just a 4mm thick ally plate the same size as the HS (i clamp it on top on the smooth face) with some holes just large enough to accommodate the punch, I follow up with a 2mm pilot hole but I probably could get away with just the drill/tap. Biggest arse is the 4 blind holes I cant avoid with the...

with the drill tap combo and the aid of the jig I have pre prepared I can drill/tap the 32 M3 holes in my 1200mm HS to accept the 4 cobs, 4 lenses and 2 (four hole 120mm) fans as well as the M5 outriggers and the placement of my dim Pot/switch combo and 1.75 amp driver within 6 minutes. It used...

The degree of softness has little bearing on the end result, Aluminium is a metal, not wood, and, for me personally it deserves a degree of respect not afforded by a self tapping screw. In the same way that some choose to grow by directly feeding roots bypassing the majesty of the soil some...

just in reference to Rahz breaking his taps

I can see the advantages of the self tapping option, however for some like me, I just can't bring myself to it, just seems a bit raw and I'm sure there are others of the same ilk. For those who prefer to use screws the drill/tap combo has been a huge time saving, provided the HS is marked out...

i use a drill/tap combo bit, doesn't work so good on blind holes mind. drill and tap in one stroke. just needs good lube

Have been reading a bit further on bio-dynamics and question whether it really is so bad to supplement organics with some salt based ferts. The guys who I'm following in the high brix gardening places seem to think its OK to bring a soil into line/rebalance and in some cases to counter...

Isn't potassium the main form of lethal injection in the states? Can't be a good thing having too much of it swimming about in the soil.....

i think there is a good thread by supra on matching drivers to COBS - no point re-inventing the wheel....

I'm still building my c1750 unit, will update once its up and running, had to upgrade the fans on the c1400 unit as the case temps were getting way hot, so for the c1750 I guess I should future proof it and move even more air through it. It's quite surprising just how much heat is being...

is there a good pastis LJ?

good question LJ - Id be interested in hearing what others think as well....

what do you think the minimum size is for a recycled living soil mix when vegging plants for 2 weeks and then flowering? I'm in 4x4 raised beds (with 1000w hps) 1 foot deep with 16 plants in each which gives about a square foot of soil to each plant. I'm beginning to think that this isn't...

High all, Been having a bit of a think and I'm a little concerned about how the recent heatwave may or may not be affecting my organic grow. Tried hard to keep up with the waterings and AACT but the temps were in the low to mid 90's at canopy and i figure low/mid 80's in the soil. Soils been...

great advice, sometimes the simplest things get overlooked, went out tonight and sure enough there are a couple of light leaks from the veg area now sorted. At least the panic forced me to go out and get another fan and reduce the temps. Hopefully a better result next time...Cheers all

Hi all, hoping I can gain some insight into whats happening here. Growing in Raised 4x4 beds - 16 AK47 plants in each - 1000w hps - Recycled organic mix on its 2nd run - temps are hitting 94 - humidity low 30's. Feeding only rain water with the occasional AACT. Top dressed with EWC/Basalt...
