very busy in the garden this weekend. let's try to recap:
flower chamber -
gnat control underway. no plant damage, no real issues other than need to get these fuckers before it becomes a problem. DE across net pot tops in the morning, also dusted all surfaces below the canopy. about 12 hours later had brewed up a gallon of azamax at max strength for drench and foliar. syringed this down into all the net pots / coco. had a few crawl out like "wtf now?!" so looks like we are hitting this at the right time. i would have dumped the couple of fl oz that the bottle calls for when treating 15 gals hydroponically, but that's fucking expensive and this bottle of azamax was supposed to last forever. We'll see how it does and press the attack if needed. Also got yellow sticky traps down under the canopy.
I am 99.9999997% certain that these gnats came from me hanging out with the door open and light on. Especially when it was hot a few weeks ago and fresh, unfiltered air was being drawn into the room. No more of this now that CO2 and AC are in place.
PH drop is insane as always. I'm going to treat this now as a case of too small a res for 6 plants. Remember, I increased the number of plants going in to see if this problem would get worse. Next run we do no more than 2 plants in here and I bet this becomes much more managable. PH was 5.9 at 5am, 1pm it's 4.2. For now I am just going to upkeep it with ph up as I can. I am seeing a few complaints on the plants that look like they want more food. Thought it was burn but the way the edges are curling a bit (just a hint of this starting) makes me suspect they were much happier on the 1500ppm diet. Since the PH drop hasn't changed one bit on the lower ppm diet, I'm going to bump it back up. Sorry Joz! Will flush it later today.
Half concocting a way to increase the res size for this cycle by adding a 20 gal drum and recirculating it. Mulling it over.
Stopped by a new hyrdo store touting their "vortex tea". Free half gallon with any purchase, so I threw some of that in there. wtf not? Also dumped in the rest of last week's VerimtT. Fuck it!
The hydro store guy thought I could get a handle on this ph drop by using a silicate product to raise the ph. It worked about as well as I figured it would, although this stuff does work surprisingly well as ph up. Dyna-gro pro-tekt silicon solution. I probably dumped 150ml of it in there over the course of a night. Zero difference to the ph. We'll incorporate this into the diet anyway but it's not the solution to ph plummet. Maybe this plus a little azamax treated proactively would help keep critters from getting a good foothold.
Veg cab -
Looks like it has been snowing DE in there. I piled it around everywhere. All over tops of pots, shelves, really trying to hammer the point home. Experimented with dusting leaves with DE. Result - eh. Once it's on the leaf, its on there until you really spray the shit out of it with some fluid. Wiping won't do it, nor will pouring. It has to be pressure washed off, and even then it's 3 or 4 washes. I don't know what the plant thinks about it. If plants can tolerate it, if it doesnt dry out the leaf or something, then it might be effective to dust the hell out of the whole cabinet at lights off and wash it out again just before lights back on. Don't know what it would be worth, but a bellows full of DE blasting recklessly should at least communicate to critters that the environment is becoming more hostile.
Started attempting to repot each clone to check out / get at the inner roots. I do not like the root conditions. Not looking really bad, but what was white is turning brown. No more extended stays in party cups for clone. Too much standing water caused this root brown and likely helped lead to the bugs. From now on everything must drain. Duh yeah I know it sounds kindergarten basic but these plants were doing fantastic in this stupid party cup setup for .. 5 months now? No problems until the last 6 weeks, so as long as they aren't in there for too long it's no problem. Well until the bugs show up anyway.
Got halfway through the cab, will finish today. Was very surprised to see aphids on only one of the plants, a blue dream in a party cup. Saw just two or three, a far cry from the population explosion seen earlier in the day. DE fucked them up I suspect, as I really laid it on thick there. Maybe the DE kept them limited to areas of the coco and roots that had been treated with (and were partially still soaking in) azamax solution.
Each one was pulled out, all of the coco removed (EASY with croutons. Why are croutons not stocked anywhere? Total bullshit that I have to keep special ordering this awesome medium. Waiting 2 weeks now on a bag .. ), then sat into a corona bucket with about 1/3 gallon of max strength azamax. Immersed them to the top of the rockwool for a few minutes and gave them a far too strong spray blasting of the same azamax strength. There is no way that azamax has not penetrated every single nook and cranny of each of these now.
Repotted them into various containers, mostly 1 gallon pots full of the last of my coco croutons (which i checked to be sure they weren't harboring bugs. none found.) or hydroton. wow hydroton is a pain in the ass. I am planning on pulling them back out and possibly repeating the process in a few days, so these aren't any sort of permanent homes. However, they are completely drainable.
Dusted DE around the pots and media as I was potting stuff. Placed pots onto trays, also dusted.
Placed the trays under my new 1000w HPS, in my new grow tent. This is my long term bug solution. Don't let the clones sit around. Flower them, keep the ladies moving rather than sitting in a veg chamber being over pruned, waiting to pick up crawlers.
Will spec more of the tent later, but it's super simple. 4' x 4', 1000w HPS in a yeildmaster II 6" with the usual white cheap magnetic switchable ballast. Nice deal on this setup from gc hydro at $220 with an ad in OC weekly. Must have the ad if you go for this deal. Was about to chomp on the exact same hardware for $225 used.
It came with a $63 sunmaster bulb that I think is complete garbage. Will see what the holdup is, but I can tell you right off the bat that my 600w cab just obliterates the light output of this cheap 1000w. Maybe its partly the reflectivity of my cabinet, but it's no contest whatsoever. The 600w lumatek digital with the lumatek hps bulb is far, far brighter. Will upgrade the 1000w bulb soon and see what's what then.
I modified the airflow as follows: air now enters the 1000w fixture in the tent, exits into the cooltube in the cabinet, then exahusted as usual. So just using the one S&P fan to pull both lights. Working just fine. I have noticed zero temperature difference in the main cab. Will be checking this again when the 1000w bulb is upgraded.
