices or anything, vut i put in an order for 12 units. My plan is to but em in about 2 banks of 6...

Wow that site is awesome, I need to digest it a bit, but it really takes a load of since the Turkish company I was trying to use won't respond to emall. Such a great find, thanks a lot. Depending on order difficulty i should have the lights and array built in time and on schedule to start my...
