Less than 4 hours later - pH back up to 8.1 - just threw in more acid kicking it down to 7.6. What a nightmare - if this doesn't smooth out at least somewhat - I may have to resort to a new water source.

added ph down (too much), ,then ph up. It is now at 7.7, a slight decrease from 8.3. I guess I will check it again tonight. Does adding both ph up and down make the solution more stable, i.e. have a buffering effect? I feel like I'm going to have to adjust this several times a day if I'm going...

Sorry for no pics this post - so I came back from a trip and at 8 days after germination I saw 2nd set of leaves on just about every plant. The pH had risen to 8.3. Damn. So I mix up a new batch of tap water (200ppm and 8.1-ish pH), add 7ml per gallon (1/4 strength) of Botanicare Pure Blend...

Thanks for the tip on Lowes. They had 6500K in the 23w "flood" package. 8 are directly above each pot, and I have 2x 2700K/23w up higher to fill in a little of that spectrum. Going from 4 bulbs to 10 made a HUGE jump in box temps - and stupid me I didn't pay attention that my timer outlets...

PS - these are not halogens. They are the Philips "flood" CFLs. Just a CFL with a "flood" reflector/housing around the CFL tubing. Philips makes the 2700, Ecosmart the 5000. Here are some pics of the Philips. They are more expensive, but the reflectors are amazing, and eliminates the need for...

Yeah man I SCOURED the shelves at HD, target, wal-mart must be a geographical thing - only 5000k is on the shelves here for daylight lamps. I plan on throwing in some of the 2700s also - still figuring out temp control with lights and fan. I guess I could have gone online to get the 6000 or...

23w, 1100 lumens, 5000k daylight. Best that home depot had to offer. I wired 13 sockets, all height-adjustable. Only using 4 at the moment until the other plants poke out. I have 9 2700k lamps, same wattage and style, standing by. The idea here was "sea of CFL". Actually, the original...

Hi everyone, FINALLY got my grow box / system built and running. I am starting off with a couple of bag seeds and the freebies I got with my attitude order. Problem is that ALL of the freebie seeds have popped, and now I have what is shaping up to be 11 germinated seedlings, and only 8 pots...

That's not flip, it's a great data point. My local hydro store, who don't really "push" things on me, said the cleaner (I think I got clearex or something) was a MUST. But who knows, maybe they don't drain/refill, or use enough bubbles, who knows. Good to know it isn't necessarily a MUST...

I don't know if "flush" is the correct term, but the process where you use a cleaner to wash out salts or whatever to clear up nutrient lock-out. How do you do this without a pump / stream of water at the net pot? Is the Bubbling action enough to do this process, or do you pour solution over the...

Hi all, first timer here, building a box and bubbleponic setup now. My question/issue is that while I expect some seeds from Attitude in the next day or two, I already germed some bag seeds a while back - one popped a root - and is about 1 inch above the wool now. ( I packed hydroton and wool...
