    Plenty in my base. Upwards of 5% calcium and 1.5% mag. Problems can arise with temps, humidity, super bright light , & high co2. Throwing more calcium and magnesium on top of a balanced feed in the form of a popular "calmag" supplement can exacerbate problems. What is ideal is getting stubborn...

    Foliar spray your plants a soy protein hydrolysate and a fulvic acid in veg every 5 days. And put it in the tanks in later flower. Use a full profile nutrient fertilizer (EC strength depending on cultivar and environment particulars) high in calcium and magnesium nitrate . Kiss your supposed...

    It can get heated. But damn man. What would make a cat so worked up over a gawl darn dope growing thread on a forum...or post? Just silly. Just frikin silly. Everyone wants to be so RIGHT and agreed with on the interwebby. Not just dope growing either. It's rather ridiculous.

    Ok. Got it now. I don't really even fuk with seeds much anymore so that puts me out. But still interesting. Been using 4" rockwool blocks for early veg whether seed of cuts anyways. But this is groovy. Lemme check out the thread. Thx.

    I think so. He packs em in a spare utility type room when they are like a foot or so tall in one or 2 gallon pots and hits them with a mite killer to be on the safe side. At least that's what I saw. He does final pot up in those giant 15 or 20 gallon pots and vegges the shit out of them. 4...

    That Grow Boss dude...hes about only good for extremely noob growers and jackasses that can't figure out common sense. Some of his sayings just baffle me. But for the most part he's decent for new new growers. But that's about it.

    This is so true and key. Tailor each room/plant morphology to the light particulars. I thought this from the beginning of gml' s side by side test run. And that is the method he's use to growing plant wise with hps lamps. I really think using the big panels..and to get maximum yield..he should...

    Yeah but 30%?? Huh? If a calmag supplement did that...the hydro store shelves couldn't keep it in the store long enough. Lol.

    I don't think extra calmag quite works like that. Never has for me.

    It would if he were using equal wattage. 16,000 or 8 or whatever of HLG 550's (or the new hlg600's) up against equal wattage of Gavita 1000 watt hps double ended . Then weigh in and see what the verdict is. Throw in electricity costs comparison as well..especailly air conditioning difference...

    Thing is..still the kicker is the wattage input. How much more would de hps get to justify using almost double the wattage? Hell I have no clue. But it would have to be alot. It's the wattage that's the kicker. Once you get over initial sticker shock of a bunch of quality and efficient led...

    When digis first hit the scene..honestly the failure rate was high. They sucked. Like one out of three leaving China would fail after a short time. Whatever they did..they worked out the bugs with them. The 600 watt digo ballast I sold my cousin got 10 years plus easy on them. I ran them...

    I think it was (not sure)...16,000 watts of single ended hps. And 8500 or 8600 watts of HLG 550's.

    Yep . Even if the hps side got a 20 or 30% more...still it's a no brainer when you take in the wattage. He should post up the final electric costs in light only when he does the true weigh in. That would put it all in perspective.

    Don't know about that. I would imagine dig. They are slightly more efficient (slightly) compared to coil and core. Way less heat and noise though.

    To be honest..in bigger ops..no I haven't seen much in the way of led vs hps. Especially double ended hps.

    He's using regular 1000 watt single ended hps lamps in adjust a wings (despite claims with bat wings or adjust a wings - they aren't that efficient. Those open ends make a huge difference - in a negative way). Don't know why he's not or hasn't upgraded to Double Ended hps like Gavita. Its not...
