Most of the week was spent setting up the hydro grow. Needed to build a DIY chiller since air temp in our grow room is hot, and water needs to be a good deal colder. Fridge from kijiji, garden hose, fittings, and submersible pump all in were under $100 but knowing what I know now I'd likely go with a thermoelectric chiller (DIY, with power supply and temp controller) next time around. Looking forward to tracking metrics and seeing how it goes :). Seems there's a lot of contradiction in terms of level of nutrients recommended, max water temperature, using H2O2 to boost water temp that can keep algae and rot at bay, etc. Got my hands on some Hydroguard via Amazon... despite local shops saying you can't get it in Canada... so I'm going to go with that instead of H2O2 to start, despite water temp getting up above 21 C (70 f) during the day. Fingers crossed.
Update - keeping water reservoir tank under 20 C now by using reflective bubble wrap insulation on the reservoir itself and pipe insulation as well. It's a 10 C difference from the room temp, so I'm SUPER pleased with that.
@Njaak, I would personally do a pretty heavy defoliation now since she should start flowering any time. I would start on the bottom and remove the first set of nodes on every branch and remove any little budsites that aren't trying to grow up. Then pluck any big fan leaf from the top that is blocking light to lower buds. There is almost no recovery time like you would have in soil so it is pretty hard to over do it at this point. She will bush out again pretty quick and if she is nice and clean when she hits her flowering stretch you will end up with more top buds. She will like the better air flow
hey bro, she's looking strange... looks like she has been eating a lot, no? I wish I could help more, but I've got no experience with Hydro yet
I wish this lady a happy ending.
Tchau, do Brazil! =]
@amazongrow, Yeah man, she's drinking / eating TONS. to the point it's a bit crazy. only thing I've not ruled out is pH. My pen might need to be re-calibrated.
Agreed about the deleafing needed.. maybe a lolipop too.. time for the fans from veg to go.. by now I usually start removing all the leaves that don't show any signs of trichs.
Not all at once mind you but I do remove the leaves laying on top of any buds around 6-8 inches down from the tops with indicas, less with sativas, BUT! I leave the top several large fans as these are the "pumps" or rather the transpiration that takes place will draw up the sap from the roots and bring new nutes to the top colas.. and any buds below as well.. it's a fine balance... Cheers bud!
Hey man, try adding a few extra feet of airline, get an IGLOO like cooler and lay the extra airline in the igloo, add ice and close the lid best you can without pinching the line, or drill two holes in the lid for enter and exit... This will chill the air going through the line and given enough time, lower the temps in the res. Once they're down to temp, reduce the ice amount until it stabilizes.. a couple of frozen pop bottles filled with water should do the trick.. two in the freezer and two in the cooler.. depending on the size of the cooler determines how long the ice lasts..
have fun playing around with the length of line too, just don't overwork the air pump with too much line...
Cheers! Keep it Green 👌 DWCHC 👈👍
The buds still look great! Nothing a little trimming won't fix. I spent more time calibrating my pH pens then I did using them. The GHE test drops are the way to go in my opinion.
@Njaak, Damn, I think you told me that before. I have heard that some of the high dollar pens hold calibration for a long time, but I am too cheap to find out for myself.
@Wicked_Stix, if I could keep the room temp below 25 C, that's exactly what I'd do. Unfortunately the grow room is in a 5 ft tall basement storage area, with the only air flow via duct fans, and with a massively over-powered light that sheds waaaay too much heat. We struggle to keep the air temp down and humidity up. I could ditch the high output light and just use the older less powerful (and less hot) light - basically trading off yield for ease of growing (if I could keep the room cool enough to ditch the water chiller). Plan is to build up a much better grow room in the garage for the fall indoor season. TBD, but it would be awesome.
Nice setup. I just started a FBTO1 in a dutch bucket. Some tubular pipe insulation on your hoses will probably help the temp a couple degrees. I will follow along. Good luck!
@Wicked_Stix, thanks! Yup, put pipe insulation on the outside of pipes that aren't in the grow space. Kept the section inside the tent uninsulated to also help with air temp. Any little bit helps :)
