    New 18 flower room nearing the finish line!

    We could have lollipoped more for sure but we took off most big leafs, especially since we were battling spider mites so taking off those leafs help that as well

    New 18 flower room nearing the finish line!

    Realized I haven’t updated this in a while lol but we pulled down a while ago. It’s looking very good and it seems like we’re going to hit over 2# a light which is more than fine for how rough this operation turned out. Only having 2 people for 30 flowering lights is a tad hard at times. For ipm...

    Cheap alternatives to overpriced hydroponic nutrients

    I use power both power si products because they seem to work the best for me and what I’ve tried so far. I do .5ml/gallon for the regular one and I do .75ml/gal for the bloom. I usually cut it out around the beginning of week 7 in flower

    Cheap alternatives to overpriced hydroponic nutrients

    I’ve ran jacks in coco and the mg levels were more than fine for me. A 2:1 ratio of ca to mg works more than fine for me and if you’re getting runoff it’s shouldn’t be a problem. Jacks is a great formula all around. Adding some silicic acid will definitely help as well I’ve seen how much it...

    What's the Best Pest Protection Spray?

    most common ways are usually a dirty plant that was brought from outside or just by chance on you, your clothes, or the wind

    What's the Best Pest Protection Spray?

    it's definitely not useless and has way different active ingredients than that but sure that will also work just not as well imo. I have seen purecrop work on pests on mildew and the fact that you can mix it with sulfur is huge with a lot of people that like sulfur but can't mix it with oil...

    Cheap alternatives to overpriced hydroponic nutrients

    Here’s the link to the study about silicic acid and potassium silicate if anyone wants. Silicic acid seems to be way more beneficial than potassium silicate when foliar feeding https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6027496/

    What's the Best Pest Protection Spray?

    I’ve been using purecrop1 recently and I absolutely love it. You can spray it late into flower if you need to but it’s an all around insecticide fungicide and biostimulant. I mix power si with purecrop1 and I’ve had great results so far. The power si helps ward off pests and pathogens a lot as well

    Cheap alternatives to overpriced hydroponic nutrients

    Potassium silicate does not give the same benefits as silicic acid does unfortunately, especially with foliar spraying. Silicic acid increases yield, root mass and leaf mass and potassium silicate did not when foliar sprayed. There’s a great study that details the benefits of silicic acid vs...

    Cheap alternatives to overpriced hydroponic nutrients

    I tried winter frost for three runs in a row because I got a bunch of it for free and I did not see a notable difference in crystal or color or anything really. Aside from having proper nutrient ratios the only nutrient products I have seen make a significant improvement is beneficial bacteria...

    New 18 flower room nearing the finish line!

    This room is looking amazing and still 2 weeks to go. I’m very impressed with the lights and nutrient combo and can’t wait to see it perform when everything’s a bit more dialed in. This room wasn’t fully done until the 4th week of flower and it had an active(but small) spider mite infestation...

    New 18 flower room nearing the finish line!

    This was taken a week from the defoliation and things haven’t skipped a beat it seems like. Things are chunking up and getting covered in crystal! Really liking the new lights and nutrient schedule so far

    Doktor Doom? Anyone tried?

    I just fought back and have won a battle against spider mites on my flowering room of 200 plus plants. I sprayed every 2-3 days for 7-10 days. I used plant therapy first to kill anny adults and eggs it came in contact with. Then alternated with purecrop1 and repeated that for 7-10 days and then...

    *NEW INFESTATION* PLZ HELP ME DIAGNOSE

    Some good knockdown sprays I’ve used that worked really well was plant therapy and purecrop1. Plant therapy kills eggs up to adults on contact, purecrop1 kills adults and anything feeding on the plant for up to 10 days it claims, but it also doesn’t kill eggs. That plus some beneficial bugs and...

    *NEW INFESTATION* PLZ HELP ME DIAGNOSE

    Don’t use sulfur and oils close together it can burn your plant. Just finished battling them and spraying with something like plant therapy every 3 days exactly for a week or two should easily kill them. I did something similar to that and then released beneficial bugs on my plants for a...

    New 18 flower room nearing the finish line!

    Entering the beginning of week 4 here(day 22) and everything is finally running somewhat smooth. Got the automated watering system going now and finishing the defoliation. Unfortunately with a new room new problems come and those were in the form of power failures and spider mites! Luckily it...

    White/brown dots on my fan leaves, please help it’s my first time growing and I don’t want it to die on me

    On the winning side of a spider mite infestation right now. I spray every 2-3 days and rotate between plant therapy and purecrop1. Plant therapy kills both adults and eggs which is huge in breaking their life cycle. Purecrop1 kills any plant sucking insect and both of these products are...
