I've just cobbled together a cree based light Cxa3070's running @ 1400mA 4x warm 1x (cool or nuetral, can't remember, broke one led while building, was meant to be 6, a cool a nuetral and 4 warm ) Plus 10 3w deep red/royal blue -phillips luxeon and some other I forget ( top spec I could...

Anyone here have experience growing with diy cob leds? I can't find any reference on MP which is a shame as I've just built a diy led ( I won't elaborate but a quick online search for 'diy cob grow light' or 'battlestar ganjactica' will yield all the info and simple designs by those responsible)...

Growing liberty haze I'd say pretty unstable, relatively new strain and a cross of g13 and chemdawg ( both of which have genetics shrouded in mystery )

thanks thc, they have greened a bit, and the bunch/rosetting slightly decreased . the lower third wasnt guna get adequate light anyway i realise so losing the foliage will prob help increase airflow and give me room to top dress as ive wired down all the branches its hard to see the dirt where...

hi thc i got some shots in a more natural light ( well, bathroom flouro ) i think im stressing a bit too much and that the symptoms remaining are just what the plants will bear as 'scars' from the multiple minor mishaps like soil ph being out and a few brief periods of high temps due to my...

also i found a graph like a circle with all the elements around it joined by lines, it seemed to explain how one element effects another regarding plants i vaguely got the idea, more of one element necessitating more of another, or slowing the uptake of another, solid lines with arrows and...

they were looking spot on for a day or two, they had vega 16ml in 8litres of water two days ago now looking like this, im not sure if they are 'rosetting'/'bunching' or if its normal, looks to me like zinc def but i think theres zinc in biovega worries me that if ive fed with zinc in...

Definately wasn't working ( up to 40c ) , maybe with more extraction but in this case no, Will be returning to 125cfl + 430w hps ASAP Two 400s will have to wait till I have bigger space/ extraction

Lool as I suspected.... My Osc fan isnt creating an 'outdoor' kimd of breeze it's pretty wimpy 38c now. Definately not enough extraction, but it was worth a try I shall stick to 125w cfl + 400w hps @29/30c I might have attempted a 32c grow but not 38/40 that's guna hermie or die for sure...

I'm battling with slight heat issues 34 degrees c at best since adding a second lamp to my groom Just wondering if anyone has a morale boosting success story of any hot hot hot indoor grows that produced well despite temps being higher than the widely accepted maximum I've successfully...

Hi people, lights on in 15mins- I reckon I'll probably have to switch one of the lamps off after half hour, I suppose if the temps go up slower it means the problem is less severe. it flew up to 40c with both lamps @ 10" (which is where I'd love them to be but that's not gona happen) Air comes...

Plants are looking great now, symptoms have not progressed and growth is looking healthy Seven days from switchover not showing much in the way of flower development But it's early days yet maybe just getting over stress I think they might have been limp and rusty spotted by now without the...

Hi all I have a lighting Q for you, I have 1x1x2 space with 4" in and 6" out I was running 400w hps + 125w cfl at a 17" distance getting temp of 29c Im now running 2x 400w hps at 20" distance getting 34c Lumen chart says I'm getting 50% lumen increase for 6 degrees heat I could raise them...

Thanks short, Its the 'p' I want to be available, there's little/no N in the guanokalong powder, I was kind of hoping the guanokalong would be a good organic PK and I want to time it right, if you think the calcium content is not a problem thats cool, I will top dress now, and again maybe 5...

Hi all, I gave them a light flush ph7 Top dressed with the fresh ewc mix And then a watering with tea mix ph6.8 with levelled tablespoon of Epsom salts ( in 5litres ) I aerated all waters and the nutrient mix overnight and the ph stabilised to 7.1/7.2 so only needed small amount of lemon, I...

I have a quick one but tough, I could only find extremeley limited info on google most of it fish tank related, I know the ph of my aerated water goes up partly due to co2 being forced out so theirs less carbonic acid Am I right in thinking that (along with filtering out the cal carbonate )...

And thanks for the chart thc, I've never seen that one, I'm always picking the canna leaflet up in the grow store, but that wasn't on it

Thankyou for all your advice, I've collected a load of ewc for the top dressing I'll let you know how it goes

HP i gave them 7 litres of water with 1ml per litre of hygrozyme. by drench i meant just really wet with slight runoff. wouldnt call it a flush - the runoff amounted to 200ml or less i poured it from tray to measuring jug to test the ph tips on new growth a bit pale still even though new...

whoops i have to admit something- my cfl was still on 24/0 and only my hps was on 12/12 no wonder they havent started to flower - the stretching was just due to lack of light for 12 hours a day ( only an old 125w grow/blue cfl on a metre square) luckily they only climbed inch or two theres...
