I'm wondering about the nature of S1 "selfed" seeds! or rather, the variation or stability they'll grow into. I'm assuming S1's don't result in identical-to-the-mother offspring, as nice as that might be, but rather something more along the lines of F2's? In particular, my friend fighting cancer who's CBD-hunting got some Thunderstruck by Sin City Seeds, which are S1's of the ACDC chemotype (24:1 CBD:THC) found in the Cannatonic strain by Resin Seeds, which seems to be the base for most high-CBD strains at the moment. Cannatonic's webpage basically states: 50% will grow into 1:1 CBD:THC 25% will grow into high CBD/low THC (but not always ACDC tho im not too sure how c…

Will humidity at 25 to 35% slow my plant grow drastically? I'm doing everything down to the t except awaiting on a humidifer and plants seem like they need one? Also I'm in my second week of vegging from nice size clones that had a good root system.

Started making myself a Dutch bucket system pretty happy so far just need a pump. Got new light coming this week these definitely aren't up to the job Sent from my SM-G900I using Tapatalk

has anyone made their own buffering solution before to help keep hydro pH level stable for longer? couldn't find any threads here about it, or not with the word buffer in the title anyway, and would love to hear other peoples thoughts about making and applying such a solution I've been reading about them for the past few hours but it was only when I came across a comment in the following thread that an easy-to-follow recipe became apparent and within reach of regular joe me (chemistry isn't in my toolbelt): https://www.researchgate.net/post/How_can_I_prepare_a_potassium_phosphate_buffer_005M_and_pH_6 It's a long thread but here is the specific comment that caught my in…

Hey guys Week 4 veg and i have noticed what looks like rust (brown) on a couple of leafs any ideas on what it could be

Hey Guys, This is my first indoor grow with random seeds. 1 looks to be some sort of indica/sativa cross while the other seems to be showing more pure sativa charactiristics. Growing in a 1.2x1.2x2m tent, 6" adjustable fan for exhaust and passive intake. 3 x 4" oscillating fans to move air round. medium is coco and 600w HPS with digital(lucius maximus) ballast. The girls are now taking water daily in their 7th week of flower and seem to look healthy apart from the lack of light to the bottom(i know most people just cut these off but i prefer to let nature do its thing i guess). I likely could've gone bigger pot sizes but not seeing any real root binding so i think i…

OK was looking for info on the different additives within 2 part nutrients and found this little treasure !! Its a bit indeapth but hell if you wanna make your own Nutrients then you need this level The Excel Spreed sheet for DIY nutrients Oh you need Microsoft Excel ..... The list of nutrient elements to use are:: Anhydrous ammonia (NH3) Ammonium nitrate, pure (NH4NO3) Ammonium sulphate ((NH4)2SO4) Calcium chloride hexahydrate (CaCl2.6H2O) Calcium nitrate (Ca(NO3)2) Calcium nitrate (fertilizer grade) (5Ca(NO3)2NH4NO3.10H2O) Calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) Calcium oxide (CaO) Calcium sulphate dihydrate (CaSO4.2H2O) Diammonium phosphate ((NH4)2HPO…

Guys &gals, Have a stupid newbie question from stupid newbie grower, If after mixing normal nutrient regime + additives,only reading 270-290 ppms When measuring runoff,does'nt go over 540 ppms. Does this mean 1; nutes are'nt strong enough. 2; level of nutes in pots,salts hav'nt built up. 3; TDS meter belongs with rice cooker graveyard or 4; WTF or FIK. Much love my peeps

I'm still trying to work out which NPK levels i want to aim for (with limited access to nutrients) Anyway here's a list i've put together so far ... i'm specifically looking at hydroponic nutrients, not soil, although some of these may be better suited for soil or whatever im not 100% sure On the left is the "reduced" NPK where I reduce the lowest value to 1 (if all values are >1) to make comparisons easier. The true/labeled NPK is in brackets on the right after the product name. In no particular order. Reduced NPK: Product (listed NPK): ---------------- ---------------------- 3 - 1 - 2 CNS17 Grow 1 - 1 - 1.5 CNS17 Bloom (2-2-3) 1 …

Hi all. So I've been scouring heaps of posts here about outdoor soil to grow in and there seems to be a number of people who recommend Searles 5 in 1 (of you can find it). Well, I think I did. (See my attached pic) I'm guessing you mix this stuff into your soil or potting mix? And as I'll be growing in pots, how do I know how much to use and do I mix it all through the potting mix or just through the top few centimeters? Sorry for asking such newbie questions but I've never done outdoor before. Cheers.

Hi everyone. My mate just got himself a plug that tells you how many watts a item or items are using and tested his equipment. His fans were on par or just over by a few watts which was good but he tested his two 400 watts hps and they were both pulling between 970 - 980 watts at the wall?? I was like that's not correct man somethings wrong there and suggested he upgraded to some new magnetic ballasts or go digital because that's way to much being pulled for a 400 watt in my opinion. Anyone have any ideas why they might be pulling this much? the lights are working fine and he has done a few runs.
