    CF Grow COB light

    Why are you sucking the air away, instead of blowing air through the heatsink?

    1000W HPS Bulb with lowest heat output

    @CBD123THC Are you running your lights at night or during the day? Running them at night if you aren't already could help out as well. Random thought.

    1000W HPS Bulb with lowest heat output

    Just make sure your temps are fairly consistent and watch the plants for stress. Use a heater ect if you need to during lights out to only have the temperature swing a max of around 10%. And you will want a ton of air circulation with higher humidity. Adding c02 is another way to deal with...

    Starting imputs of rols

    I've seen a few tests through buildasoil that shows levels of compost should be closer to 7-10% than 30%. To reach a more balanced value of phosphorus and calcium/sodium. I wonder if you are getting that problem from having an overabundance of compost as a starting point. I'm going to look at...

    30 days I Flowering?

    I'd say anywhere from 15 to 25 days left from those last pictures. Time to water only if you haven't started all that noise yet, imo.

    Starting imputs of rols

    Kind of why I was directing this thread to be more experienced organic growers to go over what they would do if they were to start over/what they wish they knew when they started. I just thing the topic has quite a few answers and starting a conversation and civil discussions on the...

    1000W HPS Bulb with lowest heat output

    I doubt you will get more than a degree or two difference between bulbs in the best case. I'd concentrate on lowering the lung room temp or go open air. Either way good luck in the grow. But here is the vpd chart, you can totally grow with higher temps as long as your humidity is on point...

    1000W HPS Bulb with lowest heat output

    That hortilux bulb should be fine. Where is your intake and exhaust fans? And what is the ambient temp of the room the tent is in? Make sure your exhaust goes out of your lung room right after passing through the a.c. hood and that the air movement in the tent is strong enough to evenly mix the...

    1000W HPS Bulb with lowest heat output

    Different filaments and housings, they will retain and radiate heat in slightly different ways, likely this is causing heat differences as well as losses from the conversion.

    1000W HPS Bulb with lowest heat output

    If running open air is an option I'd probably just do that.

    Starting imputs of rols

    What recipe did you use? And how many cu ft did you end up with? Do you use a covercrop or any other special things?

    Looking for a simpler and cheaper nute solution

    Really depends on the pot size mate. Whatever one's you buy should have diameter measurements. Keep 2-5" between them for airflow and keep them off the direct ground. I'd probably split the area and do two flowering trays myself and alternate harvests. Trim jail is real af... Also going to...

    https://www.rollitup.org/t/2-x-600w-hps-vs-1-x-1000w-hps-what-will-yield-more.181984/ I'm just going to leave that here.

    Starting imputs of rols

    How do you determine when to water with a sip setup? I'm very unsure of the watering and the reammendment process without a soil test seems hard without experience.

    Looking for a simpler and cheaper nute solution

    2 600 hps/2 630w cmh lights will give you more height and better coverage, slightly less penetration directly under the fixture; the multiple light sources make up for it . Well worth it imo, particularly is you are doing a scrog.

    Looking for a simpler and cheaper nute solution

    For De 1000w you'd want like 3 ft clearance, so yeah you could but myself with 7 ft ceilings I wouldnt. If I were you and you are set on hps, I'd probably put 2x 600w hps in there. 2 630w cmh lights would be awesome Or like 900w high end led samsung lm561c base or later bin in 3000k. These are...

    Looking for a simpler and cheaper nute solution

    You can also mix 25-50% tap in with ro water to add more trace minerals such as calcium and magnisium if you want. GL with whatever you decide. :peace:

    Starting imputs of rols

    Anyone with rols and no till experience, IF YOU were starting today from scratch in an urban enviorment, what inputs/insects would you purchase. And how would you go about implementing the soil. Would you use SIP planters or pots for individual plants. I've never done rols, and I'm not sure I...
