    Batteries Q

    Like many of you I'm using BlueLabs pens and other devices that are powered by batteries. Batteries aren't easily removed from the BlueLabs stuff. You know how it is. Sometimes you'll put something away and unknowingly that's the last time you touch it for years. I'm not going to be...

    Electric bill from tent to room question?

    I've got a basement tent with one light/humidifier/dehumidifier/heater/fans and to keep my VPD in the zone the cost has been about $160.00 a month. This will get more expensive as Summer creeps in. Has anyone upgraded a basement tent to a basement grow room - what was the savings on...

    Sun to light

    So I made some clones that are now plants in red Solo cups. I'm thinking about putting the plants outside to grow in natural Sun for awhile up potting along the way. Maybe in a month or so bring them back in and put in a tent under artificial light. Anyone ever do this?

    Changing 12/12 time of day

    I flipped some plants 12/12 this past Saturday. The lights on period is 8:00AM - 8:00PM. Today the power company notified me so-called "Time of Day" rates are being implemented. Peak power rates will be 3:00PM-7:00PM so I need to change the plant's day to 8:00PM - 8:00AM to the new rates...

    Importance of lights on/off temp swing question.

    Much info indicates a cooler lights off period is ideal but not required. My tent situation, with lights off/heater off RH bounced up to 70.1% from 50% so I turned the heater back on to stop the spike which worked. How critical is having a lights on/off temp swing and what is an ideal swing?

    Science

    I found a website that offers DIY genetic engineering courses. One of their latest courses was a 'how-to' change a plant's color. The following seminar has already passed but what are your thoughts on tweaking a marijuana plant's color? Of course there is leg-work to do. People seem to...

    Trellis netting installation if/or Q

    I want to use a trellis and am double checking on how to properly install/use. The plants are growing in a 5x5 side of a 5x10 Vivosun tent and the trellis netting size is (3.5" square mesh, 5' x 15'). How should I support the trellis so that it can support the weight? After installing the...

    UpDayDay switch

    I've got this UpDayDay fixture that has a flaky switch. There's a pic of the switch and the back of the switch. I looked at the wires and everything looked good. They are sealed so didn't pull the wires out but did force them in harder. I thought I heard a click but that could have been...

    Runtz try three

    At 9:00PM 1/10/23 several seeds were wrapped in paper towel then dropped into a cup with 10 ml of unPH'ed water for germination. The cup is now on the 'fridge. I expect pops by Saturday. While I'm waiting for these to pop I'll ready some red Solo cups with the organic soil. Later before...

    Pretreating soil

    I've used FFOF in the past and am thinking of using it again. This next crop I thought soil alone, no nutes so I can't break things. KISS No more simpler. However, every time I've used this soil the plants got the spider mites. Is there anything that can be down to soil as a pretreatment...

    Runtz and something else Redeux

    Dropped some seeds in off the shelf "Nature's Care" potting soil from Big Orange. I filled five 9 ounce cups w/soil, dropped a few seeds into each cup then watered with three ounces water spiked w/mosquito dunk. (While I have not seen any fungus gnats the mosquito dunk was added in hopes of...

    Tent Maintenance

    After a grow I vacuum the tent then using a spray bottle from the $1.25 store I spray a full bleach mist on the interior. I also clean the outside of the lights and fans with the bleach mist. If the fans are really dusty inside I'll remove the grates & clean the blades but I don't use a...

    Tent Vs Room ??

    Long story short I'm starting another grow in a poured concrete basement w/ no internal walls and exposed concrete floor. The temp down there is 64.5°F right now but Winter has just started. In the past I've grown open air and also in a tent and the results were less than the pics I see...

    Any complete soils?

    I'm beginning another grow soon. This time I'm thinking 4 five gallon buckets in a 60 x 120 basement tent. Are there any off the shelf soil solutions considered complete so nutes won't be need at all?

    Sad and Droopy plants

    For some reason these plants look sad and droopy. Otherwise they are healthy. I had an over-fert situation several weeks back and haven't fertilized since. Temps range between low 70's and 79F. RH is in the low 40%. They're not over watered.

    Pro-tips Trellis plant spacing

    About two+ weeks ago I over fertilized these plants but they made a comeback. I'll be flipping them to 12/12 soon, maybe the 15th. I'm trying to anticipate plant spacing under the trellis. I had eight plants but decided to eject two because I could see future overcrowding as an issue so...

    Here I am again. I gave them GH Trio nute solution dosed according to the new GH chart for late growth four days ago, this past Tuesday. EC was 1.6 and PH was 6.5. Temps are between 64 and 69F. Eight plants are in soil, 100% Promix HP CC. But eight others are also in the cloner and...

    Ideal PH Target range

    I hand water, growing in Promix HP using tap water. Tap water PH is ranging between 7.1 & 8.8, even after sitting in jugs for a few days. PH seems to fluctuate. Using PH down seems to be unpredictable. Sometimes I'll add a 1ml squirt to the gallon and PH will fall 1 point. As a result...
