I have used tools plenty before but it seems everyone keeps mentioning the type of material the bit is made of and that's where my issue was. I could have a drill bit made entirely of diamond but it wouldn't do shit it's the type of bit. I had a bit specifically for mortar (the flat headed...

I will at some point but they are very expensive here, well I could get the cheapest one which would be the equilavent of 100$ but I'd rather wait if I can and invest in a better model maybe Christmas or something

Must definitely be the wrong type of drill bit then. Can you possibly send me a link to what you mean? I am struggling to find it locally. I've found these: but they don't seem to match your description of a V angle. https://www.amazon.co.uk/Draper-Titanium-Nitride-Coated-Pieces/dp/B009RM356I

A drill bit won't drill through metal without a divot? That could be my issue, after drilling my last unit I felt like I had just done ten thousand dumbbell curls on my arms from pushing so hard on the drill for hours

Definitely not in reverse! I understand it's soft but so far I've definitely had issues with drilling! I'll go get a center punch and see if it makes a difference

i have got the best quality bits from local hardware store but they don't drill through aluminium well. I guess I need a specific type of bit I'm just not sure on the type like a tungsten carbide, or diamond drill bit etc. I have a tungsten carbide one atm it kind of has a flat head like it's...

What do you use to punch, pilot hole, and main hole? What kind of drill bit etc

I must be doing something wrong when I drill holes into aluminium angles for the screws to connect the circular heat sinks too. I have used a sketch piece of paper of the holes on the heat sink and then used that as a guide when drilling but the drill bit slips 99% of the time and I have to...

Exactly what I needed thanks. How many watts do you run each 560mm long strip at?

What's the difference between the 350 nominal drive current and the 700 on the data sheet? https://www.bridgelux.com/sites/default/files/resource_media/DS131%20Bridgelux%20EB%20Series%20Gen2%20Data%20Sheet%2020171020%20Rev%20A.pdf BXEB-L0280Z-50E1000-C-B3 is the 5000k and it says 350 nominal...

Great cheers I've found a supplier for them decent price depending how many I need. How long are they? Can't seem to find dimensions Edit found data sheet... 28cm long... depending how close u need them width ways they are cheap as hell

You reckon you can't get 50 clones from 5 weeks growth?

I like the look of those but need more info if you don't mind. I spent hours and hours researching cobs to use and went with 4 x citizen 1212 per square foot so that I have a 55% efficiency. These strips seem entirely new to me. A single flat piece of aluminium will be enough to cool them...

30cm distance between tops of plants and the light fixtures I reckon. Plants won't be very tall bonsai moms and clones that are beggining their mainlining for 5 weeks before going into veg room

Only other option I can think of is if there's a way to mount cobs on something that's a lot lighter than aluminium heat sinks

Not sure what you mean by sizes? The length of room is 70cm wide 4m long. How hot do t5s get?

im finally building my mother/clone room after finishing the flower and veg room. Flower and veg room use high spec cobs custom built and cost me a fortune making sure it was extremely energy efficient. I'm thinking of not bothering with cobs at all for the mothers and clones simply because I...

I'll test anyway but just figured if someone else already knows it's ok to do I'd just through all my clones in rather than waste time testing with 1 or two. If you used the same fert level as your mums and they didn't get net burn and rooted faster by doing it I don't see that as a waste of...

You say if you let them get roots. What about before they have roots? If I take the cuts and put them directly in a cloner in the same resevoir as the mothers with same ppm?

I will get enough clones from the plants with 5 weeks of growth before I take clones. My main concern is the clones getting the same nutes as the mother. So was wondering if there was anyone here who feeds newly cut clones the same nutes as the mother plants
