I haven't had much problem. I added a little lemon juice during veg to bring it down alittle. Now im just adding molasses it helps bring it down and it gives cal/mag to my nute solution.ANY problems keeping ph stable with coco? i tried a few runs with it but had ph problems,,i also tried grow rocks,,again same problems,,,for some reason with my nutes rock wool is the only one that keeps ph levels stable..dont know why as grow rocks shouldnt affect ph and coco is neutral also..they all work and yields werent affected but w rock wool it is just easier than adjusting ph every other day..have u used rockwool? do u reuse the coco or toss and buy new each run? i reused the coco and ph was better the second run, but its a bitch cleaning the roots out.. ive never had any luck with soil indoors,,always got algea or stem rot..
I join the question...What's the average yield of a 630 look like? Do they replace a 1000hps?
I understandcome on guys,, no way can a 630 cmh replace a 1k hps.. 1 315 can average 425 gpw, so a 630 would probably yield 850 grams,, a 1k gets 1000grams at 1 gpw..
i dont use the 630,, i use 315's in seperate ballasts,, i feel its better to spread them out,, 3 315 watt cmh running at 945 watts will easily beat out the 1k hps,,using 3 315's ive hit 1,400 grams,, thats 1.48 gpw,, my best runs have been combining 2 315 w cmh and 2 100 watt citizen go green cobs,, total wattage= 830 watts yield= 1,350 grams = 1.6 gpw...
so no 630 will replace a 1khps, however that 630 can get you a higher gram per watt than any hps.and the more 315's you use the better the gpw u can hit..
I ran just one side for veg... then turned both on for flower.. worked great!Does anyone know if is possible to run a single lamp on the 630w?
will I make it explode? or is it safe?
I would like to use my 630 with single lamp grow spectrum to use only 315w.
Thanks
I join the question...
What would the ideal single tent size be for the 630 watts of cmh lighting (considering all things: light coverage, intensity, and especially cooling)?
Would you recommend the single hood version or having two separate single bulb ones for the aforementioned tent?
The 630w seems like a perfect set up for 4 plants (the legal limit in Canada come October)
Here's the current opp.
Sun System 630w LEC
4x4 Light House Hydro tent
6 inch Black Opps filter
6 inch Hurricane in-line fan
Roots organic soil in 5g Root Pouch bags
6 plants from clones of my last run
5 Chocolope
1 Jack Herer
Just transplanted today 2/13
I still need a bigger fan then the 1 (6in) clip fan thats in there temps are around 82° still on a veg cycle.
I'm no pro. Any help/info/suggestions are welcome and appreciated.
