I did miss it, sorry. :( [URL="https://www.rollitup.org/attachments/hydroponics-aeroponics/222136d1224544372-al-b-faqt-sspx0068.jpg"] Looks like heat damage. You're looking for 24-26C (75.2-78.8F). You have a peak-memory recording thermometer, don't you? What has the temp range been at plant...

Thanks for the thanks, bert. :) You might look at the Odorsok line of carbon filters. They are available in several lengths and diameters, some are especially well suited to smaller grows and limited space applications. Carbon filters should be driven with a centrif blower. I use UV...

OK, I can see why you did that, but you're looking to shift the plant into flowering even though some veg growth does occur in wk1-4 of flowering. Providing the blue-biased spectrum isn't helping the cause of forcing flowering. I do like metrics but most EC meters display in ppm instead of...

Yeah, that's what I''m talking about, the cut of the blank and the roll/polish of the edge. I'm a -4.75 to -5 so my lenses are thick. With a rough cut edge and no roll & polish, not only does it look bad, but high-index polycarbonate will chip easily unless an edge break is put on it. Can't...

A spare, unused 20A ckt? Woo hoo, lucky you. :D

Like I said, no need to flush anything.

The pictured MH stadium grow looks great. Wonder what it would look like with HPS. Cannabis plants make best use of re-yellow spectrum in flowering as that is the character of late autumn sunlight at temperate latitudes due to the low angle of the sun causing sunlight to pass through a long...

Too easy, just do a DWC with a low water level. When you finally buy an HPS light, you'll know the difference between bumfluff and solid nugs. My criticisms are not based in opinion but in the simple facts that an Aerogarden is too small to grow cannabis plants and CFLs yield fluffy buds.

coolio. :) Will keep an eye out for him. :) yeffir, now you've got it. :) Yes, those nodes eventually will form branches, but cutting it as you depict will force them to get a move on.

Thanks for that, iloveit. :)

brilliant, fitzy, thanks again for your help. :) 35% is fine, just use it at 1.7ml/L instead of the 1ml/L rate for 50%.

You can smoke the output of a bog standard Aerogarden faster than it can grow it. Aerogardens are too small for cannabis plants, simple as that. You have to add proper HPS lighting to make them do anything at all, and then you find that there's insufficient space for the rootmasses of the plants...

Fan leaves don't have bud sites. Leaves cannot be cloned. I don't use humidomes at all. See https://www.rollitup.org/hydroponics-aeroponics/15030-batch-clones-rockwool.html Please cite nute strength in ppm instead of EC. I don't know the EC-ppm conversions off the top of my head...

If you are topping up the tank frequently, you should see the EC drop as the plants consume the nutes. IOW, if you mix a tank of 1000ppm and run that for several days, then top up the water to replace that used by the plants or evaporated, you should see the ppm drop a bit.

Completely off topic: When I drop $1000 on a new pair of spex, I expect they'll be assembled correctly and I'll pick them up without waiting or dicking around. No quibbling. That's not what has happened today. I got every excuse in the book for why the machine which is supposed to cut & polish...

Hellfire, Jackson... you otta meet my Uncle Dad. :D It's all but impossible for the DNA of a plant propagated by asexual means to have any difference from the donor plant. I last sprouted Sweet Tooth #4 beans in 2002 and have propagated by cuttings ever since. If the DNA is gonna...

Just browsing through the S&P sales lit. Very complete specs and some good installation tips. I have a 150mm axial on my cooltubes and another 150mm blower on the shelf. I think I'll have a play with putting the spare inline with the existing 150 and see if the increased pressure drops the...

zackly. They stall, but any significant pressure generated will vent backward between the blades as well. Possibly. I understand that dating yourself is still legal in Alaska, though. :lol: Cooltubes tend to flow air a bit better than hoods. The metal body of a hood also can heat up easily...

No need to flush every 2 weeks; in fact, this can cause problems. A soln with very low EC can actually suck nutes out of the roots. You need only clean any debris out of the tank when mixing up a new batch of nutes every 2 weeks, no need to flush the plants.

You're shooting the pH too low at 5.3. Needs to be 5.8. At 5.3, you are locking out N, P & Mg. Keep in mind that deficiencies caused by an actual absence of certain elemental nutes are extremely rare when using a commercially made hydroponic nutrient. It's much more likely that a pH error...
